- High cycle stainless steel piston actuator - Compact design, the outside diameter of the actuator is the same size as the bonnet flange - Advantages in multiport bodies and manifold valve assemblies - Control air connection in flow direction - CDSA sealing concept, see page 32 - Flexible diaphragm suspension - Encapsulated diaphragm - Clean and polished exterior design ideal for sterile wash downs
Control function (Cf.)： Pneumatically operated Fail safe close (NC)：Cf. 1 & 4 Fail safe open (NO)：Cf. 2 & 5 Double acting (DA)：Cf. 3 & 6 Direction Control connection： At Cf. 4, 5 & 6 in flow direction, standard At Cf. 1, 2 & 3, 90° to flow direction Max. working pressure：Unidirectional (delta p = 100%) EPDM diaphragm 8 bar (115 psi) PTFE diaphragm 7 bar (100 psi) Higher working pressure may be achieved with different actuator. Please consult a SED factory representative for working pressure above the indicated maximum.
