ABSTRACT:
A valve intended primarily for use on the end of a supply hose for directing and controlling a high velocity stream of an abrasive granular material against an object. The valve has a handle with a usual discharge nozzle mounted on one end thereof, with the granular material supply hose being connected to the other end of the handle. A lever is pivotally mounted on the handle and is movable between open and closed positions with respect to the nozzle. The lever has a hand-actuated inner end portion and a nozzle sealing outer end portion. A spring is mounted on the lever and biases the lever toward closed position. A resilient sealing member is mounted on the outer end of the lever and forms a seal completely external of the nozzle against the open discharge end of the nozzle when the lever is in closed position. Magnets may be mounted on the handle and inner end of the lever and are mutually engageable when the lever is in open position to assist an operator in overcoming the biasing effect of the spring.
