ABSTRACT:
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.
