The DVG Automation “QT” Scotch Yoke Series incorporates several new design features to provide higher efficiency and cost effective solutions. These actuators are compact in design but above all introduce a new generation of patented mechanism which minimizes wearing effect on all loaded & sliding parts, thus extending overall lifespan.
These features boost our QT Series for all modulating as well as heavy-duty services suitable for any quarter turn (90 deg) application.
The DVG Automation Double-acting QT Series Actuators are available with individual test and guaranteed minimum output torque ranging from 1,800 Nm (15,900 lb-in) to 180,000 Nm (1,593,000 lb-in).
Our Single Acting QT series Actuators deliver a spring ending torque ranging from 1,350 Nm (11,950 I n) to 75,700 Nm (670,000 lb-in).
Higher output torques are available on request.
The Hydraulic operating pressure for the QT Seri- es ranges between 20 barg (290 psig) to 350 barg (5.000 psig).
Standard design construction allows operafing temperature from -30 degC (-22 degF) to +93 degC (+199 degF).
Low temperature opfion extends operating ran- ge down to -60 degC (-76 degF).
Hydraulic oil mineral based (standard). Special versions are available for fire-resistant or water based fluids.
