High-pressure valves employ a non-rotating valve needle having a tapered tip, which may be selectively moved between seated and unseated positions relative to a valve seat in a valve chamber. The valve seat is tapered inwardly and has a smaller taper angle than the valve needle. The valve needle includes an enlarged cylindrical or spherical connecting end adapted to be received in the actuating stem bore and slot. This valve consists of a sealing for the needle, provided by a sealing medium comprised of a combination of seal member received between a pair of seal washers. The inlet passage into the valve chamber may be configured so as to receive and locate a replaceable seat member. An improved adjustable locking bracket is employed to retain the packing nut in a final adjusted position relative to the valve body.
High-pressure vaporizers are designed specifically for high-pressure gas applications including cylinder filling and laser applications. It comprises a number of individual multi-finned aluminum heat transfer extruded elements lined with a high pressure retaining stainless steel tube. Extrusions are connected in series. Liners are hydrostatically expanded into the extrusion element to ensure 100% contact and efficient heat transfer.
