WebAn easier delta-T solution. Siemens pressure independent control valves have the unique advantage of always maintaining their full stroke, regardless of the maximum adjustable flow setting, to provide better control. This significantly reduces or eliminates hunting for the right actuator setting, resulting in better control and increased comfort.

WebMoreover, it is self-powered (self-operating) and does not burden or interact with the building automation control system. With pressure independence, the amount of water flowing through the controlled load (e.g. heat exchanger coil) is more accurate. It is only a function of the control signal, and is less WebThe DPCV diaphragm will regulate to control ΔpC (differential pressure across the circuit) depending on pressure impulse from the supply side and direct pressure from the return side. The spring force will equal the ΔpC. In all FlowCon DPCVs the diaphragm will be a rolling diaphragm which will result in a very compact valve design.
WebQ.02 What is the difference between a PICV and a PICCV? Some manufacturers claim their valve is pressure independent if it controls flow. A truly pressure independent valve controls flow and has a pressure independent control characteristic. The Hattersley PICV is fully pressure independent. WebI do not understand what balance you are looking for? If the control valve and its controller are not in balance, the control valve will either go to the wide-open position and stay there, or it will stay closed and act as though it is not responding. This situation can normally be corrected by reversing the action of the controller. For this ...
