Tank Bottom Sanitary Diaphragm Valve With Butt Weld Connection Membranes Seals

Tank Bottom Sanitary Diaphragm Valve With Butt Weld Connection , Membranes Seals

Our tank bottom diaphragm valves for high purity applications in the pharmaceutical, food, fine chemical and cosmetic industries.

ASME BPE compliant.
Valves are rated for full vacuum.
Valve opens and closes with easy quarter-turn operation.
Internal seat design produces a bubble-tight seal.
Spring-loaded washers create a live-loaded stem assembly for positive sealing.
Encapsulated body gaskets minimize cold flow and reduce recesses where media could accumulate and contaminate the process. Standard bottom-entry stem provides protection from inadvertent stem removal. Engagement between the slot and ball is specially designed for high torque applications. Stainless steel handles with vinyl end cover are designed for ;a sure grip. The handle position visually indicates whether the valve is open or closed
Unique pad radius facilitates efficient drainage and reduces the pocket area above the ball.
