IMPACT™
Applications
The IMPACT™ can be utilized directly on site where operating conditions may occur that
cause functional disorders or become a safety issue. Some typical examples are given here:
1. Actuators that are not achieving their published torque output can have the IMPACT™
field mounted to improve their reliability without having to replace them or stop the process.
2. In situations where unexpected pressure drops occur, such as at beginning of a days work
or when additional accessories are added to a system, the IMPACT™ will keep the pressure
level at its maximum and prevent the actuators from shifting from their position.
3. In many cases it is possible to substitute a smaller actuator with the IMPACT™ and achieve
the torque output of a larger actuator.
4. The IMPACT™ will increase the reliability and safety margin of existing actuators. The additional
torque provided to existing actuators extend their life and reduce maintenance.
5. The IMPACT™ is ideal for critical applications where quick-closing actuators are required.

6. The IMPACT™ will help “self opening" valves keep their shut-off position.

Torque (Nm)
Features
Adds 50% more torque
Redirecting the air pressure into the spring chamber increases the spring end torque by 50%
and more.
The torque generated depends on the type of valves in service and the operating conditions.
The additional torque can be above 200%.

The IMPACT™ typical behavioral reaction to a spring return stroke is shown in the graph
below. It is evident that the actual spring end torque is significantly higher with the IMPACT™.
One size
The IMPACT™ comes in one size only which fits all size actuators making it a simple and easy
solution for all the actuators on site or in inventory.
Used with any actuator
The IMPACT™ can be used with any type of spring return actuator, be it linear or rotary such
as: rack and pinion (single piston, double piston, four piston), Scotch-Yoke, Spring-Diaphragm,
Vane type and Worm gear.
