Abstract: An inlet section for use in a hydraulic distributor including a valve body and a slider with a first area and a second area. The inlet section further including said slider being longitudinally slidable within the valve body between a first position in which it prevents passage of fluid from a high pressure line to a low pressure line, and a second position in which it enables passage of fluid. The inlet section further including a main spring active on the second area of the slider in a direction consistent with action of the second pressure and a control device of the slider. The control device of the slider includes a mechanical actuator member selectively active on the slider in a direction consistent with the action of the first pressure on the first area of the slider so as to force the slider in the second position.

Abstract: A method of preventing drippage in a liquid dispensing system includes generating at least a first proxy signal representing at least a first indirect measure of a position of a first automatic control valve (ACV), wherein the first ACV has positions ranging from fully closed to fully open. The method further includes recognizing, based on at least the first proxy signal, whether a failure state exists in which the first ACV has failed to close. The method further includes causing a second ACV to close when the failure state exists, wherein the second ACV is fluidically connected to the first ACV, and the second ACV has positions ranging from fully closed to fully open.

Abstract: A method of preventing drippage in a fluid dispensing system. The fluid dispensing system includes a first automatic control valve (ACV), an input of the first ACV connected to fluid-source of fluid, the first ACV having positions ranging from fully closed to fully open, and a second ACV, an input of the second ACV being connected to an output of the first ACV, and an output of the second ACV being connected to a nozzle, the second ACV having positions ranging from fully closed to fully open. The method includes generating a first proxy signal representing at least a first indirect measure of a position of the first ACV. The method includes recognizing, based on at least the first proxy signal that a failure state exists in which the first ACV has failed to close. The method includes causing the second ACV to close when the failure state exists.

Abstract: A valve apparatus comprises a valve body defining a flow path therethrough, a valve member mounted within the valve body, and an actuator assembly mounted internally within the valve body. The actuator assembly comprises a piston bore and piston member defining a piston chamber therebetween, wherein at least one of the piston bore and piston member is engaged or associated with the valve member such that the valve member is moveable in accordance with fluid pressure within the piston chamber to selectively occlude the flow path.

Abstract: A particle blast apparatus includes a metering portion, a comminutor and a feeding portion. The metering portion and comminutor may each be configured to provide uniformity in the discharge of particles. The metering portion controls the particle feed rate, and may include a rotor, which may have V or chevron shaped pockets. The comminutor includes at least one roller which may be moved between and including a position at which the gap of the comminutor is at maximum and a position at which the gap is at minimum. The metering portion may particles direction into the feeding portion without a comminutor being present. The comminutor may receive particles directly from a source of blast media without a metering portion being present.

Abstract: A modular liquid distribution system in which each module has a module body, a spray nozzle, and a piston for controlling the dispensing of liquid from the nozzle. Each module has a pneumatically operated system for moving the piston to an open position while facilitating quicker return movement to a closed position, enabling the dispensing of precisely controlled small droplet sized quantities of highly viscous liquids.

Abstract: A metering valve for introducing media into a pressurized fluid includes media passaging having a media inlet for receiving media and a media outlet for dispensing media toward the pressurized fluid. The media passaging defines a flow path extending from the media inlet to the media outlet and is configured to permit flow of media along the flow path. A plunger, including a plunger head, is movable between a closed position in which the plunger head forms a seal to prevent flow of media through the media passaging and an open position in which the plunger head permits flow of media through the media passaging. The seal formed by the plunger head includes a first sealing interface and a second sealing interface downstream along the flow path of the first sealing interface.
