The WCB GOST 5762 metal-to-metal seated wedge OS&Y gate valve is a type of metal hard sealing wedge gate valve designed for industrial applications that require reliable and efficient shut-off capabilities. Here is an introduction to this specific WCB GOST 5762 metal seated wedge OS&Y gate valve:

Specification introduction of WCB GOST 5762 metal-to-metal seated wedge OS&Y gate valve:

Design and Construction: The WCB GOST 5762 metal to metal seated wedge OS&Y gate valve conforms to the GOST 5762 standard (Russian standard), which specifies the technical requirements for WCB gate valves used in various industries. It features a wedge-shaped gate that moves vertically to control the flow of fluid through the valve. The valve body of the GOST metal to metal seated wedge gate valve OS&Y is constructed from WCB (cast carbon steel), known for its strength and durability, making it suitable for demanding operating conditions.

Metal-to-Metal Seating: The gate and seat surfaces of this GOST metal seated wedge gate valve are designed with a metal-to-metal sealing arrangement. This means that when the gate is fully closed, the metal surfaces of the gate and seat come into direct contact, providing a tight and reliable seal. This metal-to-metal seating design of those GOST metal to metal seated OS&Y wedge gate valves offers excellent resistance to wear, corrosion, and high temperatures, ensuring long-term sealing integrity.

OS&Y Design: That GOST 5762 metal to metal seated wedge gate valve follows the OS&Y (Outside Screw and Yoke) design, which means that the valve stem is located outside the valve body, allowing easy visual indication of the valve’s position. The rising stem moves up and down as the gate inside the valve body opens or closes, providing a clear visual indication of whether the valve is open or closed.

Size and Pressure Ratings: This WCB GOST metal to metal seated OS&Y wedge gate valve is available in a range of sizes, typically from DN50 (2″) to DN300 (12″), to accommodate different piping systems. It is designed to withstand high-pressure applications, with pressure ratings commonly ranging from PN10 to PN16 (Class 150).

How WCB GOST 5762 metal-to-metal seated wedge OS&Y gate valve works:

The WCB GOST 5762 metal-to-metal seated wedge OS&Y gate valve operates using a simple but effective mechanism. Here’s a breakdown of how it works:

1. Open Position: When that GOST OS&Y gate valve is fully open, the gate is raised to its highest position, allowing unobstructed flow of the fluid to flow through the valve. The rising stem is also in its highest position, indicating that that GOST OS&Y wedge gate valve is open.

2. Closing the Valve: To close that OS&Y wedge gate valve, the stem is turned in a clockwise direction (when viewed from the top) using a hand wheel or an actuator. As the stem rotates, it causes the gate to move downwards towards the valve seat.

3. Wedge Gate Sealing: As the gate descends, the wedge shape of the gate causes it to come into contact with the matching wedge-shaped seat inside the valve body. This metal-to-metal seating design ensures a tight and reliable seal to prevent any flow of fluid when that GOST gate valve is closed. The contact between the gate and seat surfaces creates a bidirectional sealing, effectively halting the fluid flow in either direction.

4. Fully Closed Position: When the gate reaches its lowest point, it forms a complete seal against the valve seat, effectively closing off the flow of fluid. At this point, that WCB GOST OS&Y wedge gate valve is fully closed, and the rising stem of the GOST OS&Y gate valve is in its lowest position, providing a visual indication that the valve is shut.

5. Opening the Valve: To open that WCB GOST metal to metal seated OS&Y wedge gate valve, the valve stem is turned counterclockwise, causing it to rise. As the valve stem moves upward, the gate is lifted away from the seat, creating an unobstructed passage for fluid flow. Once again, the valve stem position indicates whether the GOST OS&Y gate valve is open or closed.

It’s important to note that proper operation and maintenance of the WCB GOST 5762 metal to metal seated OS&Y wedge gate valve, including regular inspection and lubrication of the outside valve stem, are essential to ensure smooth functioning and extend the valve’s lifespan. Applying excessive force or neglecting maintenance can lead to operational issues or premature failure.
