DN65
Electronic pressure independent control energy valve. Controls the heat transfer, optimises delta T and automatically regulates flow, regardless of pressure fluctuations in the system.
Application
Energy monitoring, thermal power control and ΔT maximisation functions to optimise system efficiency.
Medium: Group 2 liquids.
Description
Electronic pressure independent control energy valve (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.
