Belimo has introduced PIFLV TM, a pressure independent fl ow limiter valve specially designed for ON/ OFF cooling zone applications. It is suitable for high ΔT requirements. PIFLV has a large flow rate range (up to 1 Iitre/s), and a clogresistant flow limiter design. It needs low working pressure (20 kPa) to be pressure-independent, and has zero leakage to minimize energy loss. It has a high body pressure rating of PN25. The actuator runs at low power, and the standard quick actuation time is 75/90s with fast running options of 7/15/35s also available.
