Differential pressure control is normally used in water system of central air-condition to control the pressure differential between the pipe of water providing & the pipe of water returning. It is different from other pressure differential control, which has a SPDT contact. Through the movement of the floating contact, the control reaches the contact and makes the engine driver to operate the valve. A typical sample of application is to equip the valve in the side pipe near. The system water pump. When the pressure differential between the pipe of water providing & the pipe of water returning is over the pre-set pressure, the valve will open wide, more water goes through the side valve, which will reduce the pressure differential between these two pipes of the water system. On the opposite, the pressure differential will increase between these two pipes of the water system.
@ For use with fluorinated refrigerants as well as with air and liquid; (Allowable fluid temp.: -45º C~+120º C)
@ Differential pressure of the pressure control is asdjustalbe;
@ Novel micro-switch ensures reliable switching;
@ Agile mounting bracket is suitable for different occasions
@ It can be used at water system. Reaching to a constant rate of flow through the control of the differential pressure between in & out pipes.
@ The differential pressure control can be used as protective devices for maintaining oil pressure of compressor for air-conditioning purpose.
@ The differential pressure have two pattern: Without time setting differential pressure control(frozen water) and with time setting differential pressure control(oil protective);
@ Max working pressure is 33bar., It is can used as protective the oil filter drier.
@ Please make it clear to us when ordering if the system adopts the media corrosive to phosphor and bronze, suitable models will be recommended;
@ Our products can substitute for congeneric import products, such as JOHNSON\DANFOSS\SAGINOMIYA\3S\RANCO and so on.
