Pneumatic Cylinder Actuator for Diverting Gates

Product Specifications

Technical details and manufacturing context for Actuator (Pneumatic Cylinder)

Definition

This pneumatic cylinder actuator is a component used in diverting gate systems within industrial material handling and processing lines. It converts the potential energy of compressed air into linear mechanical motion, which is then used to position a diverting gate. The actuator consists of a cylinder barrel, piston, piston rod, end caps, and seals. When compressed air is supplied to one side of the piston, a pressure differential is created, causing the piston to move along the cylinder bore. This linear motion is transmitted through the piston rod to the gate mechanism, enabling precise control over the gate's position to direct material flow. Directional control is managed by pneumatic valves that regulate the flow of air into and out of the cylinder chambers. The actuator is available in various configurations, with bore sizes ranging from 32 to 200 mm and stroke lengths from 25 to 500 mm, as per ISO 6432. Operating pressure ranges from 0.4 to 1.0 MPa, and the recommended operating temperature is -20 to 80°C. Piston speed can vary from 50 to 500 mm/s, and cushioning is adjustable to prevent end-of-stroke impact. Port sizes are G1/8 to G1/2 per ISO 228-1. Standard seal material is NBR, with FKM available for high-temperature applications. The cylinder tube is typically aluminum, with stainless steel as an option, and the piston rod is made of hard chrome-plated 45# steel. The actuator's weight ranges from 1.5 to 35 kg, depending on bore and stroke. It has an IP65 rating per IEC 60529, indicating dust-tight and water-jet protection. These specifications are reference ranges; actual values must be confirmed with the manufacturer for the specific model and application. The actuator is designed for use in industrial environments and requires proper selection of bore size, stroke, and other parameters to match the gate's force and travel requirements. Regular maintenance includes checking seals and lubrication, and monitoring for leaks or unusual noise. Failure to operate within specified parameters may lead to reduced performance or damage.

Working Principle

Compressed air is supplied to one side of the piston, creating a pressure differential that moves the piston along the cylinder bore. The linear motion is transferred through the piston rod to the diverting gate, positioning it to direct material flow. Directional control valves regulate the air flow, allowing the gate to move forward or backward. Cushioning at the end of the stroke absorbs impact, and the speed is controlled by adjusting air flow.
