Valve Assembly ( OEM-National)
CSS offers high performance valves and seats are made of forged alloy steel with deep carburized wear surface. The valves and seats we offer have two major categories, full open valves and seats, 3 web / 4 web valves and seats. Full open valves and seats have many different designs which include uniformly forged FKN and Roughneck Styles.
The full open design of this bonded valve provides maximum fluid flow, and has a longer operation life due to its increased structural strength. This is the result of using a forged solid body instead of a two-piece design. This is done to provide durability at high pressures. The large metal- bearing area on the valve seat surface promotes a longer service life.
Our high quality valve assemblies are fully exchangeable with OEM parts. Continental Supply Services can supply high performance valve assemblies compatible with following models of National mud pumps.
