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.

Product Introduction

The Sanhua SHF-35B-67G48 Stainless Steel Four-Way Reversing Valve is an optimized model within the 35B series, designed for medium-temperature microfluidic applications. Its key differentiation lies in the 67-series medium-temperature adaptation combined with the precision of the G48 interface, making it ideal for compact high-temperature experimental devices, micro-heating systems, and other precision scenarios that demand stable control under mid-temperature conditions.

Key Specifications

Part of the 35B series, this valve operates within a pressure range of 0.5–3.0 MPa and a temperature range of 20°C to 120°C (medium-temperature adaptation zone).
It features a G48 interface (ISO 228 standard micro internal thread), suitable for DN20 pipelines, with a recommended flow rate of 5–12 m³/h.
Compared with the 79G48 model, the 67G48 has an increased maximum operating temperature by 20°C, utilizing high-temperature-resistant sealing components to ensure reliable performance in medium-temperature fluid systems.

Technical Advantages & Innovations

  • Upgraded medium-temperature sealing structure using fluoroelastomer (FKM) seals, achieving over 60,000 switching cycles at 120°C operating temperature.

  • Optimized thermal conductivity design minimizes heat transfer from the working medium to the control module, maintaining stable precision even in elevated temperatures.

  • The 304 stainless steel body undergoes high-temperature passivation treatment, improving corrosion resistance by 30% in humid, mid-temperature environments.

Typical Application Scenarios

  • Compact high-temperature fluid testing equipment – Used for material thermal performance testing systems, providing reliable flow redirection within the required medium-temperature range.

  • Micro heating systems – Such as small-scale industrial ovens or air-heating loops, where the G48 interface ensures stable switching and uniform heat distribution.

  • Auxiliary systems for miniature steam generators – Enables precise redirection of micro steam flow, with temperature-resistant sealing preventing leakage in high-humidity conditions.

Installation & Compatibility Notes

  • Confirm that the system operating temperature remains within 20°C–120°C to prevent over-temperature damage.

  • Use high-temperature sealing gaskets at the interface to enhance sealing performance under medium-temperature conditions.

  • During commissioning, increase temperature gradually while monitoring the valve’s switching response, and record performance parameters at different temperature levels for calibration.
