The externally controlled diaphragm valve, Type 2063, consists of a pneumatically operated stainless steel piston actuator, a diaphragm and a 2-way body. The proven and robust actuator with stainless steel valve body 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 valve body and the diaphragm are available in all common materials and variants. The actuator has a compact, autoclavable design with a large stainless steel body, high temperature resistance and gap-free seals. The integration of the automation units Type 8697 is possible in all expansion stages (can be retrofitted). The actuator is provided with an integrated, optical position indicator as standard.
