There is a sufficient diametrical clearance between the poppet and the liner which allows for flow control at pressures which are less than the initial opening pressure.

Abstract: A method for arranging a valve element in an additional control valve device includes provides that, after a first position has been set, a valve plate is pushed onto the stem until the valve plate contacts the stop of a trapping magnet. The valve plate is then connected to the stem. This ensures that the fabrication tolerances are completely compensated by virtue of the first valve spring and the guiding of the valve element. After the second counter bearing has been secured in the guide, the holding of the first counter bearing in the previously determined first position is cancelled, which is then generally carried out by removing the tappet from the guide. After this has been done, the valve element automatically assumes a central position between the gantry magnet and the trapping magnet in the currentless state of the additional control valve device owing to the spring forces which then act.

Abstract: A water saving device, implemented as a pair of spring loaded, normally-open shutoff valves inserted into the hot and cold water supply lines of a faucet, which are connected via a cable mechanism to a foot actuator. Actuating the mechanism causes the shutoff valves to close, interrupting any flow of water in the supply lines. Releasing the mechanism allows flow to resume. The shutoff valves are installed in series upstream of the normal hand-operated faucet valves. The user starts the water flow and adjusts the temperature of the water in the normal manner using the hand-operated faucet valves. When the user wishes to temporarily stop the water flow he or she steps on the foot pedal, thereby causing the shutoff valves to close. When the pedal is released the shutoff valves open and the water flow resumes at the same flow rate and temperature previously set by the user.
