Drive Heads

Banjo Head There are two models of Banjo Head which are ideal for valves with a rising stem. Standard Duty: BJH01 – Essential for all rising stem handwheels, the Standard duty banjo drive head caters for all stems up to a maximum diameter of 63mm (2.48’’). It can also operate all clamping systems for handwheel and other interfaces. In addition, it brings further reduction which means you can multiply the actuator’s torque by 4 and reduce the speed by the same factor. Perfect for difficult or stiff handwheels. With a maximum torque of 600 Nm (440 lb.ft), the Standard Duty Banjo Head can be mounted quickly and easily on all Easy Duty Actuators and on some Standard Duty Actuators. Heavy Duty: BJH02 – The Heavy Duty Banjo Drive Head should be used for very high torques. It caters for rising stems up to a maximum diameter of 70mm (2.75’’) and is compatible with all clamping systems for handwheel and other interfaces. It brings additional reduction which means you can multiply the actuator’s torque by 3 and reduce the speed by the same factor. With a maximum torque of 1000 Nm (740 lb.ft), the Heavy Duty Banjo Head can be mounted quickly and easily on all Easy Duty and Standard Duty Actuators. |

Wheel Drive Plates
All these factors must be considered when choosing your valve wheel drive plate.
| Self Aligning Wheel Drive Plate
This drive plate has spring-loaded wheel spoke fingers. As the wheel plate starts to rotate, the drive fingers cause the plate to centralise on the wheel axis. This ensures fully concentric rotation which minimizes operator fatigue. |
 |
| Standard Universal Drive Plate
This drive plate incorporates fixed wheel fingers for engaging on the valve wheel. The fingers are a low cost solution, fingers can be added or removed according to the number of wheel spokes allowing for greater customisation and ensures a good fit. |
 |
| FSB Drive Plate
This drive plate (adaptor) clamps solidly and quickly to the handwheel and can turn in both directions, with or without a rising stem. It is available in two versions – one that adapts to flat or slightly tapered (< 30°) handwheels and a second for tapered handwheels (> 30°). The adaptor has a strong hold on the handwheel and fixes firmly to the actuator, providing complete safety during manoeuvres, even in difficult positions. These versatile adaptors save a significant amount of time and money as there’s no need to buy and install a drive plate for each handwheel. |
 |
| CSB Drive Plate
These adaptors should be used for tapered handwheels with spokes at an angle greater than 30° in relation to the wheel’s plane. A choice of three models are available according to the number of spokes in the handwheel you want to turn. These adaptors can be used with a straight or right angle actuator due to the KTA002, and with a banjo head in conjunction with the TTA002 interface. These adaptors save a significant amount of time and money as there’s no need to buy and install a drive plate for each handwheel. |
 |
| FUA Fixed Universal Drive Plate
These adaptors must be fixed to the handwheel before use. Thanks to their multiple “U” clamps clamp on the handwheel’s spokes, they can fix on to almost every type of handwheel. The FUA adaptor is available in 4 versions for flat or tapered handwheels: FUA001(or FUA316 for stainless steel version) for flat or slightly tapered handwheels with spokes inclined up to 30 ° in relation to the wheel’s plane; FUA002 (or FUA317 for stainless steel version) for tapered handwheels with spokes inclined from 30° to 40° in relation to the wheel’s plane. These drive plate adaptors can be used directly on a banjo head. To use them with a straight or right angle head, you need to use the KPA004 interface. They can also be used with EBx04 extension bars. |

Extensions Shafts
Drive Adaptors
We stock a range of standard sizes for the more common shaft types, for example 20mm, 30mm and 40mm keywayed shafts. We also keep standard sizes for valve false tops with tapered squares.
Whatever shape or size is your drive shaft, we can design and manufacture an adaptor to suit. These images below show examples of bespoke adaptors made for more complex valve shafts.
Torque Management Devices
Every portable valve actuator is has a torque management device (arm) included in the standard kit. One end fixes to the collar of the portable actuator just beside the output shaft. The other end can be connected to a fixed structure close by to to the valve by means of a lanyard and carabiner.
Here are some images of different types of torque management devices. If you’re unsure about the most suitable torque management system for your needs, contact Valtorx.

Interlocks
Trapped Key Interlocks control safety-critical procedures using mechanical locking devices and keys. Interlocks from Valtorx have a wide range of applications and lock types to cover access doors, valves, power switches and more. Interlock systems ensure workers complete operations in a set sequence reducing the risk of accidental or unauthorised operation of equipment or processes.
