• Forged Steel Gate Valve Class 800

- Forged Steel Gate Valve Class 800

- bolted bonnet, outside screw and yoke type.

- Forged Steel Gate Valve Class 800 rising spindle construction body and bonnet made from high quality forgings.

- Forged Steel Gate Valve Class 800 are Bolted Bonnet, outside screw and yoke type, Rising Spindle construction. Body and bonnet made from high quality forgings.

- Relia Forged Steel Gate Valves in size 1/2 (DN15) to 2 (DN50) to suit various critical, non-critical applications and pressure rating up to Class 2500.

- This heavy duty class 800 forged  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 forged steel gate 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 forged steel gate valve: 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.
