Master Lock Rotating Gate Valve Lockout, for 2" - 5" Valve Handle Diameters List Price: $19.88 Sale Price: $14.63 |
|
The Master Lock rotating gate valve lockout is a lockable thermoplastic shell that surrounds and covers a gate valve handle and aligns two flanges to form a hasp with up to four holes for padlocks (sold separately) to help protect against accidental valve opening as part of a lockout-tagout (LO/TO) safety procedure required at facilities where the flow of a fluid is controlled by a gate valve. This lockout consists of two halves; one slightly smaller half fits inside the larger half when not in use, for installation in confined spaces and a compact storage footprint. To deploy, the lockout is placed over a gate valve handle, with a center hole fitting over the gate valve stem, then the inner half is rotated out to surround the rest of the gate valve handle. Where the two halves meet, flanges from each half align to form a hasp with up to four locking holes. A padlock shackle placed through any of these holes obstructs the inward rotation action of the lockout, thereby prohibiting access to the gate valve handle. Multiple locking holes provide the ability to require multiple authorizations to allow operation of a locked out gate valve during maintenance or repair. This lockout is made from red Zenex thermoplastic, which is nonconductive and functions in extreme temperatures: -50 to 350 degrees F (-46 to 177 degrees C). On the outer (or top, depending on the orientation of the gate valve,) part of the shell a small circular area can be removed to allow installation over rising stem gate valves. This product includes three (English, French, and Spanish) high-visibility warning labels with erasable areas for task-specific details. One label fits on the lockout at a time. When used according to manufacturer's recommendations, this product is covered by a limited lifetime warranty against defects in workmanship or materials. Lockout-tagout (LO/TO) safety procedures, as defined by Occupational Safety and Health Administration (OSHA), require that lockout devices be durable and standardized. Lockout devices use color, warning labels or tags, and a physical barrier to temporarily prohibit machine operation or power activation, and help reduce accidents, during maintenance or repair. Gate valve lockouts are lockout devices that temporarily prohibit operation of gate valves by covering the handle with a lockable shell. They are often used to secure fluids in the off position during maintenance or repair when multiple workers are on the job. Master Lock manufactures padlocks, combination locks, and related security products. The company, founded in 1921, is headquartered in Milwaukee, WI. |

Milwaukee Valve P901 Series Bronze Gate Valve, Class 150, Quick Opening Stem, Lever Handle, 4" NPT Female List Price: $7,811.92 Sale Price: $2,979.36 |
|
This class 150 Milwaukee P901 series bronze gate valve has a quick-opening stem with a lever handle and female National Pipe Taper (NPT) threads on both ends. The bronze construction of the gate valve and its brass double discs provide higher strength and resistance to corrosion than steel. The valve has a brass quick-opening stem that is manually operated by turning a malleable iron lever handle, which pushes the discs into the valve’s passage to stop flow between pipes. The pressure between the two discs forms a tight seal to stop potentially dangerous fluids from leaking and mixing. With the exception of the 4" valve that has an O-ring, this valve has graphite internal stem packing. The valve has female NPT threads on both ends for connecting to male threaded pipes. The maximum pressure of this class 150 valve is 300 pounds per square inch (gauge) (psig) for water, oil, and gas pressure (WOG) and 150 psig for saturated steam pressure. Class is a standard relating to tolerance, construction, dimension, and wall thickness, but it is not a direct measurement of maximum working pressure. The valve is appropriate for quick draining and steam blow-off use and other heating and plumbing applications. Gate valves control flow in a piping system by lifting a gate out of the path of steam, fluids, or gases. They are designed to block or permit flow, as the vibrations and force of flow repeatedly striking a partly lowered gate can damage the gate and seats. To accommodate different flows and pressure requirements, gates come in four types: solid wedge (appropriate for almost all liquid service), flexible wedge (appropriate for steam service), split wedge (appropriate for normal temperature, non-condensing gas and liquid service, including corrosive service), and parallel disc (appropriate for high and low pressure applications). Hand wheels or levers activate the screw mechanism in the valve’s bonnet, which comes in various designs, to open and close the gate. Union bonnets are preferable for building service piping, threaded-in (or screw-in) bonnets work well for lighter-duty usage, and bolted body-bonnet connections are used primarily in iron multi-turn valves. Most gate valves have either a rising stem, which moves up and down with the gate, or a non-rising stem, which remains fixed in place. When closed, the gate and its seats form tight planar sealing surfaces, ideal for linear liquid flow. Gate valves are used in air, gas, liquid, and steam applications. The Milwaukee Valve Company manufactures manual and actuated valves, controls, and control accessories. The company, founded in 1901, and headquartered in New Berlin, WI, meets International Organization for Standardization (ISO) 9001:2008 and 14001:2004 standards. |

Introduction of Ball Valve
Ball valve was invented in 1950s. It is also one of the fast-developed valves in recent years, especially in USA, German, Japan, France, Italy, Spain and UK where ball valves are widely used. The types and quantities of ball valve is still increasing at speed, and its engineering development starts to move towards applications of high temperature, high pressure, large port, secure sealing, longer duration, great adjustment and multiple functions. Due to dedication to research and development, the stability and capability of ball valve managed to reach the higher level of achievement, which is able to take place of gate valves, check valves and throttle valves in applications. Ball valves are widely used in aerospace, petrochemical, pipelines, food and beverage and construction.
The Main Features of Ball Valves:
1. Low Flow Resistance
The passage of ball valve can be divided into full port and reduced port. Whether full port or reduced port, its factor of flow resistance are smaller, especially the full-port type. The passage diameter of the full-port ball valve is the same as the pipe diameter that makes the partial resistance equal to friction resistance of the pipe. Therefore, full-port ball valve has the lowest flow resistance compared to other types.
2. Quick and Easy to Open and Close
Its 90-degree manual handle is easy and quick to open and close. In some cases, it only takes as little as 0.05~0.1 second to finish the action. So it is preferable in automation system.
3. Great Sealing
At present, most of the sealing element is made of flexible materials such as Polytetrafluoroethene, PTFE. Sealing element combined with metal and non-metal materials is called soft sealing. Generally speaking, effectiveness of soft sealing is easy to guarantee, and it requires low machining precision and rough surface.
4. Longer Duration
The self-lubrication feature of PTFE reduces the friction between sealing element and ball. Besides, the improvement on machining skills lowers the rough surface of the ball, increasing the life span.
5. The smooth surface of passage facilitates the transportation of sticky fluid, serous fluid and particles.
6. It can work smoothly without applying lubricants which is ideal to handle corrosive medium and low-boiling-point fluid.
7. Under condition of higher pressure and temperature, it can do bi-directional sealing.
8. The sealing elements inside the body and seat can fully separate the medium that can prevent erosion.
9. Its compact construction and light weight is ideal to handle low temperature medium.
10. Its symmetrical design, especially welded ball valve, is easy to take the pressure from pipeline.
11. The welded ball valve can be directly buried underground to prevent the components inside the body from erosion. The duration can last up to 30 years. It is mostly used in oil and gas sectors.

In a petrochemical company how can we find out where we should use globe valve and where we must use gate valv
i mean what are the principle and rules which we should obey in order to use globe or gate valves in piping system . are there any procedures, standards or rules which can tell us how to use the valve and where to use them?
what rules applies in selecting the proper valve ? are there any procedures or standards based on which the appropriate valve , gate or globe can be chosen for pipying system ?
