A flow control valve includes a housing defining a cavity therein. The housing has an input port for receiving a gas from a gas supply, and an output port for delivering the gas to a gas cylinder. The cavity defines a staging area fluidly connected to the input port, a delivery area fluidly connected to the output port, and a pressurization area fluidly connected to a feedback sensing port. The feedback sensing port is configured to receive pressurized fluid that is pressurized to a pressure level representative of a pressure level of gas delivered to the gas cylinder. The flow control valve includes a piston slidably positioned in a channel extending between the pressurization area and the delivery area. The position of the piston changes a rate of flow of gas through the flow control valve. The piston position moves in response to a pressure at the feedback sensing port.

Systems for filling a gas cylinder

An air compressor assembly may include a support structure, an operating unit including a compressor operatively connected to a motor through at least one drive belt, and at least one vibration isolator that is positioned between at least a portion of the support structure and at least a portion of the operating unit. The vibration isolator(s) is configured to dampen vibratory energy generated by the operating unit.

Vibration-dampening air compressor assembly

An air compressor assembly for filling self-contained breathing apparatus air containers has at least one condensate separator. The condensate separator includes a liquid-retaining vessel a liquid-level sensor. A drain valve is in fluid communication with the condensate separator. The drain valve is configured to open and drain retained liquid from the liquid-retaining vessel when the liquid-level sensor detects that a level of the retained liquid reaches a drain valve activation triggering level.

System and method for controlling moisture within an air compressor assembly

A cylinder filling system is configured to automatically fill fluid cylinders with fluid at varying fluid pressures. The cylinder filling system may include a plurality of pressure control manifolds operatively connected together and disposed in a fluid circuit between a fluid storage container and a fluid outlet. A control unit may be in communication with the plurality of pressure control manifolds. The control unit is configured to operate the plurality of pressure control manifolds to deliver fluid at a rated fluid pressure of a fluid cylinder that connects to the fluid outlet.

System and method for automatically filling fluid cylinders

A modular manifold assembly is configured to connect to a manifold block of an auto cascade system used to fill an individual fluid tank. The modular manifold assembly may include a main housing that contains one or more sequence valves and fluid conduits. The sequence valve(s) are configured to allow fluid to be sequentially drawn from a plurality of fluid storage cylinders.

Modular manifold assembly for sequentially drawing fluid from fluid storage tanks

Gas-filling system including a base manifold having a flow-control component and a manifold body that is operably coupled to the flow-control component. The manifold body includes a fill port and first and second supply ports that open to an exterior of the base manifold. The first and second supply ports are in fluid communication with a common passage within the manifold body such that the gas flowing through the first supply port or through the second supply port flows through the common passage to the fill port. The fill port is configured to be in fluid communication with a container. The gas-filling system also includes an accessory module removably coupled to the manifold body. The accessory module is connected to the first supply port and has an inlet port.
