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 (G)-13H-45 stainless steel 4-way reversing valve is a specialized model in the small-size series, designed for medium-to-small flow, high-pressure applications. Its core feature is the 13H nominal diameter, providing high-pressure compatibility. Combined with 304 stainless steel corrosion resistance, it is suitable for small high-pressure hydraulic equipment, precision high-pressure fluid systems, and similar applications.

Key Specifications:

  • Nominal Diameter: 13H (suitable for DN13 pipelines)

  • Operating Pressure Range: 1.0–5.0 MPa (high-pressure capability)

  • Operating Temperature: -15℃ to 120℃

  • Recommended Flow Rate: 4–10 m³/h

Compared with the 7H/4H models in the same series, this model increases the pressure upper limit by 2.0–3.0 MPa. The valve body uses a thickened stainless steel casting process, achieving a pressure resistance of 8.0 MPa. The internal sealing structure uses high-pressure-specific metal seals.

Technical Advantages & Innovations:

  • High-pressure balanced valve plate design reduces switching resistance under high pressure.

  • Switching response time ≤ 0.5 s; 100% switching success rate under 5.0 MPa.

  • High-pressure erosion-resistant internal flow channels, with a service life exceeding 60,000 cycles.

  • Valve body includes a high-pressure safety relief interface, which can be connected to a relief valve to enhance system safety.

Target Applications:

  • Small High-Pressure Hydraulic Equipment: Hydraulic oil direction control for small hydraulic presses and high-pressure jacks, ensuring precise pressure control.

  • Precision High-Pressure Fluid Test Devices: Directional control of experimental high-pressure fluids, compatible with laboratory pressure requirements.

  • Small High-Pressure Cleaning Equipment: Flow switching for handheld high-pressure washers, ensuring cleaning performance.

Installation & Compatibility Notes:

  • Use high-pressure-specific seals and piping during installation to ensure system pressure integrity.

  • The valve body must be firmly fixed to prevent interface loosening due to high-pressure switching vibrations.

  • During commissioning, strictly control pressure ramp-up speed and check the relief function for proper operation.
