High Pressure Gate Valve

Cast iron gate valves flange.

High pressure gate valve.

These gate valves are ideal for refinery chemical and other process applications. The gate faces can be parallel but are most commonly wedge shaped in order to be able to apply pressure on the sealing surface. A complete range of gate globe and check valves for all of your high pressure and high temperature applications proven over years of service in thermal and nuclear power plants as well as oil and gas industry applications around the world. Stafsjö s knife gate valves slh and slx are designed for the most demanding high pressure applications with slurry and other abrasive media where operation reliability and low life cycle cost are emphasized.

Gate valve is designed to open and stop the flow. Designed to withstand high pressures and temperatures these valves feature 410 stainless steel rising stems and wedges and carbon steel handwheels. Body cavity pressure increases or decreases the seal between the body and bonnet in this type of gate valve. A gate valve also known as a sluice valve is a valve that opens by lifting a barrier gate out of the path of the fluid gate valves require very little space along the pipe axis and hardly restrict the flow of fluid when the gate is fully opened.

These rugged gate valves can be used fully open. High pressure xtrm gate valves the mhwirth xtrm gate valve products offer an advanced and robust pressure control solution to the industry. The gate valve should not be used as a flow regulating device. The slh is designed for pressure up 20 bar 290 psi while the slx is designed for 50 bar 720 psi.

It should operate in a close or open position. This type works best in high pressure and high temperature applications. Os y or rising stem gate valves outside stem and yoke os y valves are characterized by the rising threaded valve stem as the valve opens. Gate valves are more commonly used in refineries and petrochemical plants where pressure remains relatively low but temperature may be very high.
