PVC-U / PVC-C / PP-H / PVDF Pneumatically actuated 2-way diaphragm valve

 Open the catalog to page 1

The new DK/CP diaphragm valve is particularly suitable for shutting off and regulating abrasive or dirty fluids. The new internal geometry of the body optimises fluid dynamic efficiency by increasing the flow rate and ensuring an optimum linearity of the flow adjustment curve. The DK/CP is extremely compact and very light. PNEUMATICALLY ACTUATED 2-WAY DIAPHRAGM VALVE • Connection system for solvent welding and for threaded and flanged joints • Optimised fluid dynamic design: maximum output flow rate thanks to the optimised efficiency of the fluid dynamics that characterise the new internal...

The new compact and light piston actuator in PP-GR makes the DK/CP the ideal choice for applications requiring very frequent valve operation and a long valve lifetime.

TECHNICAL DATA PRESSURE VARIATION ACCORDING TO TEMPERATURE For water and non-hazardous fluids to which the material is classified as CHEMICALLY RESISTANT. In other cases, a reduction of the nominal pressure PN is required (25 years with safety factor). PRESSURE DROP GRAPH Working temperature Pressure drop The Kv100 flow coefficient is the Q flow of litres per minute of water at a temperature of 20°C that will generate ∆p= 1 bar pressure drop at a certain valve position. The Kv100 values shown in the table are calculated with the valve completely open.
