Overview

MDF‑A03‑10H002 is a mini‑size diaphragm pilot‑operated normally‑closed solenoid valve, specially developed for household HVAC and light‑duty small refrigeration equipment. Featuring 1/2‑inch ODF solder connection and Kv value 1.9 m³/h, this compact‑sized valve occupies minimal installation space, perfectly matching small‑tonnage heat pump and refrigeration unit layout constraints. Optimized diaphragm structure realizes stable opening under low differential pressure, delivers excellent tight‑shut‑off performance during long‑time system standby. The lightweight forged brass body has good vibration resistance, adapts to frequent start‑stop cycles of household cooling appliances. Compatible with HCFC, HFC and low‑GWP new refrigerants, it provides reliable on‑off protection for liquid refrigerant circuits of small‑capacity HVAC&R devices。

Key Features

Miniature compact overall structure, greatly saves internal cabinet mounting space for small‑tonnage cooling units
Optimized small‑size reinforced diaphragm, stable actuation under low working differential pressure for household equipment
Kv 1.9 m³/h flow characteristic, precisely satisfies refrigerant circulation demand of household and light‑duty refrigeration systems
Excellent static sealing performance, low internal leakage even under long‑term high‑pressure standby status
Light‑weight forged brass valve body, anti‑vibration property, adapts to frequent start‑stop working cycles of household appliances
Good tolerance for minor system impurities, reduces stuck‑valve risk for small‑bore flow channel
Broad refrigerant compatibility, supports traditional HCFC/HFC and modern low‑GWP refrigerants for HVAC&R
PED and LVD compliant, satisfies global export certification requirements for household and light‑commercial cooling devices
