Liquid line solenoid valve

The primary purpose of a solenoid valve in a refrigerant liquid line is to prevent flow into the evaporator during the off cycle. On multiple systems, a solenoid valve may be used in each liquid line leading to the individual evaporators. A liquid line solenoid is just a valve that opens and closes, it has a magnetic coil and depending on whether the valve is normally open or normally closed it opens or closes when the coil is energized. The MOPD is largely determined by the solenoid valve type, but it also depends on the coil that is used.

This factor is not a problem if the valve is used in the liquid line with normal cooling operation. Find great deals on eBay for liquid line solenoid valve.

With this information, the correct valve can be selected from the Selection Tables. For Liquid Line capacity data, see Page and and individual specification pages. For Suction Line capacity data, see capacity tables Page and 7. For Discharge Gas capacity data, see capacity tables Page and 7. All solenoid valves are tested and rated in.

Liquid line solenoid valve products are most popular in Domestic Market, Mid East, and Eastern Asia. In direct-acting solenoid valves, the plunger opens and closes an orifice inside the valve. In pilot-operated valves, the plunger opens and closes a pilot orifice.

The inlet line pressure opens and closes the valve seal. The most common solenoid valve has two ports: an inlet port and an outlet port. Advanced designs may have three or more ports. We also offer a complete line of general service, isolation, pinch, proportional valves, and manifold assemblies for use in medical equipment, analytical instrumentation, and industrial applications.

ASCO Miniature Valve Products are assembled and 1 factory tested in an ISO Class equivalent clean room. To order fully assembled valve with coil. Our solenoid valves set the industry standard for reliability and reduced power consumption, featuring a complete line -up of directional control, proportional and microfluidic valves designed and customize-able for next generation industrial food production, medical equipment, nuclear facilities and other rigorous applications.

Solenoid Enclosures Nominal Fluid Temp. The liquid−line solenoid valve closes when the thermostat demand is satisfied to prevent liquid refrigerant migration. This device is for use in long− line applications. Liquid refrigerant is going to bypass the valve and leak out, which can cause erratic cooling or low-refrigerant level warnings within the system. A faulty solenoid is going to place a burden of operation on the compressor in your system, causing it to work harder and wear out faster.

Liquid solenoid refrigeration valves are found in many commercial and industrial systems. They are used to isolate the refrigerant in the receiver. A solenoid valve with a built-in check valve is designed to replace a liquid line solenoid valve in parallel with a check valve for reverse flow. This valve may be applied in the liquid line of a supermarket case for positive shutoff during pump down control, while allowing full flow in the reverse direction during reverse gas defrost. Liquid Hammer – Industrial solenoid valves, or other liquid line valves, may cause liquid hammer when installed on liquid lines with high liquid velocities.

If this occurs, it can be minimized by the use of larger pipes, (i.e. lower velocities), or a standpipe installed in the piping near the solenoid valve inlet.

When you need to replace a refrigeration solenoid valve , Grainger carries the right one for your system, plus the solenoid coil to match. Regulate your refrigerant with a thermostatic expansion valve , and put in a filter-dryer to keep it in good condition. The liquid line solenoid is wired in series with the box thermostat. The thermostat controls the box temperature. When the thermostat is satisfied it closes the liquid line solenoid which stops the flow of refrigerant.

The 200RB is a pilot-operate 2-way, normally closed valve. RB valves are used for liquid , discharge, or suction gas refrigerant service. A solenoid valve is an electromechanical device in which the solenoid uses an electric current to generate a magnetic field and thereby operate a mechanism which regulates the opening of fluid flow in a valve. The valve may be installed in any position as long as the coil assembly is never lower than the center line of the valve body.

Diagnosing and curing a sick solenoid valve This website requires certain cookies to work and uses other cookies to help you have the best experience.

EVRA valves are supplied complete or as separate components, i. This may cause extrusion of the teflon seat in the disc. Wrap solenoid valve body with wet cloth to prevent distor-tion from heat. Braze solen-oid valve in liquid line within ft (.m) of indoor coil. Remove and discard solenoid valve end caps.

The PARKER refrigeration solenoid valve is compatible with virtually all CFC, HFC, and HCFC refrigerants and blends. Meets a broad range of applications including refrigeration, air conditioning, and freezing. In a normally closed valve , a plunger return spring holds the plunger against the orifice, preventing flow through the valve. When the coil is energize a magnetic field is produce raising the plunger and allowing flow through the valve. False- it consists of a normally closed liquid-line solenoid valve.

The compressor continues to run and will evacuate refrigerant from the solenoid to the compressor, storing it in the condenser and receiver. Hot gas bypass regulator piped direct to the suction line without a liquid. Explosion Proof Process Valves for Hazardous Locations. Air, Water, Liquid : Way Direct Acting Normally Closed.
