The externally controlled diaphragm valve Type 2730 consists of a pneumatically operated piston actuator, a built-in positioner, a diaphragm and a 2-way valve body. The proven and robust actuator with plastic housing ensures use under hygienic or aggressive environmental conditions. The flow-efficient valve body with little dead space enables high flow rates and a wide range of possible uses. The plastic valve body 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 Type 8692/8693/8694 and SideCONTROL units Type 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 minimum/maximum stroke limitation can be installed.
