The pneumatically operated diaphragm valve GEMÜ D41 is designed for use in sterile applications. The diaphragm hermetically separates the actuator from the working medium. The valve GEMÜ D41 with EasyLock technology is mounted entirely without loose components using a central gearbox. All actuator parts (except the seals and design elements) are made from stainless steel. The “Normally closed”, “Normally open” and “Double acting” control functions are available.
