DN65
Pressure-independent control valve (PICV) using pressure transducers combined with a high-speed actuator to automatically regulate flow, regardless of pressure fluctuations in the system.
Application
Flow regulation.
Medium: Group 2 liquids.
Description
Pressure-independent control valve (PICV) using pressure transducers combined with a high-speed actuator to automatically regulate flow, regardless of pressure fluctuations in the system.
Features and benefits:
- Reduced commissioning time and costs due to the preconfigured actuator settings, via the Building Management System (BMS) or Hattersley configurator tool.
- Stable head output by maintaining a flow rate regardless of ∆P via pressure sensors.
- System optimisation using the indicated flow rate and position feedback via Modbus.
- Reduced installation labour and cabling costs due to daisy chaining between Modbus actuators.
- Reduced downtime due to error feedback via the BMS.
- Optimized system efficiency and user comfort due to fast responding actuator.
- Isolation function with Class IV leakage up to 800 kPa.
