Description

Adjustable Pressure Switch, Differential Pressure Controller for Water

Description

QYD 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.

QYD series differential pressure controls is designed to prove flow through pumps

Renovated SPDT micro-switch ensure the reliable switch function

Used in fluoridated refrigerant,but also in air and liquid(-20 to 120°C)

Flexible mounting bracket suits various kinds of application

Various connections are available on request
