Apollo 77-900 Series Bronze Ball Valve with Actuator Mounting Pad, Two Piece, Inline, Lever, 3/4" Straight Thread Female List Price: $42.06 Sale Price: $30.98  |
|
The Apollo 77-900 series bronze two-piece inline ball valve has a lever handle, an actuator mounting pad, and female straight threads on both ends. It is made of bronze for higher strength and corrosion resistance than brass, and has a zinc-plated steel lever handle with a vinyl sleeve for manual on/off control. This valve has a mounting pad for attaching a quarter-turn electric or pneumatic actuator to provide automated operation, and an SAE J512/J514 o-ring boss connection for creating a fluid-tight seal. Reinforced polytetrafluoroethylene (RPTFE) seats and multifill polytetrafluoroethylene (MPTFE) stem packing reduce the possibility of leakage. The valve is full port for reduced friction; its inner diameter is the same as the inner diameter of the pipe it connects to for maximum operating efficiency. The maximum pressure is 600 pounds per square inch (gauge) (psig) for use with water, oil, and gas (WOG) and 150 psig for saturated steam, and the temperature range is -20 to 450 degrees Fahrenheit. This ball valve is for use in water lines, processing plants, and agricultural applications and meets standard MSS SP-110 for quality assurance. Ball valves use a spherical disc to control the flow between pipes, tubes, or hoses. Flow is allowed when the hole that pierces the ball-shaped disc is in line with the inlet and outlet of the valve. Flow is blocked when the ball is horizontally swiveled 90 degrees, so that the hole of the ball is perpendicular to the opening of the valve. Ball valves can be referred to as full port or reduced port (also known as regular or standard port) depending on the inner diameter of the valve. A ball valve is full port if the hole of the ball is the same size as the inner diameter of the connecting pipeline (resulting in lower friction) and is reduced port if the hole of the valve is one pipe size smaller than the pipe, resulting in less flow through the valve than through the shaft of the pipe. Ball valves may have a handle or lever that aligns with the ball’s position (open or closed) for manual operation. They are primarily used in air, gas, liquid, and steam applications. Apollo manufactures ball, mixing, and relief valves, actuators, water gauges, marine fittings, heating and plumbing products, and backflow prevention devices.

Here are some more information for Valve Actuator:
A turbocharger uses either an internal or external wastegate to control the exhaust gas so the turbocharger can maintain a set amount of boost pressure.
Integral Wastegate
With an internal or integral wastegate, the turbine housing of a turbocharger has a built-in flapper that opens and closes through the use of an actuator. The internal is more commonly found on vehicles that came turbocharged from the factory. When the set boost level is reached the flapper vents or redirects the exhaust gasses so they exit through the downpipe and thus attempting to maintain a steady boost level.
The actuator is normally being controlled by an electrical boost solenoid which has vacuum lines that control it. GM part number #1997152 is a popular choice that has been adapted to work on many vehicles either foreign or domestic. Some OEM boost solenoids for Volvo, Audi, and others accomplish the same thing.
One vacuum line typically runs from the intake side of the engine or turbo compressor housing to provide the actual boost pressure which the engine is operating. This line from the intake to the first port on the solenoid is sending positive pressure which is then bled off at the solenoid to deliver this output pressure to the actuator. The actuator is basically a spring inside a canister with a diaphram that is controlled by the pressure sent to it from the solenoid.
With the solenoid disconnected the boost level is determined by the spring in the actuator canister. This is also known as base boost, or the lowest boost setting that the turbo can be ran. A modification to the actuator by placing a stiffer spring will raise the base boost and is usually necessary if the vehicle has been modified to run a much higher than stock boost level.
External Wastegate
The external wastegate application is usually an aftermarket product which is not built into the turbocharger. The placement of the external can vary depending on the application and fitment issues. A complete twin turbo kit for a 2005-2008 Corvette C6 has the turbos/wastegates rear mounted because of lack of space under the hood.
External wastegates can be either vented to the atmosphere or redirected so they are sent out the exhaust system. When they are vented to the atmosphere the noise produced is considerably loud and may push the legal limits for noise so be sure that you are aware of potential risks.
When the external wastegate is tied into the exhaust the amount of noise is minimized and similar to the noise level from an internal wastegate. Some people have mistaken a wastegate for a blow off valve and these are two completely different components that serve different purposes. The blow off valve emits a sound that is more of a sharp swoosh, slightly high pitched. The external wastegate vented to the atmosphere is much deeper and not nearly as smooth. A small turn down pipe is typically attached to the wastegate to direct the discharge away from any place that may not take well to heat.
Manual Boost Controllers
When you want to raise the boost, there are many gadgets out there on the market that claim to offer solid boost control. Before you go and spend $500 or so on a fancy electronic boost controller, lets first take a look at what is happening.
As previously mentioned with the integral wastegate, the actuator is used to hold the flapper shut by the use of spring pressure. The preload must be set accurately or there will be a serious lag in building boost or if its set too tight can cause a boost spike and damage an engine. Its extremely important to set the preload properly, whether you are running stock or higher boost levels.
A simple but extremely effective $45 boost controller can provide excellent boost control. The boostvalve is a product that has been proven reliable for years and they offer additional springs to allow higher boost settings.
Maintenance
Integral wastegates can become sticky, where the wastegate flapper becomes stuck or just doesn't swing freely. This is an important inspection that could be costing you a lot of performance. If the flapper doesn't open and close smoothly then it may get hung up causing a lag in building boost or boost spikes to overcome the spot where it hangs. A product from GM called heat riser lube can be injected to help loosen up the flapper.
The vacuum lines that run to the boost solenoid may need to be inspected depending on the condition or age of the vehicle. Replacement silicone vacuum lines are usually a good choice.
The last suggestion is to take a close look at your datalog files to see just how stable your boost control is, whether it spikes or drops off. A properly setup wastegate can make all the difference in terms of overall performance from a turbo engine, and you may just need to make a few small adjustments to see dramatic improvements in performance.

