GCQ series pneumatic vacuum plug valveDetailed product description：

GCQ vacuum plug valve is a valve used to open or block airflow in a vacuum system with a pressure range of 1.3 × 10-7~105Pa.

Main performance
Leakage rate: 1.3 × 10-10Pa.M3/S;
Pressure range: 1.3 × 10-7Pa~105Pa;
Medium: Air;
Working temperature: -30 ℃ to+150 ℃;
Installation location: arbitrary;
Switch signals: electrical signals, mechanical signals;
Opening and closing time: ≤ 3 seconds;
The pressure difference between the opening and closing sides of the valve plate is 1000Pa to 2000Pa.
Gas source pressure: 0.4-0.6kg/cm2

Principle
Powered by compressed air, the cylinder piston rod pushes the steel ball holder to move, opens the valve plate and closes it, and then retracts the vacuum valve after the valve plate is opened by spring force.
