Preload Ballast System
QTRCO Rack & Gear® Actuators
have extremely low internal friction, consume minimal air volume, are able to handle the most severe vibration and are available in stainless steel for complete protection against corrosion. Rack & Gear® actuators provide throttling capabilities consistent with those of diaphragm actuators with a high level of reliability.
The QTRCO Rack & Gear® thru-shaft design results in substantial space savings. These actuators have been proven to be excellent companions to quarter turn control valves including those with extended stems.
