Used in pharmaceutical, biotech, food and beverage, and other high-purity process applications, the GEMÜ 687 is a 2/2-way pneumatically operated diaphragm valve featuring a low-maintenance plastic membrane actuator with metal distance piece and stainless steel valve body. The 687 series employs hermetic separation between the actuator and the wetted fluid path, making it suitable for corrosive, abrasive, and high-purity media. Published GEMÜ specifications list an operating pressure range of 0 to 10 bar (0 to 145 PSI) and a media temperature range of -10 to 100 degrees C, with sterilization capability up to 150 degrees C for CIP/SIP processes. Normally Closed, Normally Open, and Double Acting control functions are available within the 687 series. The valve body is compatible with multiple connection standards including DIN, ISO, ASME, and SMS. GEMÜ products are recognized in sanitary and process industries for conformance with 3A, FDA, and EHEDG standards. The full configuration code was not legible from available photos; buyers should verify the valve size, connection type, body material, and diaphragm material against their application requirements before purchase. GEMÜ brand is confirmed by visible marking on the actuator cap.
