The new Garlock actuator for valves

The Scotch Yoke principle – characterized by its high torque.

Garlock‘s pneumatic part-turn valve actuator transmits force from the piston to the shaft by means of a lever
arm system (Scotch Yoke principle). This principle yields up to 20% savings during force transmission
compared to the rack and
pinion principle because the highest force is generated at the highest valve torque. This cost-effective
principle and a compact design with reduced dimensions enable easy
handling and minimum air (energy) consumption.

The product line features double acting actuators with a torque ranging from 7 Nm to 8000 Nm and single
acting actuators with 5 Nm to 2600 Nm. Service life is considerably extended by the Garlock actuators made
of very sturdy anodized aluminum housings.
They boast smooth running properties and gentle starting behavior that extends valve life and guarantee high
corrosion resistance. For very aggressive atmospheres Garlock special coatings made of epoxy resin,
nickel or PTFE are the right choice. The high-quality design guarantees a service life of at least 2 million
switching cycles. The efficiency of the actuators is furthered optimized by the rolled bearing surfaces,
resulting in minimization of the stick-slip effect and durable and reliable piston sealing.
All actuators are manufactured in compliance with the highest quality standards.

We are quality certified according to ISO 9001.
