Abstract: A valve for regulating the flow of fluid through an access port in a fluid chamber includes a body having a first end and a second end, the second end being located in the access port and the first end protruding outside of the access port. An axial bore extends from the first end to the second end, an injection fitting is formed at the first end of the body in fluid communication with the axial bore, and the second end of the body includes a selective sealing interface. The body forms a sealing interface with a threaded inner wall surface of the access port. A one-way valve assembly is positioned within the axial bore, and is arranged to permit a flow of fluid therethrough in a downstream direction and prevent the flow of fluid therethrough in an upstream direction. A bypass passageway extends from the selective sealing interface separate from the axial bore. A connecting passageway connects the bypass passageway with the axial bore upstream of the one-way valve assembly.

Abstract: When sample collection cylinders get full, they need to be switched out with empty sample collection cylinders. The connection between the sample cylinder and a piping system is often a quick-connect which typically has a high pressure rating when closed and a lower pressure rating when opened. The bleeder valve of the present invention, when installed in the piping system between the quick-connect and the sample cylinder can be used to reduce the pressure in the system and the quick-connect to rated pressures before the quick-connect is opened. In an alternative embodiment intended for service with hazardous materials, the bleeder valve and seals are formed from resistant materials and the vent is connected to a flare or other suitable point of disposal.

Abstract: A compressed gas supply system is disclosed which includes a pressure tank for a predetermined compressed gas. An outlet valve is mounted on the pressure tank and includes at least two outlet ports. One outlet port is provided with a size and thread configuration proportioned to meet a first industry standard for connection of equipment using the compressed gas within the tank. The other port has a size and thread configuration different from the one port, and proportioned to meet a second different standard for connection of equipment using the compressed gas. An automatic pressure-regulating valve is provided in one of the ports to reduce the pressure delivered to such port to a maximum pressure less than the maximum pressure allowable in the associated outlet port. The valve reduces the inventory requirements by permitting the use of a single valve and tank combination to connect with distribution systems for the compressed gas having different maximum pressure values.

Abstract: Instead of the usual three or five valves a valve manifold includes four valves, namely a pair of line block valves intersecting a longitudinally extending flow passage in the valve body for normally closing inlet passages, an equalizer valve between the line block valves intersecting the flow passage; below the equalizer valve is a vent passage and a vent valve in the vent passage. During operation the line block valves are open to promote the flow of process pressure to the measuring instrument and the equalizer valve is closed to prohibit the flow along the longitudinally extending flow passage. The vent valve is in the open position. By closing the line block valves with respect to the inlet passages, while leaving them open with respect to the flow and outlet passages, closing the vent valve and opening the equalizer valve permits the flow to be balanced between each side of the manifold. Upon opening the vent valve the manifold can be vented.
