Solenoid Valves Manufacturer,Supplier and Exporter in India
Product Code : EL-RACLE-12841
Jlab Export is a leading Solenoid Valves Manufacturer,and suppliers in India
Made for the gas side of a refrigeration circuit, this solenoid valve controls refrigerant vapour rather than liquid. A coil on top moves a plunger inside the body, so a thermostat, timer or pressure control can open or shut a vapour line by an electrical signal. Gas-side valves are used on hot gas lines from the compressor discharge and on suction lines.

Lab Exercises on Gas-Line Valves
Students start on the circuit diagram. They mark where a gas-side valve can sit, on a hot gas line or a suction line. Then they compare that with the liquid-line position of the liquid-side Solenoid Valves model. The sectioned solenoid valve in the Eight Piece Sectioned Valve Set For Demonstration then shows them the plunger, seat and port inside.
For the electrical check, they read the coil resistance with a Digital Multimeter and write the value in their job sheet. On a running rig they fit Manifold Gauges For Refrigeration Systems to the service ports. They then switch the coil and watch the suction pressure as the vapour line opens or closes.
Frequently Asked Questions
What does gas side mean on this valve?
It means the valve is meant for refrigerant vapour. Typical gas-side duties are hot gas lines leaving the compressor, for hot gas bypass or hot gas defrost, and suction lines. A liquid line takes the liquid-side model instead.
Can a liquid-line solenoid valve be used on a gas line?
It is better not to. For the same flow of refrigerant, vapour takes up far more volume than liquid. A valve sized for a liquid line can then be too small for a gas line and cause a large pressure drop. Choose the valve for the line it will sit in.
Why does a solenoid valve hum or buzz?
A soft hum from an AC coil is normal. A loud buzz often means the supply voltage is low, the coil is loose on its tube, or dirt is stopping the plunger from seating fully. Check the voltage at the coil terminals first.
How should the valve be brazed into a line?
Take the coil off before brazing, wrap the valve body in a wet cloth and keep the flame on the joint, not on the body. A small flow of nitrogen through the pipe while brazing stops oxide scale forming inside. Refit the coil once the body has cooled.
