摘要： A 3-way valve for controlling the flow between first and second ports and a common port. The 3-way valve comprising a valve body having an integral flow portion and a valve stem having first and second valve members. The valve stem is pressfit assembled into the flow portion of the valve body where at least one of the first valve member and the flow portion momentarily deforms. The valve stem operates between a first position where fluid is allowed to flow between the common port and the second port and a second position where fluid is allowed to flow between the common port and the first port.

摘要： A bag-in-bag-in-bottle assembly formed by a flexible dispensing container with a dispensing fitment. The dispensing container is positioned adjacent or sandwiched between one or more flexible pressurization containers having a separate inlet/outlet path through a second fitment. The bag-in-bag assembly can then be placed in a containment vessel with the fitments mounted such that it is accessible on the vessel. A liquid can be extracted from the dispensing container by introducing a fluid into the pressurization container(s) with enough pressure to force the liquid out through the dispensing fitment. A contoured dispensing head may be coupled to the bag-in-bag-in-bottle assembly using a earn actuation arrangement for simultaneously locking the pressurization, vent and fluid extraction couplings.

摘要： The invention comprises a three-way diaphragm valve. The valve has a housing having three flow ducts each leading into an open interior chamber. The open interior chamber is divided into a central chamber, an upper chamber and a lower chamber. A first valve seat is positioned between the central chamber and the upper chamber. A second valve seat is positioned between the central chamber and the lower chamber. A central valve stem assembly is slidably mounted in the valve and has a first valve member and a second valve member positioned to alternately engage the first valve seat and second valve seat respectively, to direct flow from one passageway to another. A spring bears against the valve stem assembly to bias the relative position of the valve members and valve seats in a first predetermined position. An actuator comprising a piston is slidably mounted in a piston chamber and attached to the valve stem assembly to overcome the force of the spring and move the valve stem assembly into a second actuated position. The piston may be moved by pressurized air or hydraulic fluid to automatically actuate the valve into the second actuated position. Diaphragms are integrally formed on each valve member and attached to the valve body to form a barrier or outside walls of the open interior chamber to prevent fluid from leaking from the valve. An additional diaphragm may provide secondary containment of the spring to provide additional protection against contamination of the process fluid.

摘要： In one embodiment, a sight tube flowmeter is formed of a plurality of fluoropolymer components welded together to form a unitary flowmeter body. The components can comprise a PFA upright sight tube having two end portions, a flow conduit extending therethrough and two fitting portions that are uniquely welded onto each end of the sight tube, and a fluoropolymer float device movable to various positions within the flow conduit depending on the flow level of the fluid flowing therethrough. The float device can be of conventional design or for those flowmeter embodiments where low fluid flow rates are to be measured, an elongate float can be utilized. The floats and, in particular, a designated portion thereof, are visible through the sight tube to provide visual indication of the position, and thus the flow rate of fluid flowing through the flowmeter. In addition, alternative embodiments include the implementation of the unique sight tube and elongate float design in conventional flowmeters.

摘要： A valve manifold assembly including a manifold body defining a primary flow passage and a secondary flow passage fluidly coupled therewith through an aperture in the wall of the primary flow passage. A valve including a head portion and a stem extending therefrom is disposed through the aperture. The head portion has a valve sealing surface adjacent and extending around the stem, and a valve seat having a seat sealing surface facing into the primary flow passage extends around the aperture. The valve is selectively shiftable between a closed position wherein the valve sealing surface is sealingly engaged with the seat sealing surface to block fluid flow between the secondary flow passage and the primary flow passage, and an open position wherein the valve sealing surface is spaced apart from the seat sealing surface to enable fluid flow between the secondary flow passage and the primary flow passage.

摘要： An extended stroke poppet valve particularly suited for handling caustic fluids and having features enabling an extended service life for the valve. The valve includes a two part primary diaphragm assembly with a wetted diaphragm made from highly fatigue resistant fluoropolymer material, and a diaphragm backer made from high strength fluoropolymer material designed to withstand the high stress loads imposed by an extended valve stroke. The combination of these two layers in a single primary diaphragm assembly yields a highly durable, caustic chemical resistant, diaphragm capable of use in a long stroke poppet valve and having a relatively long service life.
