check valve

The one-way valve conducts in the forward direction and intercepts in the reverse direction, and is only used in the heating process of air conditioning. The one-way valve does not work in the cooling process. The purpose of heating is to increase the flow resistance of the refrigerant, reduce the flow velocity of the refrigerant, fully evaporate the refrigerant in the outdoor unit, and turn the refrigerant gas discharged by the compressor into refrigerant liquid, thereby improving the heating effect of the air conditioner.

Applicable scope
Active refrigerants: R22, R1348, R407C, R410A, R32; Maximum working pressure: 4.2MP; operating efficiency: -30C -+120C; Applicable environmental relative humidity: below 95% RH
structural type

Feature Overview
Unidirectional forward conduction and reverse flow interception are only used in the heating process of air conditioning. Unidirectional conduction does not work in refrigeration. Its function during heating is to increase the flow resistance of refrigerant, reduce the flow velocity of refrigerant, and allow the refrigerant to fully release in the outdoor unit, thereby discharging the compressor
The gas before refrigeration is converted into refrigerant liquid, which improves the heating effect of the air conditioner,
Product Features
Small valve body diameter; The integrated structure eliminates leakage; Reliable performance and long lifespan:
