A fluid delivery device includes a tube coupled to an axial manipulator. The axial manipulator includes an elongate member arranged to move axially in a housing. The tube is in fluid communication with a fluid diverter which is arranged to move axially in the housing upon axial movement of the elongate member. Seals are provided to prevent fluid from leaking out of the housing. A fluid port is in fluid communication with the tube via the fluid diverter, such that fluid can flow in and out of the tube via the fluid port and the fluid diverter.

An energetic one way sequence termination arrangement may comprise a housing, a first inlet in operable communication with the housing, a second inlet in operable communication with the housing, and an outlet in operable communication with the housing. The energetic one way sequence termination arrangement is configured such that the second inlet is blocked from fluidic communication with the outlet in response to a first signal being received at the first inlet before a second signal is received at the second inlet, and the first inlet establishes fluidic communication with the outlet in response to the second signal being received at the second inlet before the first signal is received at the first inlet.

A meter bypass adapter has a body having: a first port; a second port; a third port; and a fourth port. At least one valve element is held by the body and moveable between: a first position wherein a flowpath is open from the first port to the second port and a flowpath is open from the third port to the fourth port without a direct flowpath from the first port to the fourth port; and a second position wherein a flowpath extends from the first port to the fourth port bypassing the second port and the third port. A single rotary actuator is held by the body to rotate about an axis and, in turn, shift the least one valve element between the first position and the second position.

A valve includes a valve stem having a shaft and including first and second poppet members with a seal portion extending radially outward from the shaft and disposed on the shaft between the poppet members. The valve further includes a valve body having a valve bore within which the valve stem is disposed for reciprocating axial movement and includes first and second ports that defining passageways through which gas or liquid may flow into or out of the valve bore. The valve body further includes first and second valve seats against which the first and second poppet members selectively seal with the seal portion being in sealing engagement with the valve bore between the ports.

A universal high-speed rotary union including an input manifold having passageways, an input distributor fixedly coupled to the input manifold and having passageways fluidly connected with the passageways of the input manifold, a valve plate fixedly coupled to the input distributor and having passageways aligned with the passageways of the input distributor, an output manifold rotatably coupled to the input manifold by a first bearing and having passageways and an internal housing; an output receiver slidably coupled to and disposed within the internal housing of the output manifold, and having passageways aligned with the passageways of the output manifold, a bore defined along a common axis of the input manifold, the input distributor, the valve plate, the output manifold, and the output receiver, and a shaft rotatably coupled within the bore by at least a second bearing. The valve plate and the output receiver have a metal to metal interface.

A valve comprises a housing in which a movable valve element having first and second valve members is disposed. A plurality of ports are disposed in the housing, and first and second seal portions are connected to the housing. At least one of the first seal portion and the first valve member is deformable such that, when only the first seal portion is in a sealed configuration with the first valve member, deformation allows the second seal portion to be brought into a sealed configuration with the second valve member, and/or at least one the second seal portion and the second valve member is deformable such that, when only the second seal portion is in a sealed configuration with the second valve member, deformation allows the first seal portion to be brought into a sealed configuration with the first valve member.

The flow path switching valve includes (a) a valve body having an open flow path which opens on a predetermined surface over a predetermined length in a predetermined direction, (b) a main body having a plurality of ports which open on a facing surface facing the predetermined surface at an interval shorter than the predetermined length in the predetermined direction, and a plurality of connection flow paths connected to the plurality of ports, (c) plate springs attached on both ends of the valve body in the predetermined direction so as to support the valve body such that a predetermined gap is formed between the predetermined surface and the facing surface, the plate springs applying elastic force onto the valve body according to a movement amount of the valve body in the predetermined direction, and (d) an actuator which drives the valve body back and forth in the predetermined direction.

A valve including a valve seat assembly that includes a first valve seat sealing member positioned between a first valve seat retaining ring and a first radially inwardly extending flange that extends from an inner surface of a hollow valve retainer, and a second valve seat sealing member positioned between a second valve seat retaining ring and a second radially inwardly extending flange that extends from the inner surface of the hollow valve retainer. A valve member is configured to engage and disengage with the first and second valve seat sealing members to permit fluid to travel from a fluid inlet to a fluid outlet.

A double action directional fluid flow valve includes a stepped piston connected with a poppet valve and moveable by a controller between open and closed positions by applying a continuous pressure to a small diameter piston face and selectively applying and removing pressure from a large diameter piston face to move the poppet valve between an open position and a closed position.

A meter bypass adapter has a body having: a first port; a second port; a third port; and a fourth port. At least one valve element is held by the body and moveable between: a first position wherein a flowpath is open from the first port to the second port and a flowpath is open from the third port to the fourth port without a direct flowpath from the first port to the fourth port; and a second position wherein a flowpath extends from the first port to the fourth port bypassing the second port and the third port. A single rotary actuator is held by the body to rotate about an axis and, in turn, shift the least one valve element between the first position and the second position.
