Overview

MDF‑A03‑20H004 is a high‑flow pilot‑operated solenoid valve designed for medium‑to‑large capacity HVAC and commercial refrigeration systems. Optimized for large refrigerant flow demands, this ODF solder‑type cut‑off component delivers stable opening performance under high differential pressure conditions. Compatible with multiple mainstream HFC, HCFC and low‑GWP refrigerants, it maintains reliable sealing performance within wide medium and ambient temperature ranges. Robust brass valve body structure resists system vibration and cyclic pressure fluctuation, ensuring long‑term stable on‑off control for liquid, suction and discharge refrigerant lines in heat pump, chiller and commercial refrigeration equipment.
