420 bar ND12.7 Valves

DESCRIPTION :

MRTech 420 bar ND12.7 valves are the latest issue of the valves that are used in most of HP gas cylinders filling units in the world.

The 420 bar ND12.7 valves have been strictly designed to work up to 420 bar pressure, and they have been tested and approved by AIR LIQUIDE CTE (Expertise Technological center).
These are the unique valves of the market specifically designed for Oxygen filling at 300 bar pressure up to 420 bar.

MRTech HP ND12.7 valves take the benefits of technological improvments that have been patented : oxygen, nitrogen, argon, CO2, neutral gases, acetylen, hydrogen, hélium, corrosive gases on request.

• Double ring tightness to increase safety
• Decompression chamber to soften pressure shots
• Inclined inlet and outlet to improve gas circulation Inside the valve
• Balanced valves :no specific effort is required to handle the valves
• Incrémental valve aperture to prevent flexible hoses and piping from line shock
• High quality standards of materials, parts and manufacturing which is the guarantee of safety and reliability
• Easy maintenance
• Valves can be coupled in block mounted valves
• Easy changeover frommanual valve to pneumatic valve

Gas compatibility : oxygen, nitrogen, argon, CO2, neutral gases, acetylen, hydrogen, hélium, corrosive gases on request.
