Surplus Bypass Vacuum Valves  
• Two (2) Stage  
• Bypass Valve Allows for Soft Start 
 HPS® Two-Stage valves are isolation valves that allow for slow pumping of a vacuum system. The bypass valve creates a small opening for the initial pump down, slowing system evacuation. This reduces contamination induced by particle turbulence and damage due to sudden pressure changes.
