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

    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.

    • Valve housing and diaphragm available in various materials and designs
    • Surfaces in contact with the product from Ra ≤ 0.38 µm...1.6 µm (optionally electropolished)
    • Available in all common connection sizes and variants
