The DruvaPUR 20 m³ Range CV300 SSG high-purity non-return valve is ideal for supply systems handling inert, flammable, oxidising, and corrosive gases up to a maximum purity of 6.0.
Ensure safety and efficiency in pipelines by preventing undesired backflow of gases with the Druva high-purity non-return valve. Built to withstand working pressures of up to 300 bar, it is suited for high-pressure applications where gas flow direction must be strictly controlled. Its robust stainless steel body offers exceptional resistance to wear and corrosion. This high-purity check valve is mounted in the high-pressure areas of manifolds, where it protects compressed gas cylinders from reverse flow in the event of an operational error. Its specialised seat seal and the use of carefully selected gas-wetted materials make it compatible with oxygen up to 300 bar. The CV300 SSG eliminates the need for the oxygen ignition test typically required for non-metallic seat-sealed check valves during development, thanks to its carefully selected materials.
