Product Information:
1. Cylinder valve refers to the valve installed on the cylinder to control the on-off and flow of gas. Also known as "bottle valve".
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, 150bar cylinder valve: working pressure: 150bar; Test pressure: 250bar, working temperature in -40~60ºC, the material can adapt to the physical and chemical characteristics of the medium requirements and commonly used copper, some with safety release device, such as tensile or shear type bursting disc and fusible alloy made of safety plug.
4. Cylinder valve is divided into valve type, shaft type, needle type, rubber connection type and diaphragm type according to structure. Their range of action is the pressure range for compressed gas and the temperature range for liquefied gas.

200bar medical oxygen valve air nitrogen cylinder valve
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 -40~60ºC, 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, 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;
6, 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.
