真空挡板阀

真空挡板阀是以电磁力为动力直接带动阀板动作，达到阀门开启或关闭的目的。在真空系统中用来切断或导通气流。适用介质为纯净空气或非腐蚀性气体。

Reliable, economical, general-purpose components for HV and UHVapplications requiring cleanliness and corrosion resistance.

In the open position

Edge-welded bellows and valve seat move out of the gas path therebyachieving high conductance

Can withstand intermittent baking to 200° C (150° C Continuous),improving ultimate vacuum

Features

Leak rate across seat: 2×10-9 mbar L/s

Pressure Max: Atmospheric pressure

Pressure Min: 1×10-9 Torr

Feature fluorocarbon o-ring seat seals, bellows-sealed shafts, andbonnet seals (select copper for higher temperature bakeout and better ultimatevacuum)

Available in manual or pneumatic actuation

Normal repairs can be made without removing the valve body from thesystem

NOTE: We list a wide variety of standard tube sizes from 3/8″to 4″. Other sizes and valves with mixed flanges are available on request.

NOTE: Pneumatic valves require a solenoid operator (soldseparately). Please see the Angle Valve Accessories chart for thesizes/voltages that are available.
