Belimo pressure independent control valves stabilize variable flowhydronic systems for a lifetime of efficiency and worry-free, dynamicbalancing.
Belimo pressure independent valves directly control the water flowrequired by the coil and are not affected by pressure fluctuations inthe system. The valves are selected based on the flow requirementsof the coil, and no valve authority and Cv calculations are needed. Byprecisely controlling the flow, the pressure independent valveseliminate the need for balancing valves, thus reducing installationcost. The biggest benefit comes in the form of energy savings byeliminating overflow through the coil. Overflow wastes pumpingenergy and is the main cause of low Delta T syndrome in chilled watersystems.
Belimo pressure independent valve technology maximizes energy savings of variable flow pumping systems while addressing unique control challenges. Belimo offers a series of pressure independent (PI) control valves; from the PIQCV, a super compact PI valve, ePIV an electronic PI valve offering true flow measurement to the Energy Valve that optimizes, documents and proves water coil performance.
With Belimo pressure independent technology, every system performsto its full potential – saving time, money, and other precious resources.
With Belimo’s pressure independent control valve technology only a single valve is required to maintain proper flow through each circuit. Each valve arrives from the factory with a flow setting that can be changed in the field, so there is no additional balancing required. The system performs perfectly from start-up. If a facility adds new circuits because of an expansion, the flow control of existing circuits remains intact eliminating the need for re-balancing the system.

Belimo’s pressure independent valves precisely control the water flow required by the coil and are not affected by pressure fluctuations in the system.
Pressure independent control valves maximize energy savings by dynamically balancing the load under all conditions eliminating overflow of the coil thus reducing pumping costs.
Belimo ball valve design offers zero leakage and eliminates energy loss while ensuring reliable operation throughout the entire life of the valve.
