# GUQ Series Pneumatic Vacuum Sphere
## Product Introduction
The GUQ series pneumatic vacuum sphere is an efficient valve designed for the control of medium flow in vacuum systems. Powered by compressed air, this valve is adept at connecting or severing flow paths with precision.
### Operation Principle
This valve operates by utilizing compressed air to manipulate the pneumatic actuator, which in turn redirects the gas flow. The movement of the plug rack and gear is facilitated by the mechanical transmission, driven by the angular stroke's output torque, resulting in the balls' opening and closing motion.
## Features
- Available in double-acting and single-acting (spring return) configurations.
- Optional feedback signal device and electrical valve positioner for enhanced control.
- Compatible with gas or liquid media, including those with acidic or alkaline properties.
## Vacuum Ball Valve Highlights
The vacuum ball valve is a 90° rotary ball valve known for its superior sealing performance and large flow capacity. With a minimal flow resistance coefficient, this valve boasts a simple structure, ease of maintenance, and a long service life.
### Benefits
- The valve body channel matches the connecting pipe diameter, ensuring minimal flow loss.
- Widely used in applications with stringent sealing requirements, suitable for gases, liquids, steam, and even sewage with fibrous impurities.
- Common in industries such as petroleum, chemical, metallurgy, light industry, paper mills, power stations, and refrigeration.
### Industry Relevance
As a crucial valve type, the vacuum ball valve is extensively used in the petrochemical industry and for long-distance pipelines. Its closing mechanism features a perforated ball that rotates with the valve stem, enabling the valve to open or close fully with a 90° rotation.
### Advantages Over Traditional Valves
Compared to gate and globe valves of similar specifications, the ball valve is compact and lightweight, making it easier to install in pipelines.
