Rack and pinion actuator diagram.

The ut series rack pinion actuators are the original max air innovation featuring a removable flange for easy valve integration flexible customization and reliable operation. Rack and pinion combinations are often used as part of a simple linear actuator where the rotation of a shaft powered by hand or by a motor is converted to linear motion. The actuator is mounted as follows. In a pneumatic rack and pinion actuator the linear force of a piston driven by compressed air is converted to rotational torque via a rack and pinion gear mechanism.

Spring return and double acting versions shown. We also cover the operating conditions and mounting standards that our expert rack and pinion actuator manufacturers recommend. Install the correct adaptor if required into. Rack and pinion actuator below you ll learn about the various components of tiger valve state of the art rack and pinion actuators.

The ut series has been replaced by the mt series above except for when alternative mounting is required. Ensure that the valve and actuator are both in the following positions. See how rack n pinion pneumatic valve actuators work. Double acting units fully closed single acting units air fail mode normally closed 2.

Single and double rack and pinion actuators include a grease fitting to help provide easy maintenance. This torque based standard has become the industry standard and many valves are available that allow direct mounting eliminating cost for bracket and coupling. Best live chat. A rack and pinion as shown in figure 2 consists of a circular gear the pinion engaged in a linear gear the rack.

Rack and pinion actuators often offer the most economical solution for quarter turn valves that have a fairly constant torque requirement throughout the stroke. Rack and pinion actuators have standardized interface flanges interfaces for valves solenoids and control accessories. Order online or call toll free 1 800 899 0553. The rack carries the full load of the actuator directly and so the driving pinion is usually small so that the gear ratio reduces the torque required.

This force thus torque may still be substantial and so it is common. Rh rack and pinion hydraulic actuators are engineered to operate ball butterfly plug and other quarter turn valves for either on off or modulating service. Valve interfaces generally comply to the iso 5211 standard. Spring return and double acting versions shown.
