Abstract

A control valve, primarily intended for use in the spraying of pressurised liquid, has a body (13) having an inlet (11), an outlet (12), and a liquid flow path through the body from the inlet to the outlet, there being in the flow path a spring disc (31) which is responsive to inlet liquid pressure to cause it to snap over between a closed position, which it engages a valve seat (19) to prevent flow through the valve, and an open position, where it is disengaged from the valve seat, to permit flow, the disc moving to its open position at a liquid pressure equal to or higher than the liquid pressure at which it moves to its closed position. The valve can include a restrictor (29) which co-operates with a further valve seat (20) to reduce the pressure of liquid flowing from the valve seat (19) which the spring disc engages in its closed position. <IMAGE>
