Energy Efficiency Zone Application- PIFLV is a pressure independent flow limiter valve that is specially designed for ON/OFF cooling zone applications. It is the best fitting solution where large delta T is required.
Large flow rate range, covers up to 1 I/s
Clog-resistant flow limiter design
Low working pressure 20kPa to be pressure independent
Zero leakage minimizes energy loss
High body pressure rating PN25
Actuator runs at low power
Quick actuation 75s/90s as standard, fast running options: 7s/15s/35s available.
Innovative Flow Limiter Design
The unique design combines an ultra-slim flow limiter with a two-way ball valve supply a specific flow regardless of system pressure fluctuations. It ensures the right flow across the valve without overflow.
This new design provides much greater flow capacity since the flow rate is no longer bound by the complex cartridge or regulator limits. The clean and spacious inner structure allows dirt to wash our easily without clogging.
Actuator with Patented Brushless DC Motor saves Energy
The brushless DC Motor’s power consumption when running is a mere 0.3 W (0.15 W when holding) saving energy and transformer power. In addition to significantly reducing energy costs, this helps eliminate failures due to stalled motors and prolongs actuator life. It also allows for more units to be powered by a single transformer.
