A diaphragm valve for a high speed reciprocating pump includes a valve seat defining at least one channel for fluid to flow through. The channel includes a support disposed therein. A diaphragm extends over the channel and is biased towards a closed position by a raised rim on the valve seat. An indented valve face under the diaphragm is shaped such that the fluid will exert a forward force on an area of the diaphragm which is greater than the cross-sectional area of the channel. The support in the channel supports the diaphragm during the reverse cycle of fluid flow. The valve therefore is durable and consumes a minimal amount of energy.

[ The embodiments of the invention in which an exclusive property or privilege is claimed are as follows:] [1.] A diaphragm valve for a high speed reciprocating pump, said valve adapted to allow a fluid to flow through said valve in only a downstream direction, said valve comprising:a valve seat having an upstream and a downstream side, said valve seat having a valve face indented into said valve seat and surrounded by a rim, at least a portion of said valve face extending into said valve seat at an angle such that said valve face is indented into said valve seat to maximum extent adjacent said rim;at least one channel defined by said valve seat, said at least one channel intersecting said valve face; anda diaphragm disposed in said valve seat having an upstream surface facing said valve face, said diaphragm being formed in a generally planar shape, said diaphragm movable between an open and a closed position, said diaphragm fluidly sealed against said rim when said diaphragm is in the closed position, said rim disposed in said valve seat such that said diaphragm is bowed from said generally planar shape and biased towards the closed position.
