In this article, you will understand how pneumatic valves and cylinders used in bus doors work, their main technical characteristics, best maintenance practices, and the differentials that make RGR a strategic choice for manufacturers and operators in the sector.
Read on.
The importance of pneumatic systems in buses
Pneumatic systems enable the precise and safe actuation of valves and cylinders responsible for repeatedly opening and closing doors.
This technology is widely adopted in urban, intercity, and electric buses, as it offers a series of operational advantages.
Pneumatic systems present high durability, low maintenance, and excellent performance in environments with thermal variations and high demand for daily cycles.
However, for this performance to be maintained over time, it is essential that pneumatic components be designed according to bodybuilders’ requirements, meeting criteria for mechanical resistance, efficient sealing, and operational precision.
It is in this scenario that the quality of pneumatic cylinders and valves becomes crucial for the efficiency of the entire system.
RGR Pneumatic excellently meets these demands, providing robust, durable solutions compatible with the most diverse bus models available in the national market.
How pneumatic valves and cylinders for bus doors work
We already know that the pneumatic system for opening and closing doors in buses works through the combination of pneumatic cylinders and directionally controlled valves.
Together, these components ensure the fast, safe, and synchronized actuation of doors, meeting safety standards and the intense operational routine of public transport.
Pneumatic cylinders
Pneumatic cylinders are the actuators responsible for transforming compressed air energy into linear mechanical movement. In the case of buses, this movement promotes the pushing or pulling of rods that control the opening and closing of doors, according to the body design logic.
These cylinders need to be:
- Compact, to adapt to the available space in bodies;
- Resistant to vibration and weather conditions, common in urban and intercity use;
- Capable of operating thousands of cycles per day, with minimal wear.
RGR offers cylinders with high-quality seals, robust construction, and customized options, ideal for meeting different body configurations and manufacturers.
Pneumatic valves
Valves control the flow of compressed air into or out of the cylinders. They direct the air according to the system command (usually electronic or manual), allowing synchronized movement of the cylinder rod to open or close the door.
It is essential that these valves have:
- High reliability in switching (position change);
- Quick response to command;
- Efficient sealing, preventing air losses and ensuring energy savings.
RGR’s valve line is developed with a focus on vehicular applications, meeting the sector’s technical standards and ensuring full compatibility with pneumatic systems installed in urban, intercity, and electric buses.
