Abstract:
A high pressure fluid 3-way control valve comprises a valve body defining a first port, a second port, and a third port, a throat disposed in flow communication with each of the first, second and third ports, first and second valve seats mounted in the throat of the valve body, a shiftable control element disposed having a first seating surface and a second seating surface and movable between a first position in which the first seating surface is seated against the first valve seat and a second position in which the second seating surface is seated against the second valve seat The first and second ports are in flow communication with one another via the throat along a second flow path when the control element is in the second position.
Abstract:
A high-pressure regulator (100) includes body (110) having a pressure inlet (112) and a pressure outlet (170). A piston (130) is disposed in the body and fluidly coupled to the pressure inlet and the pressure outlet. The piston is configured to operate in compression to contact a seat ring for the purpose of controlling the flow of fluid from the pressure inlet to the pressure outlet in response to a pressure applied to a surface of the piston via the pressure outlet. A piston seat (129) circumferentially engages the piston to provide an improved seal at low temperatures.

Abstract:
A control element (160) of a bi-directional valve is in fluid communication with an outlet pressure (200) and an inlet pressure (180) when the valve is closed such that a sum of the forces applied to the control element result in a net force urging the control element to seat against a valve seat (240). The valve includes a valve body (120) carrying the valve seat (240). The control element (160) is balanced on an outlet side of the valve seat such that the outlet pressure applies approximately no net force to the control element. In contrast, the control element is unbalanced on an inlet side of the valve seat such that inlet pressure applies a net force on the control element to bias the control to seat against the valve seat (240).

Abstract:
A fluid dispensing system includes a manifold having a fluid outlet port to dispense fluid from a plurality of fluid supply containers. The system additionally includes a plurality of valves connected to the manifold for controlling the flow of fluid from the containers. The manifold and valves are configured such that all fluid flow connections are disposed within the manifold, thereby reducing and/or eliminating the amount of piping required external to the manifold. So configured, the valves include simple cartridge-type devices that are easily installed into and removed from the manifold.

Abstract:
Diaphragm interface apparatus to improve a cycle life of a diaphragm are described. An example fluid regulator includes a fluid flow passageway between an inlet and an outlet, where a sensing chamber defines a portion of the fluid flow passageway. A diaphragm senses a pressure in the sensing chamber and a diaphragm interface adjacent the sensing chamber has a curved surface to contact a portion of the diaphragm that moves in response to pressure changes in the sensing chamber. The curved surface affects an amount of stress imparted to the portion of the diaphragm during operation of the fluid regulator.
