Overview

MDF‑B03‑25H003 refrigeration solenoid valve is piston‑type pilot operated normally closed solenoid valve of MDF‑B heavy‑duty series, widely used in HVAC and industrial refrigeration systems, with 1‑1/8 inch ODF solder connection and Kv value of 10.3 m³/h. This model supports flexible procurement options: customers can order complete assembly (valve body + coil) as shown in our product picture, or purchase valve body and coil separately according to project demands. Equipped with reinforced piston structure, it works stably within ultra-wide medium temperature range from -40℃ to +140℃, suitable for low-temperature freezing and high-temperature exhaust pipeline conditions. The matched MQ series coil adopts double sealing design reaching IP67 protection grade, featuring low power consumption and strong moisture resistance. For heavy‑duty HVAC and industrial refrigeration and large heat pump systems, it delivers reliable tight shut‑off under high static pressure, and the detachable construction simplifies on‑site inspection and component replacement without replacing the whole valve.

Key Features

Flexible procurement mode: available as complete valve+coil assembly or separate valve body / separate coil for customized project procurement
1‑1/8 inch ODF solder port, 10.3 m³/h high Kv value, delivers stable large refrigerant circulation for industrial refrigeration racks
