Product Description

High Vacuum Needle Metering Valve

High vacuum metering valves are used to control gas flows. Precise flow rate is set by adjusting the dial. Great for controlling the exact flow rate into or out of the system for: 1. adjusting the vacuum level. 2. adjusting vacuum flow speed. 3. back filling with inert gas. 4. safe and gradual release of vacuum. 5. stabilizing vacuum controlling system

Techical Data:

1.Pressure range:1x10^(-5)Pa~1.2x10^(5)Pa 2.Service life until first maintenance:3000 times 3.Minimum adjustable flow:4.7x10^(-3)Pa.L/S 4.Valve body baking temperature:≤150℃ 5.Pressure difference on opening:≤1.2x10^(5)Pa Any 6.Installation orientation: Any 7.Body and seat leak rate:1.3x10^(-7)Pa.L/S 8.Valve position indication:With dial indication
