The LPV2 LoPro™ Two-Stage Vacuum Isolation Valves achieve a soft pumpdown and vacuum system isolation in one common housing. A small bypass valve is integrated into the main isolation valve, simplifying setup and reducing costs. With the integrated soft pumpdown feature, turbulent flow is diminished preventing contamination buildup and damage. The bypass valve is user adjustable by selecting a micrometer or thumb screw adjustment option. Additionally, a fixed flow orifice can be sized for the application that is housed internal to the valve to prevent unwanted adjustment. LoPro™ Valves are extremely reliable, with a lifetime that can extend to 1,000,000 cycles under clean conditions, greatly increasing system uptime. For an integrated two-stage solution please refer to our Integrated LoPro (ILP) products.
