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.

Abstract: A shut-off valve for use in a fluid transport or storage system includes a body defining an inlet port, an outlet port, and a fluid flow passageway extending between the inlet port and the outlet port, a seat arranged in the body adjacent the outlet port, a shaft at least partially disposed in the body, and a control assembly disposed in the body and operatively coupled to the shaft. The control assembly is movable between a closed position, in which a portion of the control assembly sealingly engages the seat to seal the outlet port, and an open position, in which the control assembly is spaced away from the outlet port and substantially outside of the fluid flow passageway, such that the control assembly provides minimal flow-restriction to fluid flowing through the fluid flow passageway.

Abstract: A flow path velocity modifier allows a control member of a control valve to operate very close to a seat ring while reducing or eliminating restricted flow areas, which results in greatly reduced flow velocity fluctuations, which results in smoother flow, between the sealing element and the seat ring. As a result, sealing elements made of relatively soft materials may be used without fear of damage from high flow velocities.

Abstract: A valve assembly including a valve body having a first pressure chamber and a second pressure chamber, the pressure of the first pressure chamber being lower than that of the second pressure chamber. The pressure of the second pressure chamber is discharged to the first pressure chamber in response to the change of the pressure of the first pressure chamber. A blocking device is arranged between the first pressure chamber and the second pressure chamber. A valve stem is arranged in the valve body with one end movably contacting the blocking device. A diaphragm is connected to the valve stem and is arranged adjacent to or above the first pressure chamber. When the pressure of the first pressure chamber is changed, the diaphragm forces the valve stem to move by sensing the pressure change of the first pressure chamber.
