Design Features
Modified PTFE Diaphragm
One-piece precision-machined diaphragm designed for flexibility and extended flexural life. The catalog states over five times the flexural life compared with conventional PTFE.
Tongue-and-Groove Seal
The seat and diaphragm design supports positive shutoff and diaphragm-to-body sealing.
Corrosion-Resistant Design
PVDF-coated stainless steel springs help reduce the effects of corrosive environments.
Multi-Turn Adjustment
The adjustable version provides multi-turn operation for precise flow adjustment and includes a removable handle.
Submergible Option
An optional configuration isolates valve components from the external environment for operation in wet or gaseous corrosive environments.
