4-way reversing valve
The DHF 4-way reversing valve is a critical HVAC component designed to switch refrigerant flow between heating and cooling modes in heat pump air conditioning systems. This model features a durable construction with materials selected for resistance to wear in high-pressure environments. It is engineered for rapid response, enabling seamless transitions in climate control without system lag or energy loss.
Typical industry builds for this category use copper or brass bodies with stainless steel internal components to handle refrigerant pressures up to 3.5 MPa. The valve integrates with standard HVAC piping via solder or flare connections, with typical bore sizes of 16mm to 35mm. It operates within a temperature range of -30°C to 120°C, suitable for both residential and commercial systems. The design meets standard ISO 5149 for refrigerant handling, ensuring compatibility with R410A, R22, and R32 gases.
This valve is primarily used in heat pump systems, VRF units, and split air conditioners where bidirectional refrigerant flow is required. It is sourced by HVAC installers, OEM manufacturers, and maintenance contractors for both new installations and system upgrades. The supplier offers flexible trade terms, including FOB and CIF shipping options, with payment via L/C or T/T. Bulk packaging is available, and the product carries CE and ISO certifications as stated.

Sourcing 4-way reversing valve from Zhejiang Chunhui Intelligent Control Co., Ltd - China Import Guide
Before placing an order, verify the valve’s compatibility with your HVAC system’s refrigerant type and pressure requirements. Confirm whether the supplier provides test certificates for pressure and leak testing, as these are critical for ensuring reliability in demanding applications. Additionally, check if the valve’s bore size and connection type match your piping system to avoid installation issues.
Logistics details such as lead time, Incoterms (FOB or CIF), and packaging should be clarified upfront. The supplier offers both FOB and CIF shipping options, so agree on the preferred terms to align with your budget and risk tolerance. Payment terms are available via L/C or T/T, but confirm the exact process and any associated fees. For bulk orders, discuss packaging to ensure it meets your handling and storage needs.
Quality checks should include visual inspection for defects in the valve body and connections, as well as functional testing to confirm smooth operation. Request documentation for material composition and compliance with ISO 5149 and CE standards. For critical applications, consider third-party inspection to validate performance under real-world conditions. Ensure all certifications and test reports are provided before finalizing the order.
