Pressure switches for LPG/NH3 flow control

Pressure switches are essentially sensors that respond to fluid pressure changes and perform on/off actions on flow according to pre-set switching points. They provide a safety-crucial functionality in power, oil and gas applications such as liquid transfer and pump systems for LPG specifically.

Product description

Pressure switches monitor and control the pressure of liquid or gas within a pre-defined set of parameters. Exceeding the switch-points triggers its on/off functionality to regulate the pressure.
