0-10 Volts DC 2 Port Chilled Water Regulating Valve (SN, SR, SD Units)
For systems with variable speed pumps and water flow, a 2 port control valve can be fitted. The two port valve has a shut
off pressure of 13.6 Barg.
0-10 Volts DC 2 Port Chilled Water Regulating Valve with bypass for auto commissioning (SD Units)
For systems with variable speed pumps and water flow, a 2 port control valve can be fitted The two port valve has a shut
off pressure of 13.6 Barg.
A bypass leg fitted with a further 2 port valve enables auto commissioning.
The auto commissioning shall be enabled by using a differential pressure transducer to maintain balanced water flow
through the bypass. The controller maintains the same pressure drop through the coil and the bypass. A fixed flowrate is
required for this initial commissioning to occure.
