Overview

MDF‑B03‑32H002 is heavy‑duty piston‑type pilot operated normally closed solenoid valve from MDF‑B series, designed for large-capacity HVAC and commercial refrigeration systems. It adopts 1‑5/8 inch ODF solder connection with Kv value up to 15 m³/h, delivering superior large-flow refrigerant transmission capacity compared with smaller models. This model supports flexible procurement: customers can select complete valve assembly (valve body plus coil), or buy valve body and coil separately according to project spare part planning. Optimized heavy-duty piston structure improves flow passage design and reduces internal flow resistance. It can operate reliably under medium temperature ranging from -40℃ to +140℃, coping with pressure fluctuations in large refrigeration racks. Matched MQ series coil has IP67 double sealing protection, stable performance under high humidity and condensation environment. The modular structure allows quick coil replacement without removing the whole valve from pipeline, lowering system downtime for large HVAC&R projects.

Key Features

Multiple procurement choices: complete valve+coil assembly or separate valve body / coil purchase for flexible project stocking
1‑5/8 inch large ODF solder port and Kv=15 m³/h, offers outstanding high refrigerant flow capacity for large refrigeration racks
Optimized piston flow channel design, reduces internal flow resistance and cuts pressure loss during refrigerant circulation
Wide medium temperature range -40℃ ~ +140℃, adapts to deep freezing and high-temperature heat pump working conditions
IP67 double-sealed matching coil, low power consumption, stable operation under moist and condensate environment
Modular assembly design, coil can be replaced directly without removing valve body from piping, shorten maintenance time
Wide refrigerant compatibility, supports HCFC, HFC and new low-GWP HFO refrigerants for modern HVAC&R systems
Complies with PED, LVD, TUV and CQC certification, meets global export standards for large commercial refrigeration equipment
