Diaphragm Valves
DV14
Pneumatically Operated Valve DN 8-20 mm (3/8"-3/4")
Features
•
efficient thermoplastic piston actuator direct assembled with
the valve body
•
control air connection 90° to flow direction for side by side or
other installations saving space
•
compact design, the outside diameter of the actuator is the
same size as the bonnet flange
•
actuator high resistance to heat transfer
