Torque Control Pneumatic Actuators are available in both Double & Single Acting Models with an output torque ranging from 30 Nm to 4000 Nm at 6 Bar (600 kPa) operating pressure. They are suitable for a maximum operating pressure of 10 Bar (1000 kPa) operation.
Torque Control Pneumatic Actuators feature 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.
Electric Actuators
Torque Control Electric Actuators (TCEL Series) are available from 100Nm to 3000Nm torque output. Due to robust design and construction, they can be used in most industrial enviroments. The housing is hard anodised Aluminium Alloy and external epoxy coating paint provides superior resistance for rigorous enviroments.
Our Electric Actuators are fitted with a specially designed squirrel cage induction motor to generate high starting torque and is fitted with thermal overload protection to prevent damage from overheating. Included internally are both torque and limit switches for remote indication. Our TCEL Series also feature a highly visible dome position indicator.
Our Electric Actuators are supplied standard with manual override and external operating clutch lever that switches the Actuator to manual mode. This is automatically disengaged when switched to electrical operation. The gear mechanism is self locking to eliminate the possibility of reverse movement from the valve. Our design features ISO mountings and removable drive bushing that allows easy adaption to suit most valve requirements.
Available with a range of optional accessories including extra limit switches, potentiometer, process control unit, local control and signal indication.
Hydraulic Actuators
Torque Control carry DAMCOS Hydraulic Actuators in both Double Acting (Model BRC125-BRC16000) and Single Acting (Model BRCF125-BRCF16000) with an output torque ranging from 125Nm to 16,000Nm at 135 Bar operating pressure. All Actuators have a working temperature range of -20C to +80C and the burst test at 675 Bar.
DAMCOS Hydraulic Actuators have a very compact design and delivers high output torque. This design is very good for applications with space or weight constraint. DAMCOS Actuators come with hydraulic/electrical position indicators, customized control units and system power unit. DAMCOS uses blank bushing and mounting plate which allows any quarter turn or linear valve to be easily mounted. DAMCOS patented multi-helical spline design uses minimum oil volume and compact dimensions.

Manual Override Gearboxes
Torque Control Manual Override Declutchable Gearboxes (TCMO 030-3200) ranging from 300Nm to 32000Nm offer reliable and simple manual positioning of valves, and other quarter-turn devices where manual override is required on pneumatic or hydraulic rotary actuators.
All our TCMO series are of rugged design, light weight and modular to provide the most efficient and cost effective solution for a comprehensive range of manual override options. Our Gearboxes are external epoxy painted which provides superior resistance for rigorous enviroments. The self-locking worm gear is designed to provide safe and easy operation and long life.
Limit Switch Boxes
Torque Control Limit Switch Boxes are available in both Composite, Aluminium & SS316 Stainless Steel Housings. Available in IP67 and Explosion Proof Enclosures with both IEC Ex and ATEX Certification.
All come with High Visibility position indicators Black/Yellow (standard) or Red/Green to provide clear local indication of the valve position. Easy adjustment of the switches is possible by the use of a twist cam design with colour coded sensors.
Switchboxes can be fitted with a comprehensive range of switches including Mechanical, Magnetic Reed, Inductive Proximity, PNP, ASI Bus & Profibus DP. Usually supplied with two switches, we can fit 3 or 4 additional switches as required for mid travel feedback.
We have in stock or can fit a range optional switches, these include P&F NC-B2 V3 (Intrinsically Safe), NBB2-V3-E2 & NBB3-V3-Z4 into either Composite or Aluminium & Stainless Steel Switchboxes.
All switchboxes come complete with mounting brackets to suit NAMUR VDI/VDE 3845 topworks footprint with adaptors to suit actuators with different mounting arrangements. All fasterners included in mounting kits are stainless steel to resist corrosion.
Positioners
Torque Control Positioners are available in both Rotary and Linear and come in Aluminium and SS316 Stainless Steel housing. Our positioners are available in IP66 or Explosion Proof enclosures and come with optional Dome Indicator. They are available in both Double Acting and Single Acting Type.
Torque Control Smart Positioners (Fail close/open) are available in Aluminium and SS316 Stainless Steel housing. Our smart positioners are available in IP66 or Explosion Proof enclosures and come with optional HART, PTM and Dome Indicator. They are available in both Double Acting and Single Acting Type.
Accessories
Torque Control have a wide rage of accessories to suit the needs of our customers. We design and fabricate Carbon Steel/Stainless Steel mounting brackets and bushings to suit our client's valve requirements. We also provide SS316 piping/fittings, SS316 Square Adapters, Silencers, Boosters and Filter Regulators.
