Product Features:
1. Fire prevention and fire resistance: the main components are made of copper alloy, which is a non-combustible material. Even if the collision with solid particles in the high-speed air flow will not produce sparks. Therefore, the valve has a good fire resistance performance.
2, safe and reliable: the valve with dust-proof, waterproof, anti-oil device, all the oxygen contact valve parts before assembly are strictly degrease and oil ban measures, packing material is PTFE, can ensure the use of safe and reliable.
