GAMART offers check valves, anti-pollution check valves and venting and aeration valves.
Check valves are used in water supply and sewage systems to protect against back flow of liquids. Depending on the application, they are available as ball-elbow, ball-flange, ball-threaded, mushroom, flap, flange with diameters from DN 50 to DN 600, working pressure max. 1.0 MPa, 1.6 MPa, 2.5 MPa and the operating temperature of max 150 degrees C.
Anti-contamination check valves are used in water supply systems to protect against secondary contamination of the network caused by backflow. They are manufactured as threaded in the range of DN15 to DN50, and as flanged in the diameter range of DN50 to DN200, with a maximum working pressure of 1.0 MPa or 1.6 MPa and an operating temperature of up to 120 degrees C.
On the other hand, venting and aerating valves are used in the installation for the transmission of water and sewage for venting and aerating pipelines with diameters from DN 50 to DN 200 at an operating pressure of max. 1.0 MPa or 1.6 MPa and the operating temperature of max 70 degrees C.
