STRUCTURAL FEATURES

Fully-lined, quarter turn non-lubricated plug valve ideally suited for corrosive application. Locking of liner to body and molding technique permit use on many chemical services with higher pressures and vacuums without fear of liner collapse, shrinkage,stress cracking and blowout. Excellent sealing capability.

All sealing surfaces are machined to close tolerances, providing tight shutoff.

(1) Independent wrench stops are cast in the cover.
(2) Three stainless steel adjusting screws, silver-plated for added corrosion resistance, give parallelism to the plug through the thrust collar, assuring uniform position of the plug in the body.
(3) The multiple top seal is designed to transmit sealing forces diagonally across the delta ring and vertically on the diaphragm to seal the plug shank, providing an added safeguard against
hazardous fluids escaping to atmosphere
(4) PFA are melt processible and offer maximum density and elimination of stress cracking at the corners, affording longer maintenance-free service for the liner and the valve.
(5) The liner is locked to the casting by means of cast dovetail recesses and machined grooves,permitting the valve to be used on high vacuum and pressure applications without liner collapse,shringage or blowout.
(6) The bottom seal adjustment provides a positive means of maintaining tight shutoff.
(7) The body of the valve is coated with corrosion- resistant paint to retard external corrosion and rust.
