A faucet that includes a housing, a first valve, a handle body, a handle, and a second valve. The first valve is disposed at least in part within the housing and controls one of a flow rate and a temperature. The handle body has an elongated base, which extends from the housing along a longitudinal axis and is operatively coupled to the first valve, such that rotation of handle body about the longitudinal axis relative to the housing controls the first valve. The handle extends from the base along a radial axis relative to the longitudinal axis. The second valve is disposed at least in part within the handle and controls the other of the flow rate and the temperature, the second valve operatively couples the handle to the base, such that rotation of the handle about the radial axis relative to the handle body controls the second valve.

An apparatus for minimizing dead leg spaces in a container or tubing includes a first member having a flange for attaching the first member to a wall of the container or tubing, the flange having at least one aperture, and a second member rotatably coupled to the first member, the second member having an upper end having at least one aperture, and an open distal end. The second member is rotatable relative to the first member between a closed position where the at least one aperture of the second member is misaligned with the at least one aperture in the flange to prevent the passage of fluid, and an open position where the at least one aperture of the second member is aligned with the at least one aperture in the flange to allow for the passage of fluid.

An alfalfa valve telemetry system for regulating irrigation fluid to an irrigation-dependent field provides an alfalfa valve that operates over an opening to a fluid supply pipe in a field, so as to selectively discharge fluid to the field. The alfalfa valve telemetry system provides a telemetry-controlled valve actuation assembly that axially or pivotally displaces the alfalfa valve between an open position and a closed position over the opening in the pipe. A valve actuation assembly displaces the lid, axially, or pivotally, over the opening of the pipe. A mounting portion anchors the valve actuation assembly to the pipe. Environmental sensors and fluid sensors in the field communicate data signals with a primary controller that controls the valve actuation assembly. The position of the alfalfa valve is based upon the data signals received from the sensors, indicating fluid levels, fluid flow rate, and environmental conditions on and near the field.

A control structure capable of adjusting water volume and controlling water supply contains: a body, a fixer, a valve stem, an adjuster, and a controller. The body includes a water outflow segment for connecting with a watering tool, an accommodation groove for accommodating the fixer and the valve stem. The fixer includes a flexible retaining rib, and the valve stem includes an inlet communicating with the water outflow segment, a fixing rib, an opening communicating with the inlet, and a guiding column. The guiding column has a seal ring. The fixing rib retains with the flexible retaining rib so as to limit a rotation of the adjuster along the body. The adjuster includes a threaded orifice screwing with a screwing section of the controller, an inflow aperture fitting with the guiding column, and a shoulder formed beside the inflow aperture. The controller is coupled with a water supply pipe.

A multi-fitting rotatable fluid connection apparatus comprising a fluid entry fitting and first and second fluid discharge fittings. The fluid entry fitting comprises a first end connector threaded for attachment to a fluid source, and first and second distribution connectors. The first fluid discharge fitting has a first intake connector which receives fluid from the first distribution connector. A first rotation member is coupled between the first intake connector and the first distribution connector such that the first fluid discharge fitting is rotatable about a first axis of rotation. The second fluid discharge fitting has a second intake connector which receives fluid from the second distribution connector. A second rotation member is coupled between the second intake connector and the second distribution connector such that the second fluid discharge fitting is rotatable about a second axis of rotation.

A pressure relief valve is provided. The pressure relief valve includes a hollow body having an inlet and an outlet, with the hollow body including at least one aperture extending through a surface of the hollow body. An actuator assembly is attached to the hollow body and a sleeve is slideably positioned about the hollow body, with the sleeve moveably attached to the actuator assembly. During operation, the actuator assembly moves the sleeve from a first position that covers the aperture to a second position that uncovers at least a portion of the aperture.
