Product Description

Feature

1. Anti-combustion and fire resistance: The main components are made of copper alloy, which is a non-combustible material. Even if it collides with solid particles in high-speed airflow, it will not produce sparks. Therefore, this valve has the best fire and fire resistance.

2. Safe and reliable: This valve is equipped with dustproof, waterproof and oil-proof devices. All valves in contact with oxygen undergo strict degreasing and oil-free measures before assembly. The filler material is PTFE. It ensures safety and reliability when used.
