Verified by manufacturer 14 days ago

DN65

Hattersley Variant:

Electronic pressure-independent control energy valve.

Jump to:
+44 (0)1473 277300 Website

Application

Energy monitoring, automatic flow regulation, heat transfer control and delta T optimization.

Medium: Group 2 liquids.

Description

Electronic pressure-independent control energy valve.

E-PICV+ controls the heat transfer, optimizes delta T and automatically regulates flow, regardless of pressure fluctuations in the system, through the use of pressure transducers, temperature sensors and a high-speed actuator. This combination with the addition of Modbus connectivity also allows for energy monitoring and data exchange with the Building Management System (BMS).


Features and benefits:

  • Energy monitoring, thermal power control and ΔT maximisation functions to optimise system efficiency.
  • Precise flow control using integrated pressure transducers.
  • BMS connectivity through Modbus RTU for control and data collection.
  • Configurable control method via Modbus or voltage to suit application.
  • Able to track position, flow and ΔP through feedback signals.
  • Quick and easy maintenance using diagnostic functions and LED behaviour indicating operating status and any errors.
  • Accurate over wide ΔP range to 800 kPa.
  • Class IV leakage.
