Methods of making and using the valve are also contemplated.

A seal assembly for use in a fluid valve includes: an actuatable valve body configured to open and close at least one connection of the fluid valve; at least one seal configured to sealingly abut against the valve body at one side of the valve body and to sealingly abut against a valve housing of the fluid valve at another side of the valve body; and at least one elevation from a lateral surface of the valve body integrally formed on the valve body sectionally, the at least one elevation being configured to activate the seal in a closed position of the fluid valve.

A flush valve includes a valve housing defining a fluid passageway between a fluid inlet and a fluid outlet. The fluid passageway includes a diaphragm valve seat disposed between the fluid inlet and the fluid outlet. The flush valve additionally includes a diaphragm assembly including a diaphragm and a disc. The diaphragm includes a primary opening and a bypass opening. The primary opening receives the disc therein and the bypass opening allowing water under pressure supplied to the fluid inlet to pass from a fluid inlet side of the diaphragm into a chamber in the fluid passageway. The flush valve additionally includes a relief valve configured to selectively control fluid flow from the chamber to the fluid outlet. The relief valve comprises a stationary valve element and a rotatable valve element each having at least one opening and being rotationally positionable relative to one another to regulate fluid flow.

An angle valve structure includes an angle valve body. The angle valve body is provided with a water inlet channel, a water outlet channel and an accommodation cavity. The accommodation cavity is rotationally provided with a valve core. One end of the valve core exposed outside the accommodation cavity is fixedly connected with a knob. The valve core is provided with a sealing block for sealing the water outlet channel when sealing. The valve core includes a main body part and an elastic arm whose one end is connected with the main body part. One side of the main body part is provided with a mounting slot for placing the sealing block, one side of the elastic arm is provided with an extrusion portion, and the other side of the elastic arm is provided with a contact portion against the sealing block after assembly.

A high pressure valve includes a valve body having a surface defining a corresponding portion of a conduit and a pocket. A removable insert is removably inserted into the pocket of the valve body and has surface defining a corresponding portion of the conduit. A seal insert is spaced from the valve body by the removable insert and has an interface with the removable insert. A moving member interfaces with the seal insert for selectively closing the conduit, the interface between the seal insert and the removable insert allows play between the seal insert and the removable insert in response to movement of the moving member.

An inflation hub includes a body having an internal lumen defining first and second lumen sections. A stopcock valve Chas a stem extending from the body between the first and second lumen sections, the stem being selectively rotatable between an open position, wherein an internal channel thereof fluidly connects the first and second lumen sections together, and a closed position, wherein the stopcock valve fluidly disconnects the first and second lumen sections from one another. A pressure-relief valve is integrated within the stem of the stopcock valve and in fluid communication with the internal channel thereof, and includes a loading member biasing the pressure-relief valve into a closed position. The pressure-relief valve moves into an open position when the stopcock valve is in the open position thereof and a pressure with the internal lumen of the body exceeds a threshold, opening pressure of the loading member.

An exemplary compounding system and device for mixing materials can include a housing, a first material source and a second material source. A first fluid line can be operationally connected to the housing and configured to transport a first volume of fluid per unit time from the first material source to a final container. A second fluid line can be operationally connected to the housing and configured to transport a second volume of fluid per unit time from the second material source to the final container. The device can also include a pump system including, a first pump having a first rotor and a first platen which secures the first fluid line between the first rotor and the first platen, the first pump being configured to move the first volume of fluid through the first fluid line, and a second pump having a second rotor and a second platen which secures the second fluid line between the second rotor and the second platen, the second pump being configured to move the second volume of fluid through the second fluid line. A first platen lock can be provided and can be rotated in a first direction to lock the first platen in a closed position relative to the first rotor, and wherein rotation of the first rotor draws the first material source through the first fluid line. The pump system can also be configured such that the volume of fluid per unit time delivered by the first and second pumps is different, and/or where the first and second pumps have different head characteristics.
