In case of unusual downward movement of the pinion, the keyways will interphere with the grooves on the pinion and therefore stopping it. ± 10° Adjustment Travel Stop ISO 5211 Direct Valve Mounting Anodized Extruded Aluminum Body Lower and Upper Pinion...

High Cycle Life Design Precision Honed Bore Precision Honed Bore, High Cycle Wear Bearings, Unlimited Cycle Life Warranty, Rugged Tooth Design This high end feature, is not industry standard. A uniform bore surface provides consistent seal contact and compression. Micro-scratches provide even lubrication which minimizes the “wiping” effect. Our Honed Bore will provide consistent long-life operation with multiple seal materials and greases. High Cycle Wear Bearings Honing Surface Finish High performace technopolymer bearings eliminate metal-to-metal sliding contact. • Low friction , Large contact...

Torque Data Torques, Explaination of Sizing, Operation, & Spring Configuration Double Acting: Torques, Sizing, & Configuration Double Acting Torques Rack & Pinion actuator produces a costant torque output (Fig A) that depends on the internal diameter and the air supply pressure: increasing one or both factors, torque increases. Valve’s operation torque is not constant but presents a trend different depending on valve’s type. . Prior to sizing it’s necessary to obtain the following information and data: • Type of valve and rated torque • Air supply pressure The sizing is as follows: 1. Define...

MT Series Technical Brochure Max-Air Technology Inc. | Rotary Actuators & Valve Automation Solutions Spring Return: Torques, Sizing, & Configuration Spring Assembly Right Position The spring return actuator has a decreasing torque output throughout the stroke (Fig B). During the opening phase, the torque decreases, because the springs are compressed, and, working against the piston’s stroke, absorb energy. In the closing phase instead, the springs release this energy. So the torque is stated with 4 values: • Opening Start/Pos. 2 • Opening End/Pos. 2 • Close Start/Pos. 1 • Close End/Pos. 1 Spring...
