LP linear pneumatic piston actuators are designed to control airflow dampers and butterfly valves in boiler and air distribution systems, with cylinder sizes ranging from 63.5 mm diameter × 127 mm stroke to 254 mm diameter × 406.4 mm stroke. They are available with Buna-N or Viton seals, supporting temperature ranges from 4 to 85 °C and up to 121 °C respectively. Actuators can be paired with AV, TZIDC, or EDP300 positioners, supporting HART, FOUNDATION Fieldbus, and PROFIBUS PA communication, with explosion-proof variants available. Minimum supply pressure is 2.7 bar (40 psi); maximum is 6 bar for TZIDC and 10 bar for AV and EDP300. Thrust ratings vary by cylinder size, with examples up to 24,372 N (5479 lbf) at 5.5 bar (80 psi) air supply.
“Simple Cylinder” Type LP Linear pneumatic actuators are supplied with either type AV conventional or type TZIDC digital positioners mounted on the cylinder. Cylinders are supplied with a threaded clevis on the rod end. Base mounting pivots can be ordered as an accessory. A protective boot is optional.
