General Features:
The Trueline "2A" Series of valve actuators are designed to automate valve operation. These actuators can be adapted for many applications, including special needs. Their compact design allows for easy installation. The Trueline "2A" cylinders are fabricated under strict quality conditions.
Features:
• Head & Cap - numerically controlled machined from hot rolled steel plate ASTM A36 or better.
• Piston Packing - 2 pressure sensitive "U" cups for better sealing & durability.
• Piston Rod - high carbon content steel SEA 1045, ground, polished & chrome plated (chrome plated 316 Stainless Steel available on request).
• Rod Wiper - stops dust & other particles from entering into the cylinder. Standard material is polyurethane. It can be replaced by flurocarbon for higher temperature applications.
• Seals & Packing - "U" cup & "O" ring used for added security. A high durometer nitrile material is offered as a standard for a temperature rating from -34°C to 120°C (-30°F to 250°F). For temperature ranges up to 250° (450°F), flurocarbon (Viton) seals & packings are available.
• Gland Bushing - Cartridge type, made from Bronze SAE 660. Seals can be replaced without dismantling the cylinder.
• Tie Rods & Nuts (bore sizes from 3-1/4" to 12") - made from stainless steel to limit corrosion.
• Tie Rods & Nuts (bore sizes from 14" to 20") - high strength steel bar stock along with zinc plated steel nuts (grade 5).
• Cylinder Barrel (bore sizes from 3-1/4" to 12") - seamless heavy wall steel tubing with a polished chrome plated interior for better durability.
• Cylinder Barrel (bore sizes from 14" to 20") - Thermoset fiber reinforced composite, specially designed for cylinder tubing for weight reduction & corrosion resistance.
• Piston (bore sizes from 3-1/4" to 8") - numerically controlled machined from high strength aluminum bar stock (6061-T6).
• Piston (bore sizes from 10" to 20") - made from mild steel. A wear strip is added on the outside diameter to protect the tube & assure a perfect fit.
• Piston Wear Strip (bore sizes from 10" to 20") - it consists of a Teflon tape filled with particles of bronze & glass, for smoother piston operation.
Options Available:
• Stainless steel piston rod.
• Double ended cylinder.
• Viton seals (450°F).
• Piston rod scrapper.
• Water operation (AWWA).
• Spring return (fail safe).
• Manual over ride.
Pneumatic Cylinders are installed on our knife gate valves to automate the valve operation. We provide all sort of controls and customization on the cylinders.
