High Pressure Gate Valve

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.

High pressure 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. Designed for use in extreme service our xtrm valves meet the most challenging environments in the modern oilfield.

Cast iron gate valves flange. The gate faces can be parallel but are most commonly wedge shaped in order to be able to apply pressure on the sealing surface. Gate valve is designed to open and stop the flow. Gate valves are more commonly used in refineries and petrochemical plants where pressure remains relatively low but temperature may be very high.

These gate valves are ideal for refinery chemical and other process applications. Designed to withstand high pressures and temperatures these valves feature 410 stainless steel rising stems and wedges and carbon steel handwheels. This type works best in high pressure and high temperature applications. The gate valve should not be used as a flow regulating device.

Gate valves are used less in upstream oil and gas production facilities due to high operating pressures long opening closing times and severe environmental conditions when operating in marine. Body cavity pressure increases or decreases the seal between the body and bonnet in this type of gate valve. 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. The gate valve can be mounted to a pipeline in any position.
