Torque Control Pneumatic Actuators are available in both Double & Single Acting Models with an output
torque from 30 Nm to 4000 Nm at 6 Bar (1600 kPa) operating pressure. They are suitable for a maximum
operating pressure of 10 Bar (1000 kPa) operation.
Scotch Yoke Actuators are designed to provide higher seating and unseating torques to suit break, run and
reseating torques of Ball, Butterfly & Plug Valves.
The Torque Control Pneumatic Actuator features a modern scotch yoke mechanism with high starting
and ending torques in a compact package. Due to the design this translates to higher break and reseating
torques with substantially lower air consumption. Closing position adjustment is possible on all Double Acting
Actuators.
Actuators are fitted with low friction wear pads to eliminate contact between the piston and the body which
guarantee long life and lubrication free operation throughout the Actuator range. The Actuator housing is
hard anodized internally and externally to provide superior protection from most environments.
Single Acting Actuator Springs are powder coated, pre-tensioned and retained in a spring module for long and
trouble free operation, ensuring complete safety during assembly or disassembly and general maintenance.
The standard Spring module is designed for 5.5 (550 kPa) to 6.0 (600 kPa) Bar operation. Different spring
modules are available to suit other operating pressures.
Torque Control Actuators have a universal ISO Mounting Pad that allows easy mounting to most rotary
valves. The top works is NAMUR to facilitate easy mounting of switches, positioners and accessories.
