Introduction

Solenoid valves are used in refrigeration and air-conditioning to stop, interrupt or divert the flow of refrigerant. They operate by opening or closing the orifice directly or by pilot (Servo) operation. An electro magnetic coil is used to open the valve when it is energised.

Heldon’s New Style Solenoid valves are made from brass forgings and are available with extended copper or male SAE connections. A special diaphragm material is used for an extended service life, to be compatible with most fluorinated refrigerant and oil combinations.

These new style valves are matched to a range of “click-on” style coils, which, when installed with the supplied Hirschmann plug and o-ring, offer an IP65 rating. Another feature of these is the built-in LED, indicating power supply to the coil.
