Overview

MDF‑A03‑15H002 is a compact diaphragm‑type pilot‑operated solenoid valve optimized for residential and light‑commercial HVAC and refrigeration systems. Adopting 7/8‑inch ODF solder port and medium 2.3 m³/h Kv flow capacity, this valve features a flexible reinforced diaphragm structure that separates refrigerant medium from internal driving components, effectively avoiding medium contamination to actuation parts. It requires extremely low minimum operating differential pressure of only 0.005 MPa, delivering sensitive opening response under light‑load working conditions. The compact brass body occupies less installation space inside unit cabinets, compatible with multiple traditional and low‑GWP refrigerants. It maintains stable tight shut‑off performance under frequent cyclic on‑off, well‑suited for heat pump, small chiller and light‑duty refrigeration equipment liquid‑line protection。

Key Features

Reinforced diaphragm pilot construction, physical isolation between refrigerant and driving parts, reduce internal component contamination risk
Ultra‑low minimum operating differential pressure(0.005 MPa), sensitive opening response under light‑load low‑pressure‑difference conditions
Compact brass valve body, small overall footprint, perfectly adapts narrow cabinet installation space for light‑commercial units
Stable medium Kv value 2.3 m³/h, satisfies refrigerant circulation demand for residential and light‑cooling capacity equipment
Good anti‑impurity performance, diaphragm structure lowers stuck‑valve risk caused by fine debris inside refrigeration loop
Reliable sealing performance under repeated cyclic opening‑closing, keeps low internal leakage for long‑term standby state
Wide refrigerant compatibility, supports HCFC, HFC and new‑generation low‑GWP refrigerants for modern HVAC&R systems
Complies with PED and LVD directives, meets export certification requirements for light‑commercial refrigeration products
