| PURPOSE:To permit pressure in the interior and exterior of a main valve to be balanced with each other forcibly to improve operation factor by providing a communicating hole in the main valve to which is connected an auxiliary valve for opening and closing this communicating hole and which is operated by connecting the auxiliary valve to a drive source. CONSTITUTION:When difference of pressure between the interior and exterior of a main valve 28 is 15-20kg/cm<2> and current is supplied to a coil 36, an auxiliary valve 29 is pivoted about a fulcrum 29b counterclockwise to open a communicating hole 28a in the main valve 28 for achieving forcibly pressure balance. When current to the coil 36 is stopped, the auxiliary valve 29 is pivoted clockwise about the fulcrum 29b to open the communicating hole 28a in the main valve 28. Thus, high pressure and low one communicate to each other to achieve forcibly pressure balance, and thereafter the main valve 28 is pivoted about a pivot 28b by the action of a tension spring 30 until the communicating hole 28a is closed, so that a return valve is changed over. | ||||||

| A valve has a valve piston (12) guided longitudinally movably in a valve housing (10) and actuated by an operation device (14). In one valve piston position, a connection is produced between a pressure supply port (P) and a working port (A). In another valve piston position, a further fluid-conducting connection is produced between the working port (A) and a tank port (T). The pressure difference arising between the working port (A) and the tank port (T) as flow passes through the further fluid-conducting connection acts, by an actuation device (30), on the valve piston (12). The valve piston passes from a stop position (32), with the further fluid-conducting connection shut off, into a fully open opening position with an enlarged opening cross section from working port (A) to tank port (T). | ||||||

A primary static seal is positioned to seal a static leak path between the packing ring and the valve body. A secondary static seal is spaced axially apart and functionally independent from the primary static seal and positioned to redundantly seal the static leak path. | ||||||

The valve cage can include a throttle section configured to provide pressure-reduced flow rates of the processing fluid, the throttle section having multiple throttle conduits extending from an inside of the valve cage to an outside of the valve cage; a high capacity flow section adjacent to the throttle section in the displacement direction, the high capacity flow section configured to provide increased flow rates of the processing fluid; and at least one equalization channel formed in the valve cage and extending from the inside to the outside of the valve cage, the at least one equalization channel leading from the high capacity flow section to the throttle section such that, before the valve member releases all throttle conduits, the equalization channel is released. | ||||||

| A gate valve assembly 100 comprises a valve body 20 with an inlet 22 and an outlet 23 and first and second valve elements 31, 33 which are located between the inlet 22 and the outlet 23. The first valve element 31 is engageable with and disengageable from the second valve element 33. The second valve element 33 is in sliding contact with the valve body 20 and is slidable between a first position in which the second valve element 31 prevents flow from the inlet 22 to the outlet 23 and a second position in which the second valve element 31 permits flow from the inlet 22 to the outlet 23. An actuator 12 is operable to move the first and second valve elements 31, 33. The assembly 100 is configured to provide a first flow path from the inlet 22 to the outlet 23 when the first valve element 31 is disengaged from the second valve element 33, and to provide a second flow path from the inlet 22 to the outlet 23 when the second valve element 33 is moved from the first position to the second position. Upon operation of the actuator 12 to open the valve assembly 100, initially the first valve element 31 disengages from the second valve element 33 to permit fluid flow through the first flow path in order to equalise upstream and downstream pressure on the second valve element 33. Further operation of the actuator 12 slides the second valve element 33 from the first position to the second position to permit fluid flow through the second flow path. | ||||||

| A fluid flow control device includes a valve body, a valve seat disposed within the valve body, and a valve cage coupled to the valve seat within the valve body. The fluid flow control device also includes a gland defined by the valve body, the valve seat, and the valve cage. The valve body has a first thermal expansion coefficient and the valve seat and/or the valve cage have a second thermal expansion coefficient different from the first thermal expansion coefficient. The fluid flow control device further includes a sealing assembly disposed within the fluid flow control device to provide a seal between the valve body and the valve cage. The sealing assembly exploits differential thermal expansion between the valve body and the valve cage in a direction parallel to the longitudinal axis and in a direction transverse to the longitudinal axis to improve the seal. | ||||||

| A gate valve includes a body with a flow passage intersected by a gate cavity and a gate with an axis, the gate being axially movable in the gate cavity between a gate closed position and a gate open position. A lifting device is in engagement with a stem of the gate to move the gate to the gate open position. A port extends from a first external surface of the gate to a second external surface of the gate. A seal member is mechanically connected to the lifting device, the seal member being moveable in response to axial movement of the lifting device between a seal open position where fluids can flow through the port and a seal closed position where the seal member blocks fluids from flowing through the port. | ||||||
