Overview

SHF‑35B‑67‑06 is a variable‑frequency‑optimized four‑way reversing valve developed for 35‑ton grade inverter‑driven heat‑pump HVAC systems. It is specially tuned to cope with frequent pressure and load fluctuations inherent to variable‑speed compressors. The upgraded internal driving structure enables reliable reversing within a wide differential pressure window, performing stable mode transition even when system pressure difference is low during low‑frequency running. The reinforced spool‑guide assembly mitigates wear caused by continuous dynamic load changes during variable‑frequency operation. It maintains excellent sealing performance under fluctuating operating conditions, suppresses internal refrigerant cross‑leakage during frequency rise‑and‑fall cycles. This valve fully adapts to dynamic operating logic of modern inverter heat‑pump units, delivers consistent cycle switching performance for commercial variable‑speed air‑source heat pumps and energy‑saving HVAC refrigeration equipment, and supports multiple types of low‑GWP environmentally friendly refrigerants.

Key Features

Optimized mechanical structure for inverter heat‑pump variable‑load fluctuating operating conditions
Wide working differential pressure range, reliable reversing even under low‑pressure‑difference low‑frequency operation
Reinforced spool guide assembly, reduces abrasion under continuous dynamic load variation
Stable sealing property during compressor frequency rise‑fall cycles, minimizes refrigerant cross‑leakage
Good compatibility with multiple low‑GWP environmental refrigerants including R32, R290 besides traditional HFC refrigerants
Anti‑vibration internal construction, resists vibration excitation transmitted from variable‑speed compressor
ODF copper pipe port dimension, matches mainstream 35‑ton inverter heat‑pump pipeline layout
Verified long service‑life performance under repeated variable‑frequency cyclic switching tests
