    Abstract: A valve device of the present invention includes: a main valve body interposed between a first pressure chamber of a main passage and a second pressure chamber; and a pilot valve body provided in the second pressure chamber. A first pilot passage including a first restrictor extends from an outside of a housing or a primary passage to the second pressure chamber, and a second pilot passage including a second restrictor is formed at the main valve body. The pilot valve body is maintained at a first operation position by a pilot valve body biasing member and is caused to move to a second operation position by a valve body driving unit. When the pilot valve body is located at the second operation position, the main valve body is caused to move to an open position by a pressure difference between the first pressure chamber and the second pressure chamber.

    Abstract: 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.
