Overview

MDF‑B03‑25H004 is heavy‑duty piston‑type pilot‑operated normally‑closed solenoid valve belonging to MDF‑B series, engineered for large‑capacity industrial HVAC and severe‑working‑condition refrigeration systems. Compared with MDF‑A03 series, this B‑series valve adopts reinforced piston pilot mechanism and obtains broader medium temperature adaptability from ‑40℃ up to +140℃, together with 10.0 m³/h high Kv value for massive refrigerant circulation. It is equipped with 1‑3/8‑inch ODF solder port for large‑size piping layout. The robust piston structure delivers outstanding resistance to pressure surge and thermal shock, performing stably under frequent compressor start‑stop and high‑temperature exhaust pipeline conditions. It supports multiple traditional and low‑GWP refrigerants, maintains reliable tight shut‑off under high static pressure, and adopts detachable service‑friendly structure for on‑site maintenance for large‑scale refrigeration installations。

Key Features

Reinforced heavy‑duty piston pilot construction, excellent anti‑pressure‑surge performance for industrial cyclic pressure impact
Extra high Kv value 10.0 m³/h, meets large‑volume refrigerant circulation requirement of industrial‑grade refrigeration systems
Ultra‑wide medium temperature range ‑40℃ ~ +140℃, adapts to high‑temperature discharge line and deep‑freeze low‑temperature pipeline
1‑3/8 inch ODF large‑bore solder connection, matches large‑diameter piping for heavy‑duty industrial cooling equipment
Detachable valve body structure, supports field disassembly and maintenance, reduces overall equipment service cost
Stable sealing performance under long‑term high static pressure, effectively lowers internal leakage for long‑time standby status
Wide refrigerant compatibility, supports HCFC, HFC and modern low‑GWP HFO refrigerants for modern HVAC&R industry
Complies with PED and LVD directives, meets global certification requirements for large industrial refrigeration devices
