Professional Manufacturer of Hygienic Divert Seat Valve/Reversing Valve/Single Seat Valve

Sanitary Divert Seat Valve is one of the constructive types of control pipeline valves. This is the most commonly used type of control valve for both continuous (analog) and discrete control of flow and pressure.

Divert Seat Valve perform this task by changing the flow rate of the medium through their flow area. The material of manufacture of reversing valve depends directly on the type of working medium with which the valve will come into contact. In reversing valves, a plunger serves as a movable element, which can be needle, rod or poppet. The plunger moves perpendicular to the flow axis of the medium through the seat (or saddles), changing the flow area.

The most common ones are double-seat valves, since their shutter is well balanced, which allows them to be used for continuous pressure regulation up to 6.3 MPa in pipelines with a diameter of up to 300 mm, while using actuators of lower power than single-seat ones. Single-seated valves are most commonly used for small bore diameters due to their unbalanced plug.

Also, the advantage of two-seat valves is that with such a design it is much easier to ensure the tightness required for shut-off and control valves using a plunger that has a special regulating profile for contact with one seat, and for fitting into another seat – a sealing surface for tighter contact.
