DESIGN TO BS 5351
Cast with uniform wall thickness, smooth flowing contours and generous fillet radii to prevent stress concentrations. Designed for structural stability, mechanical strength and safe weld ability. Precision machined.
TWO/THREE PIECE DESIGN CONSTRUCTION
All ball valves are designed with either two-piece construction or three-piece construction.
MIRROR FINISH BALL
Precision machined and buffed to produce mirror like finish, minimum wear on the seat. All balls are designed to withstand the full hydrostatic body pressure.
REGULAR/REINFORCED, PTFE SEATS AND SEALS
Soft seat rings processed from PTFE oil free granular resins of virgin material completely free of reclaimed processed material is used. Reinforced PTFE seats can be provided on request.
Blow out proof stem is sized so that its connection to the ball is capable of withstanding, satisfactorily the maximum operating torque.
All valves are lever operated with quick quarter turn on-off operation.
STRONGER, LEAK PROOF BODY, END CONNECTION JOINT
The design of the body-end connection gasket joint is critical. Its compression is better controlled in a fully enclosed cavity.
Flange on class 150 and 300 valves have 1/16” raised face.
