Abstract: A fluid coupling has two similar coupling halves, each with a rotary body of a valve. A drive device for closing/opening the valve is associated with each rotary body. Each half has a coupling means for connecting/decoupling the halves by relative rotation. Securing means secure the connection when at least one valve is open and close the two rotary valves to disconnect/connect the halves. The drive device is arranged on one half and has a drive shaft which is associated with a valve shaft of the rotary body of the other half. A locking connection is configured which, when the halves are connected, connects the drive shaft on one half to the valve shaft on the other in a non-rotatable/releasable manner such that the rotation of the rotary body is controllable and relative rotation of the halves is blocked but the relative rotation when the valves are closed is permitted.

Abstract: The present disclosure relates to coupling device and valve assembly for use with accessing the water flow in a fire hydrant. Specifically, the present disclosure relates to various coupling device and valve assemblies which are used as a quick connect and disconnect of a fire hose to the hydrant. Additionally, it is advantageous that the coupling device and valve assemblies also provide a self-sealing valve feature, which immediately stops the flow of water when the hose is disconnected from the hydrant. An advantage provided by the present coupling device and valve assemblies is that should a primary valve on a hydrant become unusable, the fire hose can be quickly disconnected from that hydrant and reconnected to a second hydrant without requiring a shutdown of the water grid feeding the disconnected hydrant.

Abstract: A valve assembly for mounting on a substrate via rotational engagement with a base of the valve assembly, and a cap for such a valve assembly. A body of the cap is rotatably engageable with the base between opposing first and second terminal ends. At each of the first and second terminal ends, the body and the base abut each other to prevent rotation between the body and the base. As a result, torque applied to the cap is transmitted to the base to vary rotational engagement of the base with the substrate. A slot formed in the cap may be suitable to receive a protrusion on the base and may fork into two separate portions that terminate in opposing terminal ends to allow selective engagement of the protrusion with the two portions. The protrusion abuts against the terminal ends to transmit torque from the cap to the base.

Abstract: A barrel valve assembly for a fluid distribution manifold. A barrel valve body has an off-axis passage with substantially linear walls therethrough, allowing for a substantially linear relationship between fluid flow through the body and angular rotation of the barrel valve within the manifold. The barrel valve thus requires a smaller working environment for the valve assembly, providing benefits in terms of assembly size and weight.

Abstract: A steam trap includes a replaceable condensate nozzle cartridge with a through passage forming a venturi nozzle in a straight-line working fluid flow path. The venturi through passage includes a venturi nozzle insert that reduces the pressure of the working fluid to cause the liquid water in the working fluid to flash and restrict the flow of steam through the passage. The condensate nozzle is located in a reduced pressure discharge chamber into which a nozzle outlet discharges water condensate extracted by the nozzle and emptied from a trap outlet. The reduced pressure discharge chamber has an access opening sealed by a removable cover to allow the nozzle cartridge to be removed and replaced if necessary, without removing the steam trap from the process line. Locating the removable nozzle cartridge in a lower pressure region of the steam trap overcomes rating limitations on prior steam traps with replaceable venturi nozzles.

Abstract: A valve core for a faucet includes a casing, an immovable plate, a movable plate unit, a bracket, and a lever. The movable plate unit includes two pairs of coaxial movable plates and dials. The movable plates are disposed on top of the immovable plate. A restricting mechanism is disposed between one dial and the casing, and another restricting mechanism is disposed between the other dial and the bracket. When the lever is opened, the restricting mechanism is unlocked, and the lever is rotated to adjust the water temperature of a manual spray mode of the faucet. When the lever is closed, the restricting mechanism is locked, and the lever is rotated to adjust the water temperature of an automatic spray mode of the faucet. The water temperature adjustments of the manual spray mode and the automatic spray mode are independent of each other.

The improved poppets and valve seats are useful for reducing or eliminating poppet leakage and high impact stresses on the sealing surfaces of the poppets, and are especially intended for use with high-speed reciprocating compressors operating at 1000 rpm and higher. A control chamber spacer plate for creating a control pressure chamber within the unloader valve assembly, and a valve seat cushioning plate for reducing stress on the head ends of the poppets are also described.

Abstract: A rocker valve comprising a rocker valve mechanism in a valve body. The mechanism comprises a single pivot arm to which first and second plungers are pivotally fixed to act in opposition. The rocker valve includes a flexible seal member extending laterally across the first and second fluid ports and having a first sealing region attached to a plunger head of the first plunger and a second sealing region attached to a plunger head of the second plunger. When the single pivot arm is pivoted relative to the valve body, a rotation of at least one of the first and second plungers about its respective fixed pivot is constrained solely by the flexible seal member such that a lateral position of the plunger head is automatically adjusted by the flexible seal member to balance tensile forces in the flexible seal member around the plunger head.

Abstract: A singular piston included behind a valve seat within a gate valve assembly can be energized by external pressure through a hydraulic port within the valve body. When the back side of the singular piston is energized, the singular piston applies force in one direction against the adjacent valve seat, valve gate, opposing valve seat and valve seat pocket in both the valve open position and the valve closed position to block any unwanted matter from moving into the valve backside cavity. A singular piston has a pressure sealing surface and a piston pocket with an adjacent pressure sealing surface that allows the valve to seal in the closed position with the contained fluid bore pressure against the opposing valve body flow path side to the piston without the piston being energized.
