Side Entry Forged Steel Trunnion Mounted Ball Valve
Side Entry Forged Steel Trunnion Mounted Ball Valve
The
SV side entry forged steel trunnion mounted ball valve has a
trunnion mounted ball supported by two floating seats.
The pressure of media will push the two floating
seats seal ring at both ends to attach the ball’s surface tightly to ensure
bidirectional reliable sealing.
The
SV high pressure forged trunnion mounted ball valve has forged steel body
which is suitable for higher pressure than casting body and can avoid
shrinkage cavities, pin holes, cracks, sand holes and other defects may occurring
in casting body.
