带减压旁路的埃斯托尔高导阀 VAHCK150V1

描述

The High Conductance Valve with one or two pressure reduction bypasses is made from 304 stainless steel and has 2 DN 40 CF, 2 ¾ inch ConFlat (CF) flanges. Each pressure reduction bypass has a Swagelok bypass valve and a flow control orifice. The high conductance valve is sealed with an Elastomer poppet seal. The vacuum side of the valve connects to the RGA chamber and the high-pressure side connects to the customer’s process chamber. In a dual bypass model, when all three valves are closed (Hi-C and 2 Swagelok), the RGA is isolated from the process chamber. Opening either pressure reduction valve allows the RGA to sample the customer’s high-pressure process through a flow restricting aperture. The aperture(s) may be sized for processes that operate at different pressures. If the process chamber base pressure is low enough, the high conductance valve may be opened to measure the background gasses or for leak checking the process chamber. Stainless steel mounting hardware is included with copper gaskets for the CF flanges and extra VCR gaskets for the bypass valves. Valve assembly comes leak tested and assembled with 1 flow control orifice per bypass valve.
