BURKERT 348713 Type 2032 is an externally controlled diaphragm valve consisting of a pneumatically operated piston actuator, a diaphragm, and a T-valve body. The actuator with a plastic housing ensures use in hygienic or aggressive ambient conditions. The flow-efficient valve bodies with little dead space enable high flow rates and a wide range of possible uses. The actuator has a compact, autoclavable design (PPS variant).
