Abstract: The invention relates to a sanitary unit (1) comprising a pressure-reducing valve (2) that has a valve housing (3) containing a valve support (6) provided with at least one through-flow channel (7), said valve comprising a cup-shaped valve body (5) which is guided such that it moves from an open position against a restoring force into a closed position. In the closed position, the valve body (5) sits on a valve seat (11) provided on the valve support (6) with the circumferential edge (9) of its cup shape, in such a way that the valve body (5) blocks at least one channel opening (12) of the at least one through-flow channel (7). The sanitary unit according to the invention 54 is characterised, inter alia, in that the valve housing (3) has an external or internal thread (22) for screw connection to a coupling counterpart (23).

Abstract: A pressure-reducing valve includes a valve chamber, a pressure regulating chamber, a partition member, which has a communication hole, and a valve body. The partition member includes the communication hole and a valve seat. The valve body includes a body portion and a rod portion. The valve seat includes a plurality of inclined surfaces, which have different inclination angles with respect to the central axis of the valve body. The circumference wall of the communication hole and the valve seat are connected by a coupling portion. The inclination angle of the valve seat is varied discretely such that the valve seat comes into contact with the valve body at a position more that is further the radially outward from the central axis of the valve body than the coupling portion.

Abstract: A need exists for a tank regulator that can reduce a pressure of more than about 4,300 psi to a much lower pressure. The present disclosure describes a piston regulator that allows for pressure to be reduced from an inlet pressure of about 5,000 psi or more to outlet pressure of about 2,000 psi or less. The regulator includes intermediate chambers to provide step-down pressures along the piston. The internal chambers enable to hold pressure differentials between the high-pressure inlet and the low-pressure outlet. The pressure in the intermediate chambers is maintained by a pressure-limiting valve to control the pressure differentials across piston seals. These seals allow the piston to actuate while maintaining a seal between the various pressure chambers.

Abstract: A pressure limiting valve communicates between a closed state, where a ball is biased against a valve seat along a contacting line and, an open state, where the ball is at a distance of the valve seat enabling fluid under pressure to exit via a relief orifice opening in the valve seat. The valve seat is shaped so that in the closed state of the valve, the contacting line between the ball and the valve seat is at a distance from the relief orifice opening.

Abstract: A driving apparatus and a valve including the same. The driving apparatus senses a pressure of a fluid medium and generates a driving force. The driving apparatus includes: a drive shaft, a sensing device, a limiting device, a support body, and a protruding member. The limiting device includes a groove, and the protruding member is engaged in the groove. The limiting device can thus automatically limit the rotation of the drive shaft, so as to avoid damaging the sensing device, thereby facilitating maintenance and installation of the valve.
