Operation: Manual (lever, gear), Pneumatic Actuator, Motor Actuator
Normal Diameter: 1/2 Inch - 48 Inch (DN15 - DN1200)
Pressure Range: Class 150 LB - 300 LB
Working Temperature: -26°C - +120°C (180°C for PPL seat)
End Connection: Wafer, Lug, Flanged
1st Offset: The shaft centerline is positioned behind the disc centerline, reducing contact between the disc and seat before full closure. This allows for continuous engagement of the seating surface.
2nd Offset: The shaft centerline is offset from the valve and pipe centerline, creating a linear sealing surface. When the valve opens, the disc seal quickly disengages from the seat, significantly reducing friction and wear on the sealing surfaces.
