The sliding gate control valve is a type of high performance, variable orifice, control valve with a seat design that provides a non-turbulent, straight through flow path.
The unique port characterization breaks the fluid flow into multiple streams creating a reduced field of energy and less turbulence. This results in greater service life, quieter operation and a control valve that performs at the highest levels possible within extreme conditions.
These types of valves can operate at temperatures around 975 degrees F and pressures of 1,450 psig. They are available in 1/2″ through 10″. These style valves are normally available in Carbon Steel and 316 Stainless Steel, and Hastelloy.
This type of control valve is used in a wide range of process engineering control applications and is excellent at controlling steam, fluids, and gases.
A variety of pneumatic and electric actuators can be mounted to the sliding gate control valve depending on location and available energy supply.

Advantages of sliding gate control valves:
- Sliding gate valves combined with with digital positioners provide excellent controllability and accuracy.
- Short opening & closing times, and maximum control performance, due to short stroke of sliding gate valve.
- High control with low leakage rates & long service life.
