What is the Purpose of Check Valves in a Refrigeration and Air Conditioner System?
What are the Types of Refrigeration Check Valves?
How does a refrigeration check valve work?
You can find everything from “Refrigeration Check Valve-A Complete Guide“
The Refrigeration Check Valve adopts a whole copper tube, and the two ends of the copper tube adopt a special process to shrink the neck into a tube.
Therefore, it does not require the welding process of the traditional brass valve body. It is safe and leak-free.
At the same time, the refrigeration check valve is integrated with molding processing, more convenient for your use.
Refrigeration Check Valve uses AlNiCo Permanent Magnets
Magnetic Check Valve diaphragm traction is made of high-strength permanent magnet material Al-Ni-Co.
Al-Ni-Co has the advantages of not being easy to rust, strong suction, etc., which ensures the longer service life of the magnetic check valve, even if the magnetic check valve is installed at an uneven level.
Miracle refrigeration check valve has successively passed ISO9001: 2000 quality management system certification, American UL product safety certification, EU CE product safety certification, and EU RoHS environmental protection certification.

3142 Refrigeration Check Valve
The 3122 series refrigeration check valve can be used in commercial refrigeration systems. It can be installed in the liquid line of the refrigeration system.
3122/3142 series refrigeration check valve adopts the design concept of valve stem self-closing and sealing. For the 3122/3142 series parameter, please contact us now.
YCV Refrigeration Check Valve
YCV refrigeration check valve is a piston check valve, mainly composed of the valve body, piston, copper extension tube, gasket, O-ring, spring, etc.
It allows the medium working temperature range to be -50°C~+140°C.
The maximum testing pressure of the YCV refrigeration check valve can reach 3.5MPa.
Differential Oil Flow Check Valve
The Differential Oil Flow Check Valve is installed in the oil circuit of the refrigeration and air conditioning system.
It can be installed on an oil separator and an oil reservoir. Miracle differential oil flow check valve is commonly used for Sporlan, Danfoss, Parker, Mueller, and other brands. Contact the Miracle now to learn more about the advantages of differential check valves.
NRV Refrigeration Check Valve with Thread and Welding
The NRV refrigeration check valve is a direct-flow check valve.
In the refrigeration system, the refrigeration check valve needs to be designed in a different structure due to the structure of the refrigeration system.
The threaded connection(SAE) structure can realize the connection of the NRV refrigeration check valve more quickly, does not require fire welding, and will not harm other parts of the refrigeration system.
The advantage of the ODF connection is affordability and versatility.
NRVH 90° Angle Refrigeration Check Valve
The NRVH refrigeration check valve is a straight-angle check valve. The NRVH refrigeration check valve can be used in the refrigeration unit’s liquid suction and hot gas pipelines, and air conditioning devices with fluoride refrigerants.
The NRVH refrigeration check valve has a built-in damping piston, so that the NRVH refrigeration check valve can be installed in places with pressure pulses, such as the exhaust pipe of a compressor, and can also be used in a parallel compressor system. We are waiting for your inquiry!
Float Series Refrigeration Check Valve
The float series refrigeration check valve adopts an integrated structure design inside to eliminate the possibility of leakage. The float series refrigeration check valve adopts a PTFE design and a unique structural design, which increases the life of the float series refrigeration check valve by 2 times.
Refrigeration Magnetic Check Valve
The MCV refrigeration check valve is designed with a magnetic diaphragm inside and a filter. It can be connected in one direction at the same time to effectively filter impurities in the system.
The advantage of the MCV refrigeration check valve is better sealing and almost zero leakage in the reverse direction. Contact us to get a refrigeration check valve now!
