| Note: 1.ΔP represents the pressure drop from ØC to ØS or from ØE to ØS; 2. The selection capacity of the four-way valve for R32 systems should be ≥60%. It is not recommended to use the four-way valve in systems with a capacity less than 60% of the nominal capacity. When used in R32 systems, it is essential to ensure the reliability of low-pressure commutation under extreme conditions. |

Compared with the “-05” and “-06” models in the same series, this valve is optimized for the low-pressure range, has a simplified structure, and reduces cost by 20%.
Technical Advantages & Innovations:
-
Simple medium-temperature low-pressure seal structure, balancing cost and basic sealing requirements, with a seal life exceeding 40,000 cycles.
-
Lightweight valve body design, weighing only 0.7 kg, improving installation convenience by 30%.
-
High component interchangeability reduces future maintenance costs.
Target Applications:
-
Small Residential Medium-Temperature Equipment: Such as steam switching in small home saunas, meeting residential medium-temperature low-pressure needs.
-
Light Industrial Medium-Temperature Fluid Systems: Switching medium-temperature cooling media for small motors, meeting basic equipment heat dissipation requirements.
-
Small Greenhouse Heating Systems: Controls the direction of hot water or steam supply, suitable for medium-temperature low-pressure greenhouse operation.
Installation & Compatibility Notes:
-
Ensure system pressure is within 0.3–2.0 MPa to avoid overpressure.
-
Install the valve body away from flammable materials to prevent medium-temperature safety hazards.
-
During commissioning, focus on checking seal performance under medium-temperature low-pressure conditions and periodically clean the valve body.
