Product catalog summary
Overview
WireMatic TruTorq AB provides technical data for their Type 2 pneumatic quarter turn actuators, designed primarily for large Butterfly valves. These actuators utilize a double rack and pinion design.
Material and Construction
The standard exterior material is anodized aluminum, with options for chemically nickel/PTFE impregnated finishes for enhanced corrosion resistance. Other treatments are available upon request.
Movement and Adjustments
The actuators offer a movement range from 0° to 90° with double end stop adjustments for open and closed positions, located outside the pressurized zone. Over travel is specified as 3° for open and varies for closed positions depending on size.
Sizes and Torque
Available sizes include 35, 55, 70, 100, and 150. The actuators provide linear torque, with double acting (DA) models offering 374 to 1655 Nm (3055 to 13425 in.lbs) and spring return (SR) models offering 133 to 586 Nm (1676 to 4758 in.lbs) at 6 bar/80 psi.
Operating Pressure
Both DA and SR models operate between 2-10 bar (30-145 psi). For pressures below 5.5 bar (79.8 psi), consultation with a distributor is recommended.
Drive Medium and Temperature Range
Standard drive mediums include air (dry or lubricated) or inert gases, with options for oxygen, hydraulic oil, or water requiring rebuilding. Temperature ranges vary by seal type, with standard execution from -30° to +80°C, high temperature from -20° to +140°C, low temperature from -45° to +60°C, and arctic temperature from -50° to +60°C.
Stroke and Configuration
For DA models, Port A is for air to open (anti-clockwise) and Port B for air to close (clockwise). SR models use Port A for air to open and Port B as an exhaust port, with a factory setting of fail close (clockwise closing).
Drive Shaft and Connections
The Body Adaptor Kit (BAK) features a standard square drive compliant with ISO 5211, with options for Double D or Key drive. Standard connections include solenoid valves (Namur) and fitting accessories (ISO 5211, DIN 3337, Namur).
Lubricants and Standards
Recommended lubricants include Statoil Molyway LI 712 for springs and piston rack segments, and Statoil Uniway LIX 42PA for O-rings and plastic parts. The actuators comply with various standards and hold multiple certificates.
