Our GIQ series pneumatic high vacuum butterfly valve is a specialized flow control device engineered exclusively for opening, closing, and regulating vacuum airflow in industrial vacuum systems. Designed for use with air and non-corrosive gases, this valve delivers reliable, high-speed on/off control with exceptional flow conductivity, making it the ideal choice for automated vacuum process management.
The working principle of this pneumatic vacuum butterfly valve relies on a precision-engineered disc closure member, rotated 0-90 degrees via the valve stem to open or close the flow path. The valve is driven by compressed air, with an integrated electromagnetic device that redirects airflow to control the rotation of the pneumatic actuator, which in turn drives the valve disc to the fully open or fully closed position. The actuator is available in double acting or single-acting spring return configurations, and can be paired with an intelligent positioner to accept external control signals for precise modulating control of vacuum airflow. Optional solenoid valves and position indicators can be added to enable fully automated remote operation and real-time status monitoring.
The integrated pneumatic actuator delivers fast, repeatable opening and closing cycles, with flexible configuration options to match your process needs. Double acting actuators provide consistent torque for high-cycle applications, while single-acting spring return actuators ensure fail-safe operation in the event of air supply loss. Optional intelligent positioners enable precise modulating control, adapting to variable vacuum process requirements.
With a maximum leakage rate of ≤1.3 ×10⁻⁵ Pa·L/S, this high vacuum pneumatic butterfly valve delivers bubble-tight shutoff that meets the strict performance requirements of high vacuum systems, preventing air ingress and maintaining consistent vacuum levels for critical processes.
The valve body, disc, and stem are available in both carbon steel and stainless steel, with seal material options including NBR and Viton to match your temperature and media compatibility needs. The robust construction ensures long service life even in continuous industrial operation, with minimal maintenance requirements.
The valve supports installation in any orientation, with a compact footprint that fits seamlessly into space-constrained vacuum piping layouts. A wide range of optional accessories enables full customization to integrate with your existing process control systems, with no need for extensive modifications.
This pneumatic high vacuum butterfly valve for non-corrosive gas is widely used in industrial vacuum systems across sectors including vacuum furnace manufacturing, vacuum coating equipment, electronic component production, environmental protection gas treatment systems, industrial air handling, chemical gas processing, packaging machinery, and general industrial vacuum pipeline systems. It is the preferred choice for applications requiring automated, reliable control of vacuum airflow, such as batch vacuum processing, vacuum drying systems, and closed-loop gas recovery systems.
