Overview

MDF‑B03‑40H002 is a top-tier ultra-large flow piston pilot-operated normally closed solenoid valve in the MDF-B heavy-duty series, specially optimized for high-load, large-tonnage industrial HVAC systems and super-capacity commercial refrigeration equipment. Equipped with 1-5/8 inch large-diameter ODF solder interface and an industry-leading 25.0 m³/h Kv value, this valve features a fully upgraded widened flow channel structure, which fundamentally reduces fluid resistance and pressure loss during refrigerant circulation, meeting the ultra-large volume circulation demand of central HVAC systems and industrial freezing units. Adopting an enhanced integral piston drive mechanism, it delivers exceptional pressure resistance and impact resistance, stably coping with extreme working conditions such as frequent pressure fluctuations, high static pressure standby, and high-temperature exhaust pipeline operation in large HVAC&R systems. It supports flexible diversified procurement methods, available as complete valve body and coil assembly, or separate purchase of valve body only and coil only, adapting to different project installation, after-sales replacement and spare parts stocking needs. With an ultra-wide medium temperature range of -40℃ to +140℃ and full compatibility with traditional HCFC, HFC and new low-GWP environmentally friendly refrigerants, it maintains precise and reliable tight shut-off performance in deep freeze, normal temperature cooling and high-temperature heat pump HVAC scenarios. The modular detachable structure and IP67 fully sealed supporting coil greatly improve the adaptability of harsh unit environments, realizing long-cycle stable operation for industrial and large commercial HVAC refrigeration systems.
