Product Description
The AT series pneumatic valve actuator features a compact design, long service life, and high-quality construction. It is equipped with a rack and pinion mechanism, making it ideal for 90° rotating valves such as ball valves, butterfly valves, and plug valves. At BTRCV, we prioritize product quality and continuously adopt advanced production technologies to ensure our products outperform similar ones in both quality and performance. The AT series air operated actuator is known for its compactness, durability, and high output power. **Key Features:** - Dual Position Rack - Integrated Design - High Output Power - Long Service Life - Stainless Steel Fasteners for Corrosion Resistance - Low Friction Material at the Interface Between Piston, Pinion, and Body **Specifications:** - **Pressure Range:** Max. Working Pressure: 10 bar (145 psi) - **Air Pressure:** 2.5 bar ~ 8 bar (36 psi ~ 116 psi) - **Rotation Angle:** 90° ± 5° - **Ambient Temperature:** - Standard: -20°C (-4°F) to +80°C (+176°F) - High-Temperature: -15°C (+5°F) to +150°C (302°F) - Low-Temperature: -40°C (-40°F) to +80°C (+176°F) - **Acting Type:** Single-acting (spring return), Double-acting - **Optional Accessories:** Solenoid valves, limit switches, electric positioners - **Lubrication:** All moving parts are coated with lubricants for extended service life - **Life Time:** Over 1 million cycles **Standards Compliance:** - **Interface with Valve:** 4 or 8 bolt orifices according to DIN/ISO 5211; axle assemble orifice according to DIN 3337 - **Interface with Control Valve:** 7100 D/S–7350 D/S according to NAMUR or VDI/VDE 3845; 7040 D/S–7090 D/S via adapter plate - **Interface with Signal Box:** According to VDI/VDE 3845 **Product Structure:** - **Actuator Body:** Made of extruded aluminum alloy, machined on precision centers. Both internal and external surfaces are hard anodized for low friction and longer life. - **End Cap:** Cast from high-pressure aluminum, coated with anti-corrosive thermoplastic. All single-acting and double-acting actuators share a similar body and cap, with the acting mode changed by adding or removing the spring. - **Drive Shaft:** Made of medium carbon steel with fine processing and nickel plating for better corrosion and friction resistance. - **Piston:** Die-cast aluminum alloy, capable of delivering maximum torque under operating pressure. - **Piston Seal:** NBR-70 rubber seal ensures reliable performance under normal temperature. FPM seals available upon request. - **Travel Adjustment:** ±5° travel can be adjusted using two bolts. This actuator is widely used in industrial automation systems where precise control and long-term reliability are essential. Its robust design and versatile application make it a preferred choice in various industries including oil and gas, chemical, and power generation.
