Heavy Duty Hydraulic Actuators

Newly designed QTH Scotch Yoke Series incorporates several new design features to provide higher efficiency and cost effective solution.
 
These actuators show compact 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 QTH Series for all modulating as well as heavy-duty services virtually fitting any quarter turn (90 deg) application. 

PRODUCT SPECIFICATIONS
 
 
ACTUATORS QTH SERIES
 
Double-acting QTH 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 QTH Series actuators produce spring ending torque ranging from 1,350 Nm (11,950 lb-in) to 60,750 Nm (537,650 lb-in)Further torque ranges available on request.
 
 
The hydraulic operating pressure for the QTH Series ranges between 20 barg (290 psig) to 350 barg (5,000 psig).
 
Standart design construction allows operating temperature from -30 degC (-22 degF) to +93 degC (+199 degF).
 
Low temperature design extends operating range down to -60 degC (-76 degF).
 
Supply Medium:
Hydraulic oil mineral based (standard). Special versions are available for fire-resistant or water based fluids.
 
 
CONTROLS SYSTEM
 
Actuator Control Systems are integral part of any automated valve package. Our QTH Series actuators can be equipped with extensive range of auxiliary components specifically engineered and integrated to meet the largest variety of Customers' requests either for ON/OFF or modulating. Our Control System can be housed within cabinet &/or stainless steel (AISI316) panel folded over to provide sun-shade, and assembled on actuator or at remote location.
 
We have already pre-engineered different solutions to meet the most commonly required control systems. These solutions, based on standard components, offer reduced lead time, simplified purchasing,  commissioning and start-up activities. Please contact with us for any additional detail.
 
Position Monitor Device:
Virtually all positioning monitor devices can be assembled on top of our QTH Series actuators, responding to any kind of technical requirement.
