Pneumatic Actuator

Pneumatic Actuator

AT Series Actuators which compact design, long life services, high quality, gear, and gear rack. This product is used for 90-degree rotational valves, such as ball valves, butterfly valves, plug valves, etc. BCST put the product quality as the first task, adopts the most advanced production and technology, stronger than the similar product on both product quality and performance. At series air operated actuator is the design is compact, the life is long, the quality is high, rack,s-like air operated actuator.

Design Features

Pneumatic actuator are integrated of new technologies, new materials, new innovative ideas based on the research, development, design, has the following characteristics:

• Comply with the standard of ISO5211, DIN3337, and VDE-3845, NAMUR standards.
• Extruded high-strength aluminum cylinder body, the inner surface of fine grinding and hard anodized, long service life, low friction coefficient, fast action.
• Beautiful compact, modern styling, multi-standard products make the selection more economical.
• All active surfaces are made of high-quality bearings, low friction, long life, no noise.
• Two independent stroke adjustment mechanisms for easy adjustment of±5deg and fully open or closed position.
• They are available in double-acting and single-acting(spring return), single-acting with normally closed and normally open.
• The NAMUR standard multi-function position indicator visualizes and outputs all accessories.
• Pre-compression load spring, installation, demolition of safe and convenient.
• Piston and end caps using die-cast aluminum alloy, high strength, lightweight.
• Change the seal material can be used in high-temperature or low-temperature applications.
• Solenoid valve can be installed without a connection plate.

Materials

• Indicator: NAMUR standard indicator for easy installation of position switches, locators and other accessories.

Output Shaft: Nickel-plated steel, high-precision integrated output shaft at the same time meet NAMUR,ISO5211, DIN3337 standards. Can be customized according to customer size and stainless steel materials.

Cylinder Body: ATMS6005 extruded aluminum alloy cylinder body can be hard oxidation, oxidation, epoxy spray paint(blue, orange, yellow sprayed on request),PTFE coating or nickel to meet different requirements.

End Cap: Die-cast aluminum alloy metal powder coating of various colors, PTFE coating or nickel plating.

Piston: Double-piston rack, with die-cast aluminum oxide or cast steel galvanized ,the installation position symmetrical, rapid operation, long service life, simply reverse the piston can change direction.

Stroke Adjustment: Two independent stoke adjustment screw can be convenient, accurate ±5°regulation on, off position.

High-performance spring: Imported high-quality materials, coating pre-treatment combined type assembly, demolition simple and safe. Using high quality materials, coating treatment, pre-press assembly. Has strong corrosion resistance and service life. It is safe and easy to disassemble the single-acting actuator and change the of springs to satisfy different torque output range.

Bearings guide: Low friction, long life composition materials, to avoid direct with metal and metal, maintenance and replacement is simple and convenient.

Sealing: At room temperature working conditions using NBR, in high temperature or low temperature with viton or silicone rubber.
