QTRCO Linear Spring Return Actuators

QTRCO Linear spring return actuators operate with pressures from 40 to 120 psig. Springs cause the push rod to retract, thereby imparting a motion similar to that found on spring and diapragm linear actuators.
Standard Version	Shown with Smart positioner - Excellent for throttling services Click image to enlarge Click HERE for literature Click HERE for Sectioned Image	Jackscrew Version
Output forces are a function of the springs employed and the supply pressure. For very low supply pressures, multiple tandem pistons may be used to increase the force output and to enable use of high output springs.
Advantages Reduced cost Optional Stainless Steel materials of construction Corrosion resistant composite cylinders Smaller and lighter (by over 50%) as compared to spring and diaphragm types Excellent throttling control with analog or digital positioners Mounting patterns and push rod dimensions to suit application requirements
