HDP88JA Series Float Control Differential Pressure Control

Operation: HDP88JA series float control is amelioration of differential pressure bypass system. Making use of the technology that HDP88JA series differential control can provide two SPDT switch. It is an excellent substitute of traditional imported one, it has two SPDT switch which can compose the upper or lower limit control of differential pressure, so this will reduce the action time of electric by-pass valve and working time of server. Application: HDP88JA series float 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.　　　　　　　　　　　　　　　　 The control is designed for control, if the control is ineffective, it will cause personal injury and property damages. The install worker shall take charge of increase equipment (safety, limit controls), protect more or increase systems (alarm, supervisory systems), when it is out of control, send the alarm.

Specification:
Single pole and double throw (SPDT) switch, full sealed switch.
Easy for installation,
The set point can be determined quickly through the direct-reading scale.
The pressure difference can be changed without moving the cover.
The drive part is made up of stainless steel.
