Brass check valves are the simple devices for preventing reverse flow of fluid when the direction of its movement reversed. Check valves of our production have a classic design of the spring valve (body consists of two threaded parts, connected by a thread, fixed anaerobic adhesive) gate unit consists of brass stem with washer and seal (EDPM), and is supported with conical return spring of stainless steel (ANSI 302). All the valves are tested for pressure, which guarantees high quality and reliable service for a long time. Check valves are manufactured in three variants - the "Standard", the "Premium" and the "EURO" and differ from each other by wall thickness, weight, and higher working pressure.