The Leading Distributor Of Solenoid Valves
Asco valves, whether designed to better channel the flow of steam, air, water or some other compressed fluid medium, are the choice amongst professional engineers for motion control tasks of just about any nature. The fact is that contromatic valves from Asco Valves range from the simplest on-off solenoid valves to complicated computer operated valve assemblies meant to serve as complete flow control solutions.
Pistons by their nature produce a simple linear motion. However, when a piston is conjoined to a crankshaft via a hinged arm, that linear motion can be mechanically transmuted into circular motion. Piston actuated valves get switched into their secondary or alternate position by the motion of a crankshaft, move fluid or gas from one space into another, a common technique used in internal combustion engines and a great many other machines - a great many of which contain piston actuated valves distributed by Asco, due to the valves' famed high quality and ability to withstand wear and tear.
The term 'contromatic valves' is one without a proper formal definition, and arose from the efforts of corporate marketers to find a neat umbrella term that could be used to describe the gamut of Asco valves, including solenoid valves and piston-actuated valves. 'Contromatic' was coined as all of these devices allow for greater measures of control, be it manually, at the hands of an operating technician at a switchboard, or in the fashion of a servo valve.
Servo valves are capable of responding to changes in the operation of the machine to which they're adjoined. This is essentially achieved by means of the principle of negative feedback, whereby the actual, present functioning or position of a device is compared to the desired or intended 'control' position.
A simple example of this is the original thermostat, known at the time of its inception as the 'furnace regulator', which was developed and patented by Albert Butz in 1885. The device was constructed in such a way that when the ambient temperature of the room fell below a given temperature, the device would close a circuit and energize a solenoid, which in turn would deploy its armature to move a motor gear, turning a crank that would allow more air into the furnace, thus increasing ambient heat up until a certain point, at which time the engine would turn another half revolution, raveling the chain back up and closing the furnace's damper flap.
The incorporation of a solenoid into the device was, at the time, a rather rare thing. Indeed, it was only in 1910 that Asco Valves incorporated solenoids into its valves, becoming the distributor of the first commercially available solenoid valves. The company's later expansion into piston actuated valves would secure its standing, at that crucial time, at the head of a relatively small field of manufacturers, a fact that's turned it into an international engineering and parts supply powerhouse.
Still, Asco Valves is not alone amongst distributors that havestood the test of time. Many of the dominant companies in the production of valves and motion-actuation systems are over half a century old. Among them is Honeywell, a corporation that, aside from solenoid valves, manufactures pneumatic and hydraulic systems, and can trace its roots back as far as 1886 (and the aforementioned Albert Butz).

Could someone describe the electical input signal for swiming pool valves actuators ?
Hi, I d like to know the electronic input signal characteristics to drive a simple 24V or 12 V AC rotary valves actuator.
I haven't been able to find detailed specs of the input signals for actuators. Usually the control input signals consist of a 3 wire set.
I guess one is power, and the other 2 are controls..but how does it work ? What would be the other signal to run the valves clockwise and then anti-clockwise ?
Thanks for your help or any comments.
Assuming that there is no control signals to drive the valve actuators since you have mentioned 24/12v rotary valves. Here I believe is that one wire is the ground and other two positive and negative which will be interchanged in such a way that in one position valve opens and in the other position the polarities are reversed and valve closes. I could be wrong also.
2000 Mazda Millenia S review from North America
What things have gone wrong with the car? I was looking for a long-distance highway cruiser, and discovered that instead of an ancient Lexus ES300, I could get a two-year old Mazda Millenia S for around the same money.
Thanks for visiting!
