Tilting Disc Check Valve (Long Type)
Check valve are generally used in drip irrigation emitters and irrigation sprinklers. Composition disc valves are ideal for applications involving gritty liquids. A clapper valve is a type of check valve which is used in fire fighting. Poppet check valves find use in "macro" flow applications. Arterial check valves are used in applications requiring centrifugal pumps to prevent retrograde flow along the arterial line.
