OxyGen Valve

Oxygen valve is a specialized valve designed for oxygen systems, with the core function of safe delivery and control. It adopts a strict oil free design (degreasing treatment of all components) to prevent oil from igniting when exposed to high-pressure oxygen. Structurally, safety is ensured through metal hard sealing (such as nickel based alloys) and anti-static devices. The flow channel is mirror polished (Ra ≤ 0.4 μ m) and double sealed (leakage rate ≤ 10 ⁻⁶ level) to ensure oxygen purity. Divided into three categories based on function: 1) Quick disconnect type (response ≤ 1 second), used for emergency shutdown; 2) Precision adjustable type (flow error ± 3%), suitable for medical oxygen supply; 3) High pressure type (pressure bearing above 15MPa), used in industrial scenarios. It must comply with international safety standards such as ISO 15001 and be widely used in medical, air separation equipment, and aerospace fields.

High purity medium guarantee

01
Ultra smooth channel
channel mirror polishing (Ra ≤ 0.4 μ m), reducing impurity adhesion and oxygen pollution;
02
Zero leakage seal
Double sealed structure (corrugated tube+graphite packing), leakage rate ≤ 10 ⁻⁶ level;The sleeve type regulating valve adopts a V-shaped sphere or hard seal to achieve precise flow control.

Intrinsic safety design

01
Strictly prohibit oil degreasing
all components undergo degreasing treatment (in accordance with ISO 15001) to eliminate the risk of oil self ignition and explosion when exposed to high-pressure oxygen;
02
Anti friction spark structure:
The double eccentric butterfly valve adopts a combination of eccentric bearings and butterfly plates to reduce friction between the valve disc and the valve seat;The globe valve adopts a pure lifting motion of the valve stem to avoid rotational friction;
03
Anti static grounding
The valve body is integrated with a static conductive device to eliminate the accumulation of static electricity;Flame retardant materials: Priority should be given to using flame-retardant materials such as silicon brass and stainless steel to prevent high-temperature explosion.
