Diaphragm valve 660

pneumatically-operatedfor controlshut-off

The GEMÜ 660 2/2-way diaphragm valve has a stainless steel piston actuator and is pneumatically operated. The valve was designed for dosing and filling a wide range of products. All metallic actuator components are made of stainless steel. Normally closed (NC), Normally open (NO) and Double acting (DA) control functions are available. A stroke limiter and seal adjuster and an optical position indicator are integrated as standard. Easily adjustable, integrated opening stroke and closing stroke limiter Precise stroke scale (10 scale points per turn) on the actuator top High level of reproducibility of the flow rates thanks to distance sleeves integrated in the shut-off diaphragms Fast cycle duties due to minimized filling volume Body configurations: 2/2-way body | i-body | Multi-port body | T body | Tank valve body | Welding configuration Connection types: Clamp | Flange | Spigot | Threaded connection Connection standards: ANSI | ASME | BS | DIN | EN | ISO | JIS | SMS Body materials: 1.4408, investment casting material | 1.4435 (316L), forged material | 1.4435 (BN2), forged material | 1.4435, investment casting material | 1.4539 (904L), forged material Diaphragm materials: EPDM | PTFE/EPDM Conformities*: 3A | BSE/TSE | CRN | EAC | FDA | Oxygen | Reg.
