The externally controlled diaphragm valves, Type 2730 and 2731, consist 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 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.
