An automatic angle stop assembly for a urinal or toilet may include an angle stop adjustment device and an angle stop. The automatic angle stop assembly may automatically control flow through the angle stop to a flush valve. The automatic angle stop assembly may include a motor and an adjustment screw. A method for closing the angle stop may include sensing a flow condition, automatically rotating a motor based on the flow condition, and closing the angle stop.

The present disclosure provides convenience of use by automatically displaying a display of OPEN or CLOSE displaying an open or closed state of a valve according to the manipulation of a handle portion.

Provided is an electric valve, including a valve seat and a valve needle, and the valve needle is mounted in the valve seat; a valve core, which is mounted at an end of the valve seat, and the valve core forms a valve opening; a driving assembly, which drives the valve needle to axially move so as to open and close the valve opening; the valve core is made of a non-metal material, an inner wall or an end face of the valve core forms a sealing face, and the sealing face and an outer wall face of the valve needle form a soft sealing structure. Through the soft sealing structure composed of the valve core and the valve needle, the technical problem of poor sealing performance of the electric valve can be solved.

A cooling tower by using a valve with an adjustable disk. Thus, a cooling tower flow control inlet valve for modulating the flow of return water entering a cooling tower by using a valve with an adjustable disk. The cooling tower flow control inlet valve includes a valve body assembly, a valve stem assembly, a backplate assembly, and a valve and permits regulated flow through the spatial rotational placement along the valve stem of the adjustable disk.

A valve stem for use with a choke valve is disclosed. The valve stem has a valve stem body with a valve stem head removably connected to the valve stem body. A locking device prevents the unwanted loosening or removal of the valve stem head from the. valve stem body. The locking, device may be a fastener with a thread having a different direction than the thread that attaches the valve stem head to the valve stem body.

A system including a valve, including a valve body having an interior volume and a bore along a first axis, a stem extending along a second axis, and a flow control element coupled to the stem, wherein the stem is configured to selectively move the flow control element through the interior volume between a closed position and an open position relative to the bore, and a valve insert system configured reduce a size of the interior volume and to guide a lubricant to reduce wear on the flow control element.
