With process-based industries continually seeking to make their plants more efficient, more reliable and above all safer operating environments, a number of equipment test and verification strategies have been developed to facilitate this. Where operators employ Shut Down Valves to prevent dangerous plant conditions developing, the concept of Partial Stroke Testing (PST) has been promoted to improve efficiency, reliability and safety. Unfortunately, many operators choose not to utilise PST capabilities because of the associated risk of a Spurious Trip occurring.

Key features and benefits of Camtork Tripguard System Actuators.

Key Features

Camtorc's dual supply port design divides pneumatic duties for optimised performance. One larger piston solely compresses the fail-safe spring, enabling right-sized capacity to store full mechanical energy. A smaller piston efficiently handles valve rotation. By separating spring charging and actuation functions, both systems operate at ideal pressures and flows.

Key Features

Camtorc's VSD controller revolutionises partial stroke testing by integrating intelligent position control into a single, streamlined package. The controller coordinates feedback from valve monitoring accessories and actuates using solenoids, while isolating the safety loop

Key Features

The versatile VSD controller enables various forms of valve testing to thoroughly validate performance. The full feature set provides a complete picture of critical final element health. VSD can execute full strokes for comprehensive function checks, as well as partial travel exercises to detect subtle issues without disrupting flow.

Industries

Camtorc Extreme Service Actuators are specifically designed for critical applications in the oil and gas, energy, and marine industries.

The unique cam design provides highly efficient, backlash-free operation, extending the life of seals and components.

Camtorc Extreme Actuators are constructed in 316 (CF8M) stainless steel, ensuring high integrity and superior operational life.

At the beginning of the spring stroke, it has a 15% increase in torque output, providing extra power for break torque, and at the end of the spring, the torque output is the same as the double-acting variant.

The high torque output allows for the use of smaller size actuators compared to conventional designs.

All springs are stress relieved after forming to ensure a long life.

The ambient temperature range is -20°C to +60°C (T6).

They have ATEX II 2 G IIC c T* certification (*dependent on seal materials).

The torque range for the double-acting version is 10 to 30,000 Nm.

The torque range for the spring return version at the end of the spring stroke is 10 to 20,000 Nm.

The supply pressure range for pneumatic actuators is 2 to 10 barg.
