The present disclosure provides a pilot valve and a four-way reversing valve. The pilot valve includes: a valve body, wherein the valve body is a cylinder formed by integrally stretching and having an open end and a closed end, the closed end is defined as a first end, the open end is defined as a second end, the first end of the valve body is provided with an inlet, the valve body is internally provided with a cavity, and the inlet is in communication with the cavity; an inlet pipe, connected with the first end of the valve body, wherein a pipe opening of the inlet pipe is in communication with the inlet; and a limiting structure arranged between the first end of the valve body and the inlet pipe, the limiting structure is used for limiting a relative position of the inlet pipe relative to the valve body.

A hydraulic control circuit component such as a valve is configured which sliding surfaces. At least one of the sliding surfaces is configured as a single crystal material, such as ruby or sapphire.

Certain embodiments described herein are directed to manifolds that comprise a moveable, internal sealing member that can be used to engage one or more ports of the manifold and prevent or reduce fluid flow from the engaged port into the manifold. In certain examples, the manifold can be used in a mass spectrometer to control fluid flow from an interface and a turbomolecular pump.

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.

In accordance with an embodiment, a fluid delivery system is provided that includes a faucet body having opposing ends spaced apart by a channel and a universal adapter mated to one end of the faucet body and a spout mated to the other end of the faucet body. A diverter is connected to the spout. In accordance with another embodiment, a method for manufacturing a faucet includes providing a faucet having a diverter, wherein the diverter includes a cavity configured for reducing water pressure within the cavity and bonding a protective material to the faucet so that the faucet and the protective material form a unitary structure.

A multi-well pad for fracturing a subterranean formation can include a valve assembly that includes a shuttle valve, an inlet, a first outlet, and a second outlet, where the inlet is coupled to a fracturing pump, where the first outlet is coupled to a first well, where the second outlet is coupled to a second well, where first shuttle valve has a first position and a second position. The fracturing pump and the first well can form a continuous first path through the valve assembly while closing off a second path between the fracturing pump and the second well when the shuttle valve is in the first position. The fracturing pump and the second well can form a continuous second path through the valve assembly while closing off the first path between the fracturing pump and the first well when the shuttle valve is in the second position.

An electromagnetic actuator includes a pair of plate springs each of which is configured to produce elastic force in a predetermined direction in accordance with an amount of deformation; a movable member supported by the pair of plate springs to be movable in the predetermined direction; and a drive unit which is configured to drive the movable member in the predetermined direction in a non-contact state by means of electromagnetic force to be applied between the pair of plate springs in the predetermined direction.

A method of sequencing a pyrotechnic system includes igniting at least one of a first energetic coupled to a first inlet of a one way sequence termination arrangement, and a second energetic coupled to a second inlet of the one way sequence termination arrangement, fluidically coupling the first inlet to an outlet of the one way sequence termination arrangement in response to the second energetic being ignited before the first energetic is ignited, and blocking fluidic coupling between the second inlet and the outlet in response to the first energetic being ignited before the second energetic is ignited.

A dishwasher for treating dishes according to an automatic cycle of operation and including a tub at least partially defining a treating chamber, at least one sprayer configured to emit a corresponding spray of liquid into the treating chamber, at least one liquid circuit supplying liquid to the at least one sprayer, a pump having a pump inlet fluidly coupled to the treating chamber and a pump outlet, and a diverter valve controlling a flow of liquid from the pump to the at least one sprayer.

A valve assembly for modulating flow of a fluid through a valve may include a plunger, a flange with an orifice, a first disc with an orifice, a second disc, a gasket in contact with both the flange and the first disc, three bearing members disposed between the first disc and the flange. The three bearing members define a position and orientation of the first disc with respect to the flange, and separate the first disc from the flange, thereby defining a gap between the flange and said disc. The plunger displaces the second disc surfaces from a first position to a second position.
