The externally controlled diaphragm valve, Type 2730, consists of a pneumatically operated piston actuator, a built-in positioner, a diaphragm and a 2 way valve housing.

The proven and robust actuator with plastic housing ensures use under hygienic or aggressive environmental conditions. The flow-efficient valve housing with little dead space enables high flow rates and a wide range of possible uses. The plastic valve housing and the diaphragm are available in all common materials and designs. The actuator has a compact, autoclavable design (PPS version).

The integration of automation TopControl units 8692/8693/8694 and SideControl units 8635/8792/8793 is possible in all expansion stages (can be retrofitted). An explosion-proof ATEX / IECEx device variant is available.The add-on housing is available in plastic or stainless steel.

The actuator is equipped with an integrated, optical position indicator as standard, optionally a min./max. stroke limitation can be installed.
