		Disk check valves A tilting check valve. Construction: with spring, without spring. Mounting: vertical, horizontal. Applications: nitrogen, ammonia, fuel oil products (lube oil, benzene, kerosene, diesel oil, heavy oil (mazout)), butane, water, steam, acetone, hydrogen, oxygen, ethyl alcohol, methyl alcohol, not containing solid particles. Materials: gunmetal, cast iron, carbon, alloy, stainless steel. Connection type: interflanged, socket, flanged. Temperature up to +525 °С DN 8 - 1000 PN 10 - 100

		Check ball valve for much polluted mediums. The ball is built-in into the valve body. Materials: body – cast iron (for DN400 - steel), ball – aluminium with different coating (depend on material). Connection type: flanged, socket. Temperature up to +80 °С DN 15-400 PN 10

		Rubber check valves for polluted mediums Simple, reliable construction for protection against backflow. These valves do not require maintenance and repair, because there are no sliding, rotating and spring-mounted details, and also mounting seat. Materials: EPDM, viton, neopren, hypalon, buna-n. Connection type: flanged, with clamps. Temperature up to +200 °С DN 25-2400 PN 10
