Features and benefits:

Uni-directional wafer valve designed for general industrial service applications.The design of the body and seat assures non-clogging shutoff on suspended solids.


Guides design allow for a tighter shut-off ,eliminates any potential clogging when valve shutoff.

The internal body design ensures flow smooth,avoids any accumulation of solids that would prevent the valve from closing.

Full port design, greater flow and minimum pressure drop.


The bottom of the gate edge is machined to a bevel,that provides stronger cutting and tighter seal.

The gate’s thickness or material can be changed on the reuqest for high pressure requirements.


The seat retainer ring locks the seal in the internal of the valve body,that prevents seat from direct flow flushing.

Replaceable side entry seat reduces maintenance cost.

Soft seat/Metal-metal seat.
