What is the Haitima Spring Return Pneumatic Actuator Used For?
The Haitima Spring Return Pneumatic Actuator, also known as a Single Acting Actuator, is designed for automating the operation of ball, butterfly, and plug valves. It uses a spring mechanism to return the actuator to its default position upon loss of air supply, making it ideal for applications requiring fail-safe operation.
Key Features
0-90° Rotation Angle: The actuator provides a 0-90° rotation angle, perfect for piloting ball, butterfly, and plug valves, ensuring versatile application across various valve types.
Hard Anodized Aluminium Body: Constructed from hard anodized aluminium, the actuator body is protected against wear and corrosion, ensuring long-lasting durability and reliable performance.
ATEX II 2GD c T5 Certification: The actuator is ATEX II 2GD c T5 certified, making it suitable for use in potentially explosive atmospheres, adhering to strict safety standards.
Conforms to International Standards: The actuator conforms to ISO 5211, DIN 3337, and VDI/VDE 3845 standards, ensuring compatibility with a wide range of valves and accessories.
Epoxy Coated End Caps: The die-cast aluminium end caps are epoxy coated for maximum resistance against corrosive elements, enhancing the actuator's longevity.
NAMUR Pneumatic Connection: Designed with a NAMUR pneumatic connection, the actuator facilitates easy installation of solenoid valves, simplifying the automation process.
Wide Operating Temperature Range: The actuator operates effectively within a temperature range of -20°C to +90°C, making it suitable for various environmental conditions.
Maximum Working Pressure: Capable of handling a maximum working pressure of 8 bar, the actuator is robust and reliable under high-pressure conditions.
Twin Piston Rack and Pinion Design: The actuator features a twin piston rack and pinion design, providing a constant torque output and ensuring smooth, reliable operation.
Factory Lubricated: All moving parts are factory lubricated for the entire lifecycle of the actuator, ensuring maintenance-free operation.
Travel Adjustment: Standard travel adjustment of ±5° in both open and closed positions is easily accessible via external adjustment bolts, providing precise control.
High Performance Springs: Equipped with high tensile steel springs coated with zinc phosphate for corrosion resistance, the actuator offers long-lasting performance and reliability.
Durable Bearings and Guides: The actuator features highly durable bearings and guides made from a compound material, providing high thrust stability with minimal friction for extended life.
NBR O-Rings: Standard NBR O-rings ensure trouble-free operation at standard temperature ranges, with Viton and Silicone O-rings available for high or low temperature applications.
