Type 2731 - 2/2-way – diaphragm valve with pneumatic position-actuator in plastic ( Type Classic )

The depiction of the products may differ from the actual specific design.

Please consider the technical attributes and Data Sheets.

Type Description

The externally controlled diaphragm valve type 2731 consists of a pneumatically operated piston actuator, a bult-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 enable 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 units Top Control 8692/8693/8694 Side Control 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 optionally 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.
