Types:
Stem Guided Valves & Cross-arms Seats
Stem guided valves &cross-arms seat features an extra wide metal to metal seal on the valve flange.The serrated upper surface on the valve gives a longer non-breathing sealbetween valve body and insert while the rigid seat cross-arms give greaterstrength and positive sealing.
The strong, thick, valve knockoff nut holds the insert tightly reducing flex and breathing which lessens thechance of foreign matter getting between valve and insert.
Three Wing Valves& FullOpen Seats
Three-wing guided valves andfull open seats is forged with premium forged steel. The flow is bigger compare with four-wingvalves and full open seats. The valve rubber can mount on the valve bodydirectly, don’t need to use plates and snap rings, have a longer service life.
Double Angle O-ring Valve
The Double Angle O-ring Valveis made with a tough one piece body to run more hours between change outs.

To prevent dry pistons and liners at start up, the valve features apatented double angle polyurethane insert that maintains cylinder primingduring pump shut down. The precise control of insert pre-load is accomplished witha flat ground insert retaining plate and split retainers. The insert can bereplaced in the field with minimum down time.
Four-wing Valves & FullOpen Seats
