Pneumatic Actuator
Automatic control of silo valves and discharge equipment is an important criterion in modern concrete and material handling plants. The pneumatic actuator provides the force and motion needed to open or close valves (such as butterfly valves or slide gates) reliably and repeatedly, facilitating automation and remote control in bulk material systems.
WorkIng PrIncIple
A pneumatic actuator uses compressed air to generate linear or rotary motion. When air is applied to the piston/chamber, the actuator moves the valve shaft, providing controlled motion. Spring-return or double-acting configurations are available. The actuator detects end positions via limit switches or sensors and integrates easily into automated control systems.
Advantages & Features
* Fast and repeatable operation (milliseconds).
* Suitable for harsh environments (dust, heat, vibration).
* Compatible with pneumatic control systems common in batching plants.
* Multiple mounting options and sizes to match valves from DN80 to DN300+.
* Low maintenance due to simple mechanical design and air-based actuation.
