Provided is an enclosure with an integrated hydrant. The enclosure includes a fluid flow conduit that transfers fluid from a fluid supply tube to a fluid outlet, which may be associated with the backflow preventer. The enclosure has a conduit that carries water from the fluid supply tube to the backflow preventer. Thus, a lower profile, lighter, and more aesthetically pleasing enclosure is provided.

An isolation valve can be used subsea such as with a fluid handling system which may be associated with a subsea Christmas tree and comprises a housing comprising a material created by a sintering process and a vertical axis defined in-between a first housing end and a second housing end; two or more seats comprising a sintered material and disposed radially opposite each other; a first annulus extending through a predetermined portion of the second housing end and the first seat at a first position radially offset from and substantially parallel to the vertical axis; a second annulus extending through a predetermined portion of the second housing end and the second seat at a second position radially offset from the first annulus along the vertical axis and substantially parallel to the housing vertical axis; a first fluid port disposed through the second end of the housing and in fluid communication with the first annulus; second fluid port disposed through the second end of the housing and in fluid communication with the second annulus; and an actuator disposed at least partially within the housing and rotatable about the vertical axis of the housing, the actuator comprising a sintered material, the actuator configured to allow fluid flow in a first rotational position of the actuator and block fluid communication in a second rotational position of the actuator, and a predetermined surface uniformly machined to a surface of the first seat which is exposed to the fluid annulus and to a surface of the second seat which is exposed to the fluid annulus, the predetermined surface defining a metal-to-metal seal at the exposed surfaces of the first seat and the second seat when the actuator is in the second rotation position.

A sub-surface safety valve having a positional flapper, a valve seat, and a remotely actionable opening prong. The opening prong comprising at least one of a debris wiper, filter, and at least one flow hole. The wiper, filter, and at least one flow hole function according to either position or movement of the flapper and opening prong and prevent debris buildup around the valve seat. The wiper is an extendible material in communication with the valve seat and a surface of the opening prong and it extends radially in response to closing the valve. The extension of the wiper in response to closing the flapper cause the wiper to scrape the surface of the valve seat. The filter can comprise a screen integrated with or attached to the opening prong. The flow holes can be in the form of angled flow holes or elongated slots.

Provided are systems and methods incorporating design features that may be beneficial over current available well safety valves, such as a sleeved receptacle for a piston, a constrained piston rod, and a trapped flapper valve. A safety valve may comprise: an outer housing having a central bore extending axially through the outer housing, wherein the outer housing comprises an outer wall having a receptacle formed in the outer wall; a sleeve disposed in the receptacle; a piston disposed in the sleeve, wherein the piston is actuated to travel in the sleeve; a spring positioned to apply a biasing force to the piston; and a valve member disposed in the outer housing, wherein the valve member is operable to selectively restrict flow through the safety valve in response to movement of the piston.

An apparatus and kit are provided for remotely controlling the flow of a valve in a faucet or shower. The user may remotely control flow by actuating a foot pedal, which pulls a cable causing the valve to open. When the cable is released, springs force the valve closed. Temperature may be remotely controlled as well by the actuation of a separate foot pedal, in which rotation of the foot pedal is transferred by cables to cause rotation of the valve and the corresponding temperature change of the flow.

Disclosed is a trigger valve methods, use and apparatus. The valve has a housing enclosing, at least in part, a cavity. There is a trigger poppet including a poppet sealing portion at least in part within the cavity, the trigger poppet configured to receive an external input at, or toward, a receiving end thereof. A trigger piston including a primary sealing portion and a major face at least in part within the cavity, the trigger piston configured to receive high pressure fluid therethrough, the trigger piston having a minor face opposite the major surface and a secondary sealing portion. The trigger poppet and trigger piston are biased towards each other at least by the high-pressure fluid acting on the minor face, such that the high-pressure fluid is sealed from the cavity by the poppet sealing portion and primary sealing portion in sealing engagement on each other. The secondary sealing portion sealing against the housing, or part thereof, preventing release of the high-pressure fluid therefrom. The poppet sealing portion when displaced from the primary sealing portion by the external input unseals the sealing engagement and allows high pressure fluid to flow into the cavity and act on the major face causing the trigger poppet to move and unseats the secondary sealing portion from the housing, or part thereof, to allow flow of high pressure fluid to then do work, or cause work to be done.

This invention relates generally to the dispensing of a fluid. More specifically, the invention relates to an apparatus and method for remotely controlling the flow of an effluent fluid stream from a dispensing hose of a fluid dispenser. An actuator controls at least one valve assembly of the fluid dispenser and comprises a generator located remotely of the at least one valve assembly, for generating a low-pressure signal, and at least one receiver in fluid communication with the generator for receiving the low pressure signal of each receiver operably associated with each valve assembly. The actuator also facilitates the simultaneous, sequential and alternate control of the at least one valve assembly.
