Slab(flat)gate valve

Slab(flat)gate valve

Flat valve in detail
A product use
Flat valve applies to Class150 ~ 9 / PN1.0 ~ 16.0 MPa, working temperature - 29-121 ¡ã oil, gas, water, oil pipelines, etc. For the medium or connect piping truncated

A product features
1 and seat ring seal and using o-shape exert pre-tightening force of floating slab gate valve structure, make the import and export bidirectional seal, And the structure of open torque for common valve 1/2, can achieve easily open and close the valve
2 in the fully open channels, smooth lines, flow resistance coefficient is tiny, without pressure loss, can contain cleaning line
3, USES the filler sealing ability, without constant adjustment, structure, very deft, and sealing dependable, stuffing box also assisting sealing grease injection structure, sealed performance is absolutely reliable, truly achieve zero leakage, To solve the common valve filler most easily leak of evils
4, flat valve closed automatically unloaded inner cavity pressure to ensure safe operation
5 and enclosed structure, good performance, suitalbe for the request
