GEMÜ 651 2/2-way aseptic diaphragm valve

Description

The GEMÜ 651 piston actuated 2/2-way diaphragm valve has a stainless steel piston actuator and is pneumatically operated. It is designed for use in sterile applications.

The GEMÜ 651 piston actuated 2/2-way diaphragm valve has a fully integrated automation module and an internal air supply. Normally closed (NC) and Normally open (NO) control functions are available. The automation module is available in two versions. Either as a combi switchbox with integrated 3/2-way pilot valve for valve actuation and position feedback or with an integrated electro-pneumatic positioner.

The GEMÜ 651 piston actuated 2/2-way diaphragm valve has a controlled microprocessor, intelligent position sensor as well as an integrated analogue travel sensor system. The Speed-AP function simplifies commissioning. The base of the actuator housing is made of stainless steel, the cover is made of a stable transparent plastic material.
