A corrosion-resistant pneumatic diaphragm valve is suited for highly corrosive dosing applications and open/close applications. Type 604/605 is designed and tested to surpass two million lifecycles, according to the manufacturer. The 0.5" (d20) size valve is available in body materials such as PVC, CPVC, PROGEF standard PP and SYGEF standard PVDF. The pneumatically actuated dosing valve is pressure rated at 90 psi unidirectional with operating temperatures ranging from -4 to 284°F (-20 to 140°C), depending on body material. The threaded bonnet design eliminates the need for metallic body bolts and re-torqueing after hot line shutdowns.
