Bakeable all-metal valve is one type of the poppet valves. When the poppet is moved toward the top of the valve, the internal body cavity is open to the system, and flow is unimpeded (maximum conductance). Once the actuator moves the poppet to the bottom of the valve, a copper gasket sealing ring is compressed onto the sealing surface of the lower body of the valve. This action creates a vacuum tight seal and stops the flow. We offers the bakeable all-metal valves are designed to use for use in ultrahigh vacuum environment where elevated temperatures preclude the use of elastomers and low temperature gasket metals. We designs all series angle valves suited for vacuum applications with venting processes,high vacuum applications in pumping systems, semiconductor technology, research systems, etc.
