Differential PRESSURE CONTROL
Porduct 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 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
rduce the pressure differential between these two pipes of the water
system.On the oppsite,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: -45< C~+120< C
@ Differential pressure of the pressure control is adjustalbe
@ 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
