Type 2031 - 2/2-way diaphragm valve with pneumatic plastic actuator (Type CLASSIC)

Type Description

The externally controlled diaphragm valve Type 2031/2030 consists of a pneumatically operated piston actuator, a diaphragm and a 2-way 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 minimum/maximum stroke limiter can be installed.

Valve body and diaphragm are available in various materials and variants
Wetted surfaces from Ra ≤ 0.38 µm...≤ 1.6 µm (optionally electropolished)
