Actuator Type 2 - Technical Data, Summary
2Pages

WireMatic actuators are pneumatic quarter turn actuators based on double rack and pinion design. The Type 2 actuator is generally recommended to “large” Butterfly valves. Material, standard (outside) • Anodized Aluminum, Black • CNI, Chemically Nickel/PTFE Impregnated for increased corrosion resistance • Other treatments upon request Movement • 0° to 90° End Stop Adjustment Double End Stop Adjustments, Open and Closed position, located outside the pressurized zone at the BAK (Body Adaptor Kit) Over travel • Open: 3° • Closed, size 8 and 12: 2° • Closed, size 20 to 150: 3° Sizes • 35, 55, 70, 100 and 150 Torque Linear torque, ie a Double Acting (DA) Actuator has the same torque over the entire movement Torque Output, Double Acting (DA) at 6 bar/80 psi • 374 to 1655 Nm • 3055 to 13425 in.lbs Torque Output, Spring Return (SR) at 6 bar/80 psi • 133 to 586 Nm Operating Pressure • DA: 2-10 bar / 30-145 psi • SR: 2-10 bar / 30-145 psi. When the Actuators will be used at Operating pressures below 5.5 bar / 79.8 psi, we recommend that you contact your WM distributor.
