Z41H-16C gate valve is a valve that opens by lifting a round or rectangular gate/wedge out of the path of the fluid. The distinct feature of a gate valve is the sealing surfaces between the gate and seats are planar, so gate valves are often used when a straight-line flow of fluid and minimum restriction is desired. Z41H-16C gate valvefaces can form a wedge shape or they can be parallel. On opening the Z41H-16C gate valve, the flow path is enlarged in a highly nonlinear manner with respect to percent of opening.
