Quad4 Pneumatic Actuators High Performance, Four Piston, Rack & Pinion Actuators

Transcription

1 The SVF Quad TM quarterturn rack & pinion actuator is a four piston actuator which generates torque around a centrally located pinion, giving more than double the torque of single & double rack & pinion actuator designs. The increased number of pistons allows their diameter to be reduced while maintaining it s high torque, allowing the reduced size of the actuator.

These stops allow for true +/5 o for valve travel adjustment to ensure precise positioning in all flow control services. The Quad travel stops are designed to absorb the maximum rated torque of the actuator and the maximum impact loads associated with the recommended stroke speed.

5 QUAD ACTUATOR SIZING GUIDE Selecting the correct Actuator (Sizing) The output torques for each actuator model are listed in the Torque Tables (Pages and ). These values do not include a safety factor. For best results we recommend selecting an actuator model with a minimum output torque that is greater than the highest operating torque of the valve to be actuated, plus 10%. Example for Double Acting (QD) Actuator Sizing: Published Valve Torque: Air Supply: Quad Model: 0 inlbs (plus 10% safety factor = inlbf) psig QD5 The QD5 has the output torque value of 69 psig. Example for Spring Return (QS) Actuator Sizing: Published Valve Torque: Air Supply: Quad Model: 0 inlbs (plus 10% safety factor = inlbf) psig QSC The QS (C Spring Set) has the following output torque psig: Air End: 5 inlbf Spring End: 89 inlbf Sizing Safety Factors Media and other conditions can effect the operating torque of a valve. Following is a list of common Safety Factors.
