Product Introduction
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 controls, 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 wide open, 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: -10° C~+100° C
Differential pressure of the pressure control is adjustable
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 pipe
Please make it clear to us when ordering if the system adopts the media corrosive to phosphor and bronze, suitable models will be recommended
