Valve Internal Construction

Working Principle

The open and close assembly of parallel gate valve is composed of wedge, disc follower and

floating gate among others. The unique part is the parallel double floating gate seal assembly

to replace wedge type gate, the working principle is as followed:

When the parallel gate valve is closed, the output force of the actuator is transported to the disc

follower from the wedge to provide two equal forces to obtain excellent seal performance.

The bevel angle of the wedge is larger than the self-locking

angle of the slope, at the opening it first overcomes the friction force between the wedge and

the disc follower, the stem lifts the wedge, because of its own weight, the disc follower produces

axial setback, therefore no friction in the sealing pair, moreover the gap between all kinds of

components is big, the open action is rapid and no jamming.

In the process of opening and closing, there is sliding friction movement between the wedge

and disc follower, however there is no sliding friction movement between the floating gate and

the seat ring, only loose and tension action, therefore it greatly reduces the friction between the

gate and the seat sealing surface to prolong life span.

The components of the shut-off device are movably connected, because of the fluid pressure,

the gate can self-rotate during the opening and closing process to self-clean the sealing

surface to furthermore prolong sealing and life span. And it can automatically compensate the

deformation and manufacturing error caused by temperature change to prolong sealing life.

In order to eliminate the increasing chamber pressure caused by temperature change, a small

hole is opened on the inlet gate, during the closing process; automatic turn-on between the

chamber and the inlet hole can vent and balance the pressure in the chamber. Moreover

because of the differential pressure on the outlet gate, it can further fits the seat ring and has

reliable sealing performance.
