200bar Medical Oxygen Valve Air Nitrogen Gas Bottles Valve
200bar medical oxygen valve air nitrogen cylinder valve
200bar common valve models: QF-5, QF-42E,QF-28,QF-40B, etc
Product Information:
1. In order to ensure the safety of use, it is stipulated that the outlet spiral direction of gas cylinder valve should use left screw thread for combustible gas and right screw thread for non-combustible gas.
2. Cylinder valves of different media are generally used in different structures. Their common characteristics are mostly manual, simple structure, small size, high strength,
3, 200bar cylinder valve: working pressure: 200bar; Test pressure: 300bar, working temperature in -40~60℃, material can adapt to the physical and chemical characteristics of the medium and commonly used copper, some with safety discharge device.
4, cylinder valve according to the structure is divided into axial type, flap type, needle form, rubber connection type and diaphragm type. Their range of action is the pressure range for compressed gas and the temperature range for liquefied gas.
5,In the shape and identification before the valve body strength test and opening torque, opening range, vibration resistance, resistance to humidity, high temperature (or low temperature) and vacuum test.
6、Alias: Oxygen gas Valves, Air Gas Valves, Air Gas Valves, Medical Oxygen valves

200bar oxygen and strong oxidation gas cylinder valve sealing materials, liquefied petroleum cylinder valve handwheel must be used flame retardant materials. The main performance test items before delivery are air tightness test, safety device action test;
Metallic and non-metallic materials in contact with gases in the working environment shall be compatible with the medium contained in the cylinder, as specified in ISO 11114-1 and ISO 11114-2.
The mechanical properties of metal parts after forging, pressing and machining should meet the design strength requirements of the valve.
When brass is used for dissolving acetylene cylinder valves, the copper content should not exceed 65.0%.
Liquid ammonia cylinder valves should not be made of copper alloy.
Liquid chlorine bottle valves should be made of materials resistant to hydrochloric acid corrosion.
The valve body material
The valve body material should not be changed from plastic to brittle materials (such as copper alloy, austenitic stainless steel, aluminum alloy and nickel alloy, etc.), and should meet the design strength requirements of the valve body, the performance of the material should meet the corresponding national standards.
Cylinder valve refers to the valve installed on the cylinder to control gas on and off and flow rate. Also known as "bottle valve".
