Flat Gate Valve:
1.Small flow resistance
2.Low torque operation
3.Short face-to-face dimension
4.Simple structure
CHARACTER
1. seat is o-type ring and floating seat structure, make flat valve import and export seal;
And the structure of the opening and closing moment for the common valve only 1/2, can achieve easily open and close the valve.
2. When full open, channel smooth to linear, flow resistance coefficient is tiny, the pressure loss, can connect MAO qiu cleaning line.
3. The three, with the packing structure of sealing ability, without constant adjustment, features very light open and close and sealing is reliable, stuffing box place an assisting sealing grease injection structure, sealed performance is absolutely reliable and get a true zero leakage;Solve the common valve packing place the most easily leak of evils.
4. flat valve closed can automatically unloaded lumen high pressure, ensure safe operation.
5. fully closed structure, protective performance is good, suitalbe for the requirements.

1 . Valve seat adopts the structure of O-ring seals and pretightening float valve seat, the soft
sealing inlays fluoroplastic, it provides the function of double sealing: fluoroplastic to metal and
metal to metal. And at the same time, the fluoroplastic can remove the dirt of the gate disk.
2 . Of the metal to metal sealing, there is a grease injection structure outside the valve, grease
injects the sealing part through the seat, in this way achieves the aim of zero leakage.
3 . Through conduit gate valve always coincide with the sealing surface,whether the disc is full
open-or fullclosd; sealing surface to be protected from scouring by media dilectly, thereby extending
the service life. In fulltime, smooth channel for the direct and flow resistance coefficient is extremely
small, no pressure loss, leading to Pig.
