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-67G49 Stainless Steel Four-Way Reversing Valve is a specialized model within the 35B series, designed specifically for medium-temperature, high-pressure microfluidic systems. Its key distinction lies in the G49 high-pressure interface combined with the 67-series medium-temperature adaptation, making it ideal for micro high-pressure reactors, compact high-pressure fluid systems, and other precision environments requiring simultaneous pressure and temperature stability.

Key Specifications

As part of the 35B series, this valve operates within a pressure range of 0.8–4.0 MPa (high-pressure adaptation zone) and a temperature range of 20°C–120°C.
It features a G49 interface (ISO 228 standard high-pressure micro internal thread), suitable for DN20 pipelines, with a recommended flow rate of 6–14 m³/h.
Compared to the 67G48 model, the maximum working pressure has been increased by 1.0 MPa, while the threaded interface adopts a reinforced high-pressure design, improving compressive strength by 25%.

Technical Advantages & Innovations

  • Hybrid medium-temperature and high-pressure sealing system, combining metallic and fluoroelastomer materials, enabling a sealing pressure capacity of up to 5.0 MPa with a leakage rate ≤0.01 L/min under combined pressure and temperature conditions.

  • Enhanced internal flow-path erosion resistance, reducing wear caused by high-pressure media and extending overall service life.

  • Integrated pressure buffering device minimizes directional switching impact during simultaneous temperature and pressure operation, ensuring stable performance in demanding environments.

Typical Application Scenarios

  • Micro high-pressure reactors – Controls switching of high-pressure reaction media in small-scale chemical applications, ensuring reliability under medium-temperature, high-pressure conditions.

  • Compact medium-temperature, high-pressure cleaning equipment – Used for precision part cleaning systems where both pressure and temperature stability are critical for effective performance.

  • Micro energy testing systems – Such as small fuel cell evaluation units, providing precise direction control of high-pressure test media to ensure reliable and repeatable data collection.

Installation & Compatibility Notes

  • Use dedicated high-pressure tools to secure the interface during installation to ensure proper sealing.

  • Mount the valve within a protected high-pressure area to minimize potential leakage risks.

  • During commissioning, strictly follow the “low-pressure heating → gradual pressurization” procedure to verify stable switching performance under combined pressure and temperature conditions.
