Motor Valve

The sealed motorized valve is unique because the main valve seat is directly actuated by a motor unlike pilot operated valves where pressure differential is required to open the valve. The sealed motorized valve requires no pressure drop to operate. The valve is ideal for applications where stem leakage is intolerable. The valve is slow opening and closing which minimizes the potential for velocity shock or "water hammer effect" sometimes experienced with quick opening and closing solenoid valves. Additionally, the modulating effect of the valve allows the controller to "dial in" the load or "mass flow required" and allow the valve to react at a pace that minimizes system imbalances.  Automatic modulation is the key to a smooth operating system that reduces compressor loading and unloading, pump cavitation and "water hammer effect". The motorized valve has many applications beyond high pressure liquid control, current applications include high pressure liquid formation, intermediate to low pressure vessel liquid formation, back pressure regulators for evaporators, ice makers and flooded chillers, liquid injection oil cooling and hot gas feed to evaporators. There are many potential applications once the control logic / input can be realized. A true analogue controlled / direct operated modulating valve will automate systems to run safely and efficiently.
