A flow path insert for a fluid control assembly includes an upstream portion and a downstream portion integral with the upstream portion. The upstream portion includes an upstream peripheral surface and the downstream portion includes a downstream peripheral surface. The upstream portion and the downstream portion cooperate to define an inlet passage and an outlet passage in fluid communication with the inlet passage. The inlet passage defines a first axis and the outlet passage defines a second axis that is transverse to the first axis. When the flow path insert is positioned within a body of a fluid control assembly, the upstream peripheral surface is in contacting engagement with the body and the downstream peripheral surface is spaced from the body. At least the downstream portion of the flow path insert and the body cooperate to define an annular passage in fluid communication with the outlet passage. Fluid control assemblies are also disclosed.

Fluid control assemblies and flow path inserts

A gas cylinder dispensing valve having an internal flow path provided with a pressure regulator. An isolation valve is provided within the flow path between the pressure regulator and a gas inlet of the valve and a flow control valve is provided within the flow path between the pressure regulator and a gas outlet to discharge the gas. Both isolation valve and the flow control valve can be manipulated by a single control knob which when set in an off position closes the isolation valve. The control knob can be rotated from the off position to select discrete, calibrated flow rates or an auxiliary position in which gas may be dispensed at a regulated pressure from an auxiliary outlet port.
