摘要： A flow control device includes a housing with an inlet and an outlet and a flow conduit disposed in the housing. The inlet, the flow conduit, and the outlet define a flow passage. A valve seat is disposed in the housing downstream of the inlet, and a shuttle is movably disposed in the housing and displaceable between a closed position engaging the valve seat to close the flow passage and an open position spaced from the valve seat to open the flow passage. A sealed chamber is defined between the housing and the flow conduit. A port coupled with a source of pressurized fluid communicates with the sealed chamber, where the shuttle is displaceable between the closed position and the open position based on a pressure in the sealed chamber. The threshold water pressure for displacing the flow conduit may be adjustable by modifying the pressure in the sealed chamber.

摘要： A hydraulic control system includes an oil control valve to control oil flow within a valve train. The control valve varies the flow rate to actuate an engine component from a first position to a second position based upon fluid pressure from the control valve. Varying the flow rate through the control valve includes increasing the flow rate through the control valve to increase the pressure to a first level to actuate the engine component to the first position. After the engine component is actuated, the flow rate through the control valve is maintained at a level sufficient to maintain the engine component in the first position. To actuate the engine component to the second position the flow rate through the control valve is then decreased. The fluid flow rate through the control valve is then maintained at a level sufficient to maintain the engine component in the second position.

摘要： A fluid pressure reducing valve apparatus includes a pressure reducing valve. The valve has: a body containing a fluid-flow chamber, a liquid supply orifice into the chamber, a liquid outlet from the chamber, a regulation plate opposed to the orifice, a spring acting to urge the plate towards the orifice, and a diaphragm between the plate and the body to close the chamber between them. A controllable motor drive acts between the body and an end of the spring remote from the plate. A flow meter is positioned downstream of the outlet. A controller is arranged to receive flow data from the flow meter and to control the motor drive for withdrawal of the remote end of the spring in accordance with flow rate measured by the flow meter. For an increase in demand flow, the plate is partially withdrawn to maintain downstream pressure on such increase and vice versa.

摘要： The disclosure relates generally to pressure regulators, and more particularly, to pressure regulating valves. In one illustrative but non-limiting example, a pressure in a flow channel is translated into a position of a diaphragm, wherein the position of the diaphragm is dependent on the pressure in the flow channel. The position of the diaphragm is then sensed. A position of a valve in the flow channel is then controlled to adjust the pressure in the flow channel acting on the diaphragm so that the sensed position of the diaphragm is driven toward a predetermined position. This may result in regulated pressure in the fluid channel.

摘要： A method of managing fluid supply in a process control system is provided. The method includes identifying, via a controller of a pilot device, a predetermined minimum source pressure, the predetermined minimum source pressure being the minimum pressure required at a fluid supply source to permit a simultaneous operation of all of a plurality of process lines. The method also includes determining, via the controller, whether a pressure of the fluid supply source is less than the predetermined minimum source pressure. The method further includes determining, via the controller, that the fluid supply source is to be changed when the pressure of the fluid supply source is less than the predetermined minimum source pressure.

摘要： A valve unit for modulating the delivery pressure of a gas. The valve unit delivers a gas flow and has a servo-valve with a first closure element and a tapping duct. The valve unit further has a pressure regulator associated with the servo-valve and including a valve seat mounted in the tapping duct and a respective second closure element associated with the seat, as well as an actuator associated with the second closure element, and a control circuit for generating a control signal for the actuator. The movement of the second closure element relative to the corresponding valve seat is correlated proportionally with the actuator-control signal so that, for a pre-selected signal value, a corresponding control-pressure value is generated so as to modulate the delivery pressure in a proportionally correlated manner.
