Abstract: An electromagnetic rising stem valve includes a stopper configured to block flow of fluid within a pipe. The stopper is connected to a shaft configured to be rotated via an electromagnetic force generated between magnets attached to the outside of the shaft and magnets surrounding an outside surface of a section of the valve. The rising stem valve is further able to include a second shaft which is directly rotated by the electromagnetic force, to open, closed, and one or more semi-open positions, and which is coupled to the shaft connected to the stopper via gearing. Advantageously, the one or more shafts and any gearing is entirely contained within a gear housing, with the electromagnetic force being generated by interaction with magnets outside the housing entirely, preventing unwanted leakage of fluid from the pipe into the environment.

Abstract: A device for locking a turning handle of a valve containing a handle for actuating a shut-off element of a valve, a latching ring that can be arranged in a rotationally conjoint manner on a valve housing support for an actuating device and an adapter that can be arranged on a drive journal of a shut-off element such that it can be fixed and released again, wherein the adapter and the handle are connected to one another in a releasable manner, wherein an axially displaceable and non-rotatable sliding ring is arranged on the handle, wherein the sliding ring can be displaced axially into a locking or open position and in the locking position the sliding ring locks the rotational movement of the handle and the handle cannot be removed from the valve on account of the position of the sliding ring in the locking position.

Abstract: A system that regulates a flow of a fluid through a valve is disclosed. The system includes a flow regulator and a spindle housing. The flow regulator includes a spindle that includes a channel that extends around a portion thereof and a flow adjuster that extends from the spindle. The spindle housing includes an aperture extending therethrough that receives the spindle, an inlet that receives the fluid and an outlet that expels the fluid. The flow regulator is rotatable relative to the spindle housing when the spindle is disposed in the aperture.

Abstract: A new and innovative high-pressure priming valve is provided for use in high-pressure fluid systems that require a high level of fluid purity. The priming valve includes at least three ports, some of which are angled. The priming valve also includes a needle that variably blocks and unblocks a pathway to one of the ports between normal operation and a priming operation, respectively. The priming valve includes a sealing insert positioned below a stack of washers that maintain the needle's alignment in response to high fluid pressures exerted on the needle. The sealing insert helps prevent fluid from contacting the stack of washers, which helps prevent biological growth within the valve. The angled ports help facilitate priming valve drainage to further help prevent biological growth. By helping prevent biological growth, the sealing insert helps prevent fluid contamination and enables the priming valve to be utilized for high-purity fluid applications.

Abstract: The invention relates to a valve handwheel, comprising a first handwheel part comprising a first position-indicating window, a second handwheel part comprising a second position-indicating window, and a geometrical centre axis extending through the first and second handwheel parts. The first handwheel part is rotatably connected to the second handwheel part. When a user turns the first handwheel part around said geometrical centre axis, the first position-indicating window rotates with the first handwheel part while the second position-indicating window remains stationary with the second handwheel part. The invention also relates to a valve arrangement comprising such a valve handwheel.
