Brass Hand Valve for HVAC Refrigeration – Manual shut-off valve, forged brass construction, red ergonomic handle. ODF solder and SAE flare connections. Max working pressure 4.5MPa. Temperature range -25°C to +100°C. Compatible with R22, R134A, R410A, R502, R407C.
Our Brass Hand Valve is a manual shut-off valve designed for one-way flow control in refrigeration, air conditioning, and cold storage systems. It regulates the flow of refrigerant, oil, and air on liquid, suction, and hot gas lines. The forged brass body with modified nylon valve core ensures reliable sealing, wear resistance, and high-temperature performance.
The ergonomic red handle allows quick open/close operation — only one and a half turns to fully open or close. The sand-blasted surface provides a comfortable grip without sharp edges.
