Details
Agilent’s family of vacuum Stainless Steel Tube Valves are designed to connect our rough vacuum and high vacuum pumps to your system. Delivering maximum conductance and sized for easy, convenient installation, these valves are ideally suited for systems requiring high reliability with low outgassing. Excellent low outgassing characteristics are derived from the valve’s fusion welded 304 stainless steel body, welded AM-350 stainless steel nesting bellows and small cross section elastomers and do not contain any blind internal cavities. In combination with our popular hardware products, the new stainless steel valves offer a complete, bundled solution for your vacuum system, making it possible for convenient one-stop shopping for everything required to connect Agilent vacuum pumps to your system.
