A valve for a flush-mounted body of a sanitary fitting, at least having a valve housing with a longitudinal axis, a rotatable flow control element for adjusting a flow volume of a liquid flowing through the valve, and a valve knob for opening and closing the valve. The valve knob can be adjusted via the flow control element, rotationally and parallel to the longitudinal axis, by a control knob for the valve, and the control knob is fastened to the valve knob by a rotary coupling so that the control knob can be non-rotatably fastened relative to the valve housing.

What is disclosed is a pressure regulator having a mechanism to turn fluid flow through the pressure regulator on or off. The pressure regulator incorporates an actuator by which fluid flow to a pressure chamber that controls the linear movement of a flow tube is selectively actuated from one of a downstream supply and a pressurized fluid supply, such as an upstream supply. The actuator can be a manual, electromechanical, hydraulic or other form of actuator.

An operating structure of a pilot-operated solenoid valve is provided. The pilot-operated solenoid valve includes a valve body having a main valve orifice and a pilot valve orifice to open and close the main valve orifice. The pilot valve orifice communicates with an accommodating chamber of the valve body. The operating structure includes a knob, an adjustment rod, and a water stop nut. The knob is positioned and fitted to an opening of the accommodating chamber. The adjustment rod is hermetically fitted in the accommodating chamber. One end of the adjustment rod is threadedly connected to the knob, and the other end of the adjustment rod is connected to the water stop nut. The adjustment rod is driven to move axially by rotation of the knob for driving the water stop nut to control the opening and closing of the main valve orifice.

In an actuated valve assembly, the valve includes a valve body defining a fluid passageway, an annular valve seat disposed on the valve body surrounding the fluid passageway, and a valve closing member movable between a closed position sealing against the valve seat and a fully open position spaced apart from the valve seat to permit flow. The actuator includes an actuator housing and an actuating mechanism movable within the actuator housing, by operation of the actuator, between a closing position in which the actuating mechanism holds the valve closing member in the closed position, and an opening position in which the actuating mechanism permits movement of the valve closing member toward the fully open position, the opening position being defined by engagement of the actuating mechanism with a stop portion of the actuator. The actuator is threadably adjustable on the valve to adjust a position of the actuator stop portion with respect to the valve seat, such that the opening position of the actuating mechanism may be selected to limit the valve closing member to a partial flow position between the fully open position and the closed position.

A pivoting support assembly with a selective position locking capability may include a base, a first support arm movable with respect to the base, and a first movable joint movably mounting the first support arm to the base that includes a first component and a second component. A first position locking assembly may lock a selected position of the support arm with respect to the base, and may include a drum structure of one of the first and second components of the first movable joint and a shoe structure of another one of the first and second components of the first movable joint. The shoe structure may be movable to selectively move outwardly against the drum structure to resist rotation of the drum structure with respect to the shoe structure and thereby resist movement of the first support arm with respect to the base.

An inflation valve is provided and includes a valve defining main and command cavities and including first and second valve portions and a valve seat defining an outlet, a poppet disposed in the main cavity and including first and second rods to engage with the first valve portion and to extend through the valve seat and the second valve portion, respectively, and a piston disposed in the command cavity and a solenoid valve. The solenoid valve normally prevents main cavity-command cavity fluid flow to engage the poppet with the valve seat by fluid pressure acting on the poppet in the main cavity and permits the main cavity-command cavity fluid flow when energized to disengage the poppet from the valve seat by balanced fluid pressure acting on the poppet in the main cavity and on the piston in the command cavity to permit main cavity-outlet fluid flow.
