一.Product Introduction
The special globe valves for JY41W and JY41Y oxygen are cast from silicon brass or stainless steel with excellent materials, which have the advantages of high mechanical strength, wear resistance and good safety.Used on oxygen pipelines, it has the best explosion-proof and flame-retardant properties, eliminating unsafe factors on oxygen pipelines.
二.Product Features
- Anti-combustion and fire resistance: The material of the main components is copper alloy, which is a non-combustible material. Even if it collides with solid particles in the high-speed air flow, it will not produce sparks.Therefore, this valve has the best flame-proof and fire-proof performance
- Safe and reliable: This valve is equipped with dust-proof, waterproof, and oil-proof devices. All valve parts in contact with oxygen are strictly degreased and oil-proof measures before assembly. The packing material is polytetrafluoroethylene, which can ensure safety and reliability when used.
