A combined dirt collector and cutout cock (CDC & COC) device for a rail car control to prevent unintentional re-pressurization of the control valve and rail car braking system. The device has an inlet configured for interconnection to an air supply, an outlet configured for interconnection to a control valve of a rail car, a valve moveable between a first position where an inlet is connected to an outlet and a second position where the inlet is isolated from the outlet, and a control valve vent positioned downstream of the valve and configured to open in response to the valve being moved into the second position. The valve may include a ball having a first passageway for selectively connecting and disconnecting the inlet from the outlet and a second passageway formed therethrough that is positioned to interconnect the outlet with the vent when the valve is in the second position.

The present disclosure relates to valve lockout systems, including valve lockout systems for use with an actuator and butterfly valves. The lockout system allows controlled access to operation of the valve, either to prevent intentional or unintentional operation of the valve. Thus, the lockout system prevents the unauthorized opening or closing of the valve. The lockout system includes a lockout plate in which a lockout bar is positioned. The lockout bar includes a surface containing a recess. Depending upon the location of the recess the valve shaft can be opened or closed.

Provided are a valve device free of changes in the position of the valve member caused by external force and fluid pressure, and a lock device for the valve device. The lock device has a tubular member fitted to the rotating part of the valve device so that the member is movable along the axis of the rotating part in both directions, wherein the member has a protrusion on its inner circumferential face along its axis, and the protrusion engages with or disengages from recesses in an outer circumferential face of a holder of the rotating part formed along its axis when the member moves in either direction; or the member has recesses in its inner circumferential face formed along its axis, and the recesses engage with or disengage from a protrusion on the outer circumferential face of the holder along its axis when the member moves in either direction.

A faucet with two outlets includes a main body, an outlet pipe, a hot water inlet conduit, a cold water inlet conduit, a cold water conduit, a filtered water conduit and a switch member. The outlet pipe has an inner channel and an outer channel. Filtered water flows through the inner channel, running water flows through the outer channel. The switch member laterally formed a peripheral wall of the main body, and having a valve core being mounted inside the main body. The valve core has control filtered water or running water outlet from the outlet pipe. The faucet with two outlets respectively outputs filtered water and running water through two different waterways in the outlet pipe and ensures simple structure, convenient operation and multiple water output modes.

Improvements in a one-way valve cap to allow a homeowner to install the cap without requiring tools. This allows a homeowner to simply remove the existing cap and install the new cap to prevent removal from an unauthorized person. The one-way locking mechanism includes a ramp that prevents a person from unscrewing to cap without a tool. The opening allows a person to insert the tool through the outer housing and into the inner housing to unscrew the inner housing from the valve. A hex key or a custom key design can be used for removing the cap. A seal is inserted in the inner housing and seals the inner housing with the valve. The elastomeric seal prevents intrusion of contamination inside of the valve and also provides an additional seal to the valve to reduce a potential leak of gas from the line.

A leak detection and prevention system includes a gear motor linkage assembly. The gear motor linkage assembly includes a gear motor and a gear motor controller/driver module that controls operation of the gear motor. The gear motor linkage assembly also includes a push lever attached to a shaft of the gear motor, the push lever in a home position, wherein when a signal indicating that a leak has been detected is received the gear motor controller/driver module controls the gear motor to rotate the push lever so that the push level non-captively engages a handle of a valve and pushes the handle to a closed position, then the gear motor controller/driver module controls the gear motor to rotate the push lever to the home position.

A system includes an actuator housing having a plurality of adapter lugs extending radially inward toward an axis, each adapter lug of the plurality of adapter lugs secured to the housing via a respective connector. The system also includes a bonnet having a plurality of bonnet lugs extending radially outward away from the axis, each bonnet lug of the plurality of bonnet lugs being separated by a respective space, the space being sized to permit axial movement of an adapter lug of the plurality of adapter lugs toward a lower flange arranged axially lower than the plurality of bonnet lugs.

A gas fixture safety cover comprising: a plurality of walls, and a plurality of nozzle slots located in the walls, and plurality of handle slots located in the walls, the walls and slots configured to allow the gas fixture safety cover to slide over a gas fixture and abut a countertop if all of the gas valve handles are in an off position, and further configured to prevent the gas fixture safety cover from sliding over a gas fixture and abutting a counter top if any of the gas valve handles are in a turned on position.
