Differential Pressure Controller with SPDT Contact for Air
Condition
SKDP88 differential pressure control is normally used in gas or
liquid system to control the pressure difference between the
gas/liquid pipeline and the circuit. A typical application is to
install the controller in the bypass pipeline near the system pump.
When the system pressure difference increases and exceeds pre-set
pressure, the control valve will open and more liquid/gas 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.
Performance
The set point can be determined quickly through the direct-reading
scale.
The pressure difference setting can be changed without moving the
cover.
