  • Pneumatically operated inlet water valve
    Patent number: 6786782
    Abstract: A pneumatically operated valve is provided for use in conjunction with a seacock, or in place of a seacock, so that flow of water through the hull of a marine vessel can be blocked more easily than by manually manipulating the lever of a standard seacock. A controller is provided at a convenient location so that the operator of a marine vessel can pressurize a pressure line which closes the pneumatically operated valve and blocks water flow through the seacock. A spring return can be used so that the pneumatically operated valve is urged toward an open position when pressure is not provided by the operator of the marine vessel. In certain embodiments, sensors can be provided so that an ignition system can not be actuated when the pneumatically operated valve of the present invention is in a closed position.
