The externally controlled diaphragm valve Type 2033 consists of a pneumatically

operated piston actuator, a diaphragm and a tank bottom valve body.

The proven and robust 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

valve body and the diaphragm are available in all common materials and

variants. The actuator has a compact, autoclavable design (PPS variant). The

integration of the automation units 8690/8697 is possible in all configuration

levels (can be retrofitted). An explosion-proof ATEX / IECEx device variant is

available.

The add-on body is optionally available in plastic or stainless steel. The actuator

is equipped with an integrated, optical position indicator as standard,

optionally a min./max. stroke limiter can be installed.
