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.
