Vacuum Angle 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, an elastomer 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. Htc offers a wide variety of valve types in a comprehensive range of sizes. They are manually and pneumatically, with bellows and without bellows. Port terminations are available in KF, ISO, CF, and Tube End. Htc designs all series angle valves suited for vacuum applications with venting processes, high vacuum applications in pumping systems, semiconductor technology, research systems, etc.
