What Is A Refrigerant Valve?

What Is A Refrigerant Valve

Refrigerant flow controlling is a process of cooling that prevents overflow of refrigerant and ensures an optimal flow of it into the evaporator.

So refrigerant flow controlling gadget is used in suction, discharge, and liquid lines of air conditioners, refrigerators, and other HVAC systems.

It is called a refrigeration valve. It is the best-designed technology to maintain and regulate the rate of liquid refrigerant into the evaporator.

Having a high-quality and durable refrigeration valve from a reliable refrigeration valve manufacturer and supplier is not less important than others air conditioning parts and HVAC parts.

How Does The Refrigeration Valve Work?

There are many refrigeration valves based on their different role and use, and they work differently with different refrigeration unit parts.

Solenoid Refrigeration Valve Working Principle:

Solenoid Refrigeration Valve Working Principle

For a solenoid refrigeration valve, the solenoid coil stimulated it electrically and produced a magnetic field to attract iron.

As a core of the solenoid valve, the iron plunger opens its valve port by attaching a stem and pin.

The solenoid valve close when the plunger falls due to de-energization.

Miracle professionally manufactures and supplies this electrically operated automatic solenoid refrigeration valve by ensuring its durability.

Refrigeration Ball Valve Working Principle:

Refrigeration Ball Valve Working Principle

The refrigeration ball valve uses a metal rotary ball having a bore.

It uses a wrench instead of a handwheel to turn on and off the valve.

By rotating the wrench a quarter, It can be fully open, partially open, and fully close.

The fluid passes freely while the refrigeration valve is in the fully open position.

The PTFE seal in the upper portion of the ball valve is connected to the wrench, which can be rotated 90 degrees around its axis.

Refrigeration Shut Off Valve Working Principle:

Refrigeration Shut Off Valve Working Principle

The refrigeration shut-off valve owns a spring, hook, diaphragm, and valve.

When it’s is closed, it should be manually reset or turned on.

It is controlled by a latch mechanism and linked to the spring and diaphragm above.

The gas enters by inlet and out by the outlet through the lower chamber.

The impulse line senses the pressure under the diaphragm, and it lifts the spring upwards when the pressure increases.

Refrigeration Check Valve Working Principle:

Refrigeration Check Valve Working Principle

The inlet and outlet anchorage of a refrigeration check valve relies on the compressor’s refrigerant pressure.

As an automated electric valve, the refrigeration check valve controls the stability of the raised and low pressure of the compressor.

It turns the valve off to stop the refrigerant flow when it reaches balance.

So the compressor stops working, and the backflow in the refrigeration system can be prevented.

After the restarts of ac or refrigeration system, it starts working again.

Refrigeration Valve And System

Refrigeration Valve And System

Refrigeration valves are used with many parts of the refrigeration and air conditioning system to maintain the refrigerant pressures between the evaporator and the condenser and regulate the flow of refrigerant that enters into the evaporators.

Such as refrigeration check valve, refrigeration expansion valve, refrigeration shut off valve, refrigeration ball valve, 4-way reversing refrigeration valve, roto lock refrigeration valve, refrigeration solenoid valve, etc.

We manufacture and supply the most reliable and strongest refrigeration valves and systems to regulate the refrigerant movement in your ac and refrigerations.

You will find the most suitable refrigeration valve types from our large collection for sale, which will fit your wide range of temperatures.

As a part of our plenty variants of the refrigeration valve system, the refrigeration valve for the compressor is a phenomenon.

For any hermetic or semi-hermetic or scroll compressor, we manufacture and supply the best alternative.

Miracle is the first choice of thousands of people worldwide and wholesalers who use different valves for their AC, split system, heat pump, refrigeration, repairing, charging, or replacement.

Expansion Valve

Application of Refrigeration Expansion Valve in Refrigeration System
Application of Refrigeration Expansion Valve in Refrigeration System

The expansion valve is designed for food cold chain, cold room condensing unit, home, and commercial air conditioning field.

It’s the main part of a refrigeration system, as important as compressors, evaporators, and condensers.

It should be installed between the evaporator and condenser, the outlet of the expansion valve connects the inlet of the evaporator.

It should be installed near the evaporator, as you can see in the above pic.

The main function of the expansion valve is to keep the overheating degree of the evaporator outlet at a certain level.

Miracle expansion valve is suitable for refrigerants such as R134a, R22, R404, R502, and R410a.

Of course, there are also richer types, such as

The refrigeration solenoid valve has two types, directly operate type solenoid valve and servo operate solenoid valve.

It is designed for liquid line, suction line, and hot gas line of freezing, refrigeration, and air conditioning equipment.

A solenoid valve should be installed between the condenser and expansion valve.

Its main function is to cut off the system when the compressor stops working, to avoid the liquid hitting situation when the compressor restarts and is also useful for changing the direction of cooling and heating.

It is widely used for an HVAC&R system.

Miracle can supply you Danfoss type solenoid valve, one-way flow, suitable for all the HCFC, HFC refrigerants, it has a normal open and normal close type for different using demand.

You can choose different voltage and frequency solenoid valve coils according to your market and system, such as AC 220v/50hz,220v/60hz,110v/60hz, DC 12V, DC24V.

The unloading solenoid valve is an automatically loaded valve, it will be loaded according to the heat load situation of the system.

It also has a normal open and normal close type for your reference.

The coil has AC and DC to meet your requirements, its max working pressure is 30 bar, suitable for all the refrigerants.

R410 Solenoid valve is specially designed for R410a, but you can also use it for common refrigerants.

Its max working pressure can reach 45BAR, the applicable temperature can be -40℃ to 105℃.

Castel solenoid valve is the diaphragm type solenoid valve, it is used to replace the Castel brand solenoid valve, suitable for all the common refrigerants, its max working pressure reaches 3MPA.

Refrigeration Ball Valve

Application of Refrigeration Ball Valve in Refrigeration System

When filling the refrigerant with the system, add refrigeration oil, replacing the filter drier or expansion valve.

You all need a ball valve to control the opening and closing of the refrigeration system.

You can install ball valves at the inlet and outlet of the filter drier, suction accumulator, and oil separator.

Disconnect the refrigeration system by closing the ball valves to replace these refrigeration components.

When the replacement is complete, open the ball valve to reopen the entire system.

Refrigeration Shut Off Valves

The diaphragm hand valve is a one-way manual shut-off valve.

Will be installed on the liquid, gas.

And suction pipeline of the system to divide the liquid flow area from the spindle chamber.

Refrigerant Check Valve

Magnetic check valve adopts magnetic diaphragm design, metal sealing, inner use guide device, and self-absorbing structure design.

Therefore make sure the installation angle of the check valve has no limit, also ensure it won’t be affected by the reverse pressure.

The check valve can be closed automatically, which makes the reverse direction almost zero leakage.

It is suitable for big and medium refrigeration equipment and air conditioning devices.

And it should be installed at the exhaust pipeline of the compressor for controlling the flow direction of refrigerant, to achieve the cooling and heating function.

Rotalock Valve

The main function of the rotalock valve is adjusting the flow volume of the refrigerant and opening/closing the flow of the refrigerant.

Its function is controlled by the rotating parts of the rotalock valve.

We normally equip the rotalock valve as the standard parts for the liquid receiver.
