Overview

MDF‑B03‑40H004 is a heavy-duty large-flow piston pilot-operated normally closed solenoid valve within MDF-B series, engineered for large tonnage industrial HVAC and continuous running commercial refrigeration racks. It adopts optimized internal sealing structure together with 1-5/8 inch ODF solder connection and 25.0 m³/h Kv rating. Compared with similar models, it upgrades internal sealing pairs for better pressure retention, effectively reducing static leakage under long standby pressure conditions in HVAC&R systems. The reinforced piston assembly maintains stable switching action under recurring pressure surges during unit startup and shutdown. Customers may order full assembly of valve body plus coil, or buy valve body and coil individually, convenient for on-site maintenance and spare parts inventory management. The medium temperature covers -40℃ to +140℃ and works with HCFC, HFC and low-GWP eco-friendly refrigerants. It is built to sustain continuous 24/7 operation for central HVAC, industrial freezer and large cold storage, the IP67 sealed coil provides reliable protection against moisture and condensation inside refrigeration units.
