Abstract: A valve assembly includes a valve body defining a cylindrical passage therein about an axis. An inlet port is defined in or near a first end of the valve body. First and second outlet ports are defined in the valve body extending radially outward from the cylindrical passage. A cylindrical valve spool having a central passage is positioned within, and sealingly engaged with, the cylindrical passage. The valve spool is moveable along the axis among: a first position wherein the inlet port is in fluid communication with the first outlet port but not the second outlet port, a second position wherein the inlet port is in fluid communication with the second outlet port but not the first outlet port, and an intermediate position between the first and second positions wherein the inlet port is in fluid communication with both of the first and second outlet ports.

Abstract: The decoking control valve includes a piston, a cylinder, and a hydraulic rod seal at the outlet ports. The piston can move translational inside the cylinder along a fixed direction. The cylinder houses the hydraulic rod seal in a groove of the cylinder that places the hydraulic rod seal next to the piston. The hydraulic rod seal has a seal ring in contact with the piston, and the seal rings are activated. As the piston translates within the cylinder, the seal ring will activate at one outlet port and allow fluid to flow out of another outlet port.

Abstract: Flow control systems and methods for controlling the flow of liquid into and out of a tubular member comprising a perforated portion that is configured to distribute a flow of liquid having a predefined fixed liquid pressure through the perforated portion to pressurize an intestine that is suspended on the tubular member is disclosed. The flow control system comprises a flow regulating valve having a slidably arranged valve structure arranged in a pressurized liquid filled water chamber and an elastic water-side diaphragm arranged in the water chamber and connected to the valve structure such that the water-side diaphragm allows the valve structure to be moved in a first direction along the longitudinal axis of the valve structure to increase the volume in the water chamber and be moved in the opposite direction to decrease the volume in the water chamber.

Abstract: A way valve (1) with a 5/2 way valve function has a valve member (13) moveable between two switching positions in a valve member accommodation space (8). The valve member (13) has a valve disk (49) arranged in an inlet section (24) of the valve member accommodation space (8) connected to a feed channel (36), the valve disk having an axially oriented annular valve member sealing surface (56) and being located opposite an annular body sealing surface (54) formed on the valve body (3). So as to close a fluid connection between the inlet section (24) and an attached outlet section (25, 26) of the valve member accommodation space (8) connected to a working channel (37, 38), the valve disk (49) is located with its valve member sealing surface (56) on the opposite body sealing surface (54). Either the body sealing surface (54) or preferably the valve member sealing surface (56) is formed on a collar-like, axially raised sealing edge (57), which has a non-circular, elongated shape, whereby the way valve (1) possesses a high power density.

Abstract: A control valve for a reverse osmosis water purifying system provides a feed water port, a squeeze water port, a drain port, and a product water connection, each of which open into a bore. A first, second, and third O-rings are located in the bore successively between the feed water port, the squeeze water port, the drain port, and the product water connection. A control piston is moveably located in the bore of the housing. The control piston includes a vent/drain well in which a side is chamfered and at least one recess disposed around an end of the control piston. The vent/drain well provides a fluid passage between the squeeze water port and the drain port when the vent/drain well passes over the second O-ring. The fluid passage includes an opening formed between the second O-ring and the chamfered side of the vent/drain well, where the size of the opening is responsive to the position of the control piston.

Abstract: A method of controlling an actuator includes switching a primary solenoid valve to a first mode to fluidically connect a supply pressure source to a control chamber of a pilot valve. A fluid from the supply pressure source is directed through the primary solenoid valve to fill the control chamber of the pilot valve and put the pilot valve in a first position. The first position fluidically connects a second chamber of the actuator to a return pressure source. The actuator includes a cylinder between the first chamber and the second chamber and a rod attached to the cylinder. The fluid from the supply pressure source is directed into the first chamber of the actuator to move the cylinder and the rod in a first direction while the pilot valve is in the first position.
