A spring return cartridge for a rotary actuated valve includes a torsion spring having a spring-loaded intermediate portion extending between first and second end portions and a spring carrier sleeved with the torsion spring. The spring carrier includes a first portion rotationally fixed with the first end portion of the torsion spring, and a second portion rotatably coupled with the second end portion of the torsion spring, such that the second end portion of the torsion spring is rotatable with respect to the spring carrier, and with respect to the first end portion of the torsion spring, between first and second rotational limit positions, with the intermediate portion of the torsion spring biasing the torsion spring second end portion to the first rotational limit position and maintaining a spring-loaded condition in the first rotational limit position.

Spring return valve handle arrangements

A push to connect fitting includes first and second fitting components and a conduit releasing insert. The first and second fitting components are assembled to define an internal cavity enclosing a conduit retaining arrangement axially movable between an outboard conduit gripping position and an inboard conduit releasing position. The conduit releasing insert includes a fitting interlocking feature releasably engaging the second fitting component, and a releasing feature engaging the conduit retaining arrangement to secure the conduit retaining arrangement in the conduit releasing position against axial outboard movement. Movement of the conduit releasing insert to disengage the fitting interlocking feature from the second fitting component permits outboard axial movement of the conduit retaining arrangement to the conduit gripping position.

Push to connect conduit fitting assemblies and arrangements

A flow sensing device includes a first body member defining an inlet port, an upstream sensor port, and a first connecting port; a second body member defining an outlet port, a downstream sensor port, and a second connecting port; a flow restricting element defining a flow restricting passage and including a first end connection coupled to the first connecting port and a second end connection coupled to the second connecting port, such that the flow restricting passage is disposed between the inlet port and the outlet port, and between the upstream sensor port and the downstream sensor port; a first fluid sensor assembled with the upstream sensor port; and a second fluid sensor assembled with the downstream sensor port.

Fluid monitoring module arrangements

A push to connect fitting includes first and second fitting components, a sealing arrangement, a gripping arrangement, and a colleting ring. The first fitting component has an outboard end that is adapted to receive a conduit end. The second fitting component is joined to the first fitting component to define an interior cavity. The sealing arrangement, disposed in the interior cavity, seals one of the first and second fitting components with an outer surface of a conduit end when the conduit end is inserted into the outboard end of the first fitting component. The gripping arrangement is disposed in the interior cavity, and the colleting ring is disposed in the interior cavity and has an inboard end surface engaging an outboard end surface of the gripping arrangement.

A fluid monitoring module includes a flow sensing device and a controller disposed in an enclosure. The flow sensing device includes a body including an inlet port, an outlet port, an upstream sensor port, a downstream sensor port, and a flow passage disposed between the inlet port and the outlet port, and between the upstream sensor port and the downstream sensor port. A first fluid sensor is assembled with the upstream sensor port, and a second fluid sensor is assembled with the downstream sensor port. The controller is in circuit communication with the first and second fluid sensors for receiving at least one of pressure indicating signals and temperature indicating signals from each of the first and second fluid sensors, and for measuring fluid data based on the received signals.

A fluid component includes a cross-shaped body having laterally extending first and second flow ports and axially extending first and second access ports. The first flow port connected in fluid communication with the first access port by a first branch port. The second flow port connected in fluid communication with the second access port by a second branch port. The first and second access ports are connected in fluid communication by a convoluted flow restricting passage extending generally axially from the first access port to the second access port.
