Pettinaroli EvoPICV 94F is a diaphragm type pressure independent balancing control valve that comes with a flanged connection and offfers good valve authority to maintain temperature control and power output from the terminal unit using the complete stroke of the valve. It has a maximum design flow limitation that if once set, the 94F maintains design flow regardless of pressure changes in the system. It has a selectable linear or equal percentage control characteristic and comes in extensive sizes from DN50 to DN250. A SMART actuator is included.

Pressure Independent valves are control valves with an automatic balancing function. An in-built pressure controller keeps a constant differential pressure over the control valve, ensuring full authority and automatic flow limitation.
