A gate valve (http://www.valvesupplier.net/index.htm) is a valve that opens by lifting a round or rectangular gate/wedge out of the path of the fluid. Gate valve (http://www.valvesupplier.net/index.htm) is sometimes used for regulating flow, but many are not suited for that purpose, having been designed to be fully opened or closed.
