CAA-810

Why Choose the CAA-810?

Wide Thrust t Range: Available in multiple sizes to deliver powerful thrust from hundreds to tens of thousands of Newtons, meeting the demands of various operating conditions.
Fail-Safe Function: An integrated spring automatically moves the valve to a preset safe position (normally open or normally closed) upon loss of air supply, ensuring production safety.
Robust and Durable: Designed for harsh industrial environments with a long operational life, reducing maintenance costs and downtime.
Reversible Action: The actuator’s mode of operation (air-to-open or air-to-close) can be easily reversed in the field, offering flexibility for different application scenarios.

Temperature-40°C to 100°C (-40°F to 212°F)

Key Features

Wide Thrust Output Range

Available in multiple actuator sizes to provide thrust forces ranging from several hundred to tens of thousands of Newtons. Suitable for small regulating valves as well as heavy-duty process control applications.

Integrated Fail-Safe Protection

Built-in spring return mechanism automatically drives the valve to a preset safety position (Fail-Open or Fail-Closed) upon air supply loss, ensuring plant safety and process protection.

Reversible Action

Supports air-to-open and air-to-close configurations. The actuator action can be easily reversed in the field, offering flexibility for various control philosophies.

Rugged Industrial Construction

Heavy-duty diaphragm housing and corrosion-resistant components ensure reliable performance in harsh industrial environments.

High Control Accuracy

Designed for precise linear motion, providing excellent compatibility with positioners and control systems for stable modulation.
