Pneumatically operated diaphragm valve GEMÜ 687

The GEMÜ 650TL diaphragm valve is a manual tapping valve with automatic closing function which is pneumatically operated. The "keep-closed" override of manual operation is via a stainless steel handwheel. The valve can only be operated (opened / closed), if a control medium is applied to the actuator. When the control medium supply is switched off, the valve closes and can no longer be operated manually. — Hermetic separation between medium and operator — Ergonomic handwheel — Additional pneumatic actuator for closing from a central control system — CIP/SIP capable — Optional flow direction and installation position

The GEMÜ 653 and GEMÜ 654 2/2-way diaphragm valves have a stainless steel operator housing and are manually operated. The valve is available in two versions. GEMÜ 653 has a handwheel in high temperature and chemically resistant plastic. GEMÜ 654 has a stainless steel handwheel. Both types are also available with concealed bolt mounting (design D). An integral optical position indicator is standard. —Handwheel design allows minimal heat sink —CIP/SIP cleaning and sterilising capabilities, autoclave capability —The service life of the diaphragm is increased to a maximum (by the optional seal adjuster) —Stroke limiter available (optional)

The GEMÜ 650 2/2-way diaphragm valve has a stainless steel piston actuator and is pneumatically operated. The valve is designed for use in a sterile environment. All metallic actuator components are made of stainless steel. The compression springs of diaphragm sizes 80 and 100 are made of epoxy coated spring steel. Normally closed (NC), Normally open (NO) and Double acting (DA) control functions are available. An integral optical position indicator is standard. —Hermetic separation between medium and operator —Suitable for inert and corrosive liquid and gaseous media —CIP/SIP cleaning and sterilising capabilities —Autoclave capability —Optional flow direction and installation position

The GEMÜ 601, GEMÜ 612 and GEMÜ 673 2/2-way diaphragm valves have a temperature resistant plastic handwheel and are manually operated. The GEMÜ 602 valve has a stainless steel handwheel and is manually operated. Bonnet and internals are made all of stainless steel. A seal adjuster to increase service life of the diaphragm and an integral optical position indicator are included as standard. —Hermetic separation between medium and operator —Optional flow direction and installation position —Long service life of the diaphragm due to patented seal adjuster (US-Pat. 5 377 956) —Valve body also available in multi-port designs (M-block and T-body) or as tank bottom valve body
