บาลานซ์ซิ่ง วาล์ว PICVs : BP50P..BV150P
บาลานซ์ซิ่ง วาว์ลน้ำเย็น PICVs : Pressure Independent control with flanged connections
BV.. valves can be use in heating and cooling systems that require high flows together with an accurate control.
PICVs are 3 device in one:
- Static Flow limiting valves : the flow of the fully open valve can be selected in a range from 30% to 100% by adjusting the dip-switches on the MVE515B and MVE215B actuators
- Glove Valve : the flow can be controlled from 0 up to maximum set flow by moving the valve plug.
- Differential Pressure Controller with the main objective of keeping the pressure drop constant across the valve plug and consequently a flow control not dependent on differential pressure.
BV valves have an equipercentage caracteristic.
