Factory Direct Sale Manual Resilient Seat Wedge High Pressure Forged Steel Gate Valve

Product Description

This heavy duty class 800 forged carbon steel Gate Valve is suitable for the most demanding of process applications. When open the media will flow with a minimal amount of turbulence and pressure drop through the valve and industries where the isolation of viscous fluids and liquid are required.

The valve is designed to API602 and has an outside screw and yolk with rising stem. The handwheel operates the gate valve for both isolation applications only.

Why use gate valves: these valves provide a positive tight shut off in the horizontal or vertical position for process fluids in pipelines. They also offer a small amount of control and are used to throttle steam, gas or liquids. Easy to operate and the preferred choice over ball valves by engineers to isolate trapping stations.

High Pressure Forged Steel Gate Valve can be operated by pneumatic actuator,electric actuator,intelligent control head and manual operation.There are a variety of standards provided to customers,such as,DIN,API,ANSI,and so on

A high-pressure gate valve operates manually or through automation. The basic working principle remains the same whether the valve is manual or automated: the actuator rotates the stem to start/stop flow. The valve starts when the actuator rotates clockwise for several turns. As such, the stem converts the rotary motion to linear movement.

This linear motion causes the valve disc to move upwards, leaving the valve open. With the valve open, fluid starts flowing through the valve. The valve stops flow when the actuator is rotated counterclockwise, forcing the stem and disc to move downwards. As such, the disc seals the valve's central hole where liquid flows through. At this state, the valve is closed, and there is zero fluid flow.
