Features:
High cycle double piston stainless steel actuator Compact design, the outside diameter of the actuator is the same size as the bonnet flange connecting diaphragm and body Advantages in multiport bodies and manifold valve assemblies Control air connection on the top, away from the process product line Direction of control air connection is mountable in 90° rotations Circumferential, defined sealing angle between process diaphragm and valve body Flexible diaphragm suspension Encapsulated diaphragm Clean and polished exterior design ideal for sterile wash downs
