Refrigeration service valve diagram
Many refrigeration compressors incorporate a suction service valve and a discharge service valve. These are used to allow refrigeration gauges to be attached to the system; and, if needed, they are used to isolate the compressor from the rest of the system. Working with these valves is not difficult, but there are some finer points to remember. Often, the refrigeration equipment is still running, but the product temperature is suffering about 7-10°F. A suction service valve and a dis-charge service valve are located on the compressor. A service valve called the king valve is mounted on the outlet of the re-ceiver. These service valves are equipped with a gauge service port. 1 A solenoid is a simple form of an electromagnet consisting of a coil of insulated copper wire. A solenoid valveis an electromechanical valve frequently used to control the flow of liquid or gas. Definitions Solenoid valves are found in many applications and are commonly used in refrigeration and air conditioning systems.

Installing Service Piercing Valves Line tap valves can be used to access the refrigeration system. Line tap valves should be temporarily placed on the suction and liquid process tubes. Leaving valves on the system may void warranty. IMPORTANT: Never leave piercing valves of any type on an R-290 refrigeration system. Accessing Refrigeration System Valves are usually made of spring steel and designed to make a tight seal until the pumping action of the piston opens them. The mating surfaces of valves must be perfectly flat, and defects as small as 0.001 in. (0.0254 mm) can cause unacceptable leaks. In service, the valve must open about 0.010 in. (0.254 mm).

EDITION 3/99 DATE 6/07 ... such as a thermostatic expansion valve, low-side float valve or high-side float valve, and make sure that column will stay at a reasonable working temperature. Any flashing of liquid refrigerant in the liquid line affects the capacity of flow-control devices and of the evaporator. A small wrench with a ratchet called a refrigeration service wrench is used to open and close this valve. On most semi-hermetic compressors this type of valve is used as the service valve and king valve on the receiver. Some versions of this valve require an Allen wrench, instead of a service wrench, for adjustment. The most common service valve used on small equipment is the Schraeder valve. This valve is pictured in Fig. 26-4 and is very familiar to all for it is used on both the low and high sides of the refrigeration system. Located in the hoses of your service manifolds are indenters. These push the core of the Schraeder valve open when the '/4 ...
15. Refrigeration system: Hot gas Bypass valve. Hot gas bypass valves used in compressors do not have a capacity reduction device like compressor unloader. Bypass valve regulates the cooling capacity by injecting discharge gas back into the suction. It keeps the evaporator pressure constant regardless of the load. refrigeration systems that have been the mainstay in the industrial sector and emphasize unique characteristics that differentiate ammonia systems from traditional halocarbon refrigeration systems. An emphasis will be placed on safety. ... King valve DX (automatic) Evaporative The Parker Refrigeration Valves consist of a family of direct and pilot operated solenoid valves for liquid, suction and hot gas defrost application requirements. The valves are compatible with virtually all of today's commercially available CFC, HCFC and HFC refriger-ants and blends. The Parker refrigeration valves meet manual stem service valves.A suction service valve and a dis-charge service valve are located on the compressor. A service valve called the king valve is mounted on the outlet of the re-ceiver. These service valves are equipped with a gauge service port.Operating refrigerant pressures may be observed on the

The second automatic valve is a much different type of device. It is a servo-operated valve. By that we mean it's position is controlled by the pressure of gas admitted to a chamber beneath a diaphragm that drives the valve disk open and closed. More pressure under the diaphragm closes the valve and less pressure opens it. SeRvO pReSSURe ...
