Coarse water / gas filters and check valves 

Today it is difficult to imagine any technological process with a liquid or gaseous medium without the use of various options for check valves and filters for cleaning from mechanical particles and impurities. Brass water and gas mesh filters are widely used in water supply and gas supply systems, without them it is impossible to install water meters or gas automation elements, since mechanical particles, moving together with the working environment, can harm these devices, up to their breakage. Check valves made of brass and wafer type cast iron are automatic devices for controlling the flow direction. Spring-loaded brass valves are used in pumping equipment for the operation of closed and suction systems, cast iron wafer check valves are used in industry and pipeline systems to prevent the movement of the working medium in the opposite direction to the main one.
