BI-TORQ® Rack and Pinion Pneumatic Actuator – Stainless Steel

BI-TORQ® Rack and Pinion Pneumatic Actuator - Stainless Steel/BI Series

BI-TORQ® BI Series Actuators feature corrosion-resistant 304 stainless steel housing that is ideal for environments where sanitary requirements are necessary and damp conditions occur. The series has an anti-blowout system that prevents damage from over pressurization. Durable, precision cast pistons provide full engagement with the pinion. The one-piece alloy shaft has machine gear teeth for precision operations. Heavy-duty spring cartridges allow for easy conversion of a double acting actuator to a spring return actuator, or to modify the torque output depending on air pressure.

A slotted shaft, along with the Namur bolt pattern, allows for direct mounting of Namur standard switches and positioners. The standard air supply pressure is 80 psi with a maximum pressure rating of 120 psi / 8 BAR. It has a star pinion output design for greater flexibility in actuator to valve mounting. It features an ISO 5211 bottom mounting for direct mount actuation with true ISO valves and ISO and NAMUR standards for top mounting for adding limit switches and positioners. Actuator types in either Double Acting (DA) and Spring Return (SR) options. Temperature ratings: Standard: -4°F-180°F | Max/Min: -40°F-302°F.
