The Solution

The use of a Contrac continuous electric actuator ensures ideal positioning of the water spray control valve.

Even high temperature models with ambient temperatures up to 85 °C can achieve S9-100 % duty cycles without restriction.

The special design of the Contract actuator, with oil-lubricated spur gears and electrical components for S9-100 % duty cycles, allows high precision in the positioning of the sprinkler valve.

High precision and true continuous positioning of the water spray valve is achieved.

Due to the special design and operating principle of the Contrac actuator, the dead band is only ±0.05 %.

This precision allows for highly accurate positioning of all types of valves over the entire range.

All components are IP66 rated and can be used even under the harshest environmental conditions.
