PIFLV is a pressure independent flow limiter valve specially designed for ON/OFF cooling zone applications. It is suitable for applications where large ΔT is required.
PIFLV has a large flow rate range (up to 1 L/s), is clog-resistant, has a low working pressure of 20 kPa to be pressure independent, has zero leakage, and has a high body pressure rating of PN25. The actuator runs at low power, and quick actuation in 75s/90s is standard. The design combines an ultra-slim flow limiter with a two-way ball valve
to supply a specific flow regardless of system pressure fluctuations. It ensures the right flow across the valve without overflow. This design provides high flow capacity, since the flow rate is not bound by the complex cartridge or regulator limits. The clean and spacious inner structure allows dirt to wash out easily without clogging.

The brushless DC motor has a low power consumption of 0.3 W (0.15 W when holding), saving energy and transformer power. It helps eliminate failures due to stalled motors, and prolongs actuator life. It also allows for more units to be powered by a single transformer.
