Features of torque actuator

Based on the opinions of each user, the Torque Actuator “Type 4 and Type 5” pursues “compact”, “low air consumption” and “light weight” based on the conventional type. , An improved new product. It is an epoch-making structure that uses air pressure as the operating medium and immediately converts the vertical movement of the piston cylinder into the left-right rotational movement of the shaft.

It was originally developed as a valve drive,
● Stable and large output (same output for both braking and running)

● Long life

● Light weight

● Compactness Due to

its functions such as <br>, it has been adopted in all machine / industrial machines and automation equipment that need rotation function as well as valve use. We are.

1. Powerful and long life

Unlike conventional cylinders that change rotation by gears or levers, friction resistance is significantly reduced by six bearings, and the operating pressure is converted to torque as it is, so it is very efficient and large output can be obtained. In addition, each part is designed to be easy and affordable, maintaining high performance for a long time.

2. light

The material is made of aluminum alloy, so no excessive load is applied during piping and installation.

3. Vertical cylinder

Since the piston is moved up and down by applying operating air to rotate the shaft, the width is smaller than that of a horizontal cylinder, and it is extremely small and requires less installation area to obtain the same output than other cylinders.

4. No oiler needed

The cylinder uses a unique lubricant whose inner surface becomes a film. Since the friction resistance is very low, it can withstand continuous operation for a long time as it is and there is no need to constantly lubricate, so no oiler is required.

5. Resistant to vibration and easy to install

The connection between the torque actuator and the work piece can be easily installed on any product directly or by installing a stand in the middle. Therefore, assembly time is shorter than other cylinders, and it is easy to remove for maintenance and inspection. In addition, it is resistant to vibration, and there is no deterioration in performance and no loosening of the joints for 4G.

AT4 torque actuator

The AT4 is the basis of another type and is most widely used for valves and all equipment.

The spring type can automatically change the rotation angle in the event of an unexpected accident such as failure of the operating pressure piping and compressor, and is often used for emergency shutoff of ball valves, butterfly valves, dampers, etc. Used.

AT5 torque actuator

AT5 type is mainly used for butterfly valves. When mounting on a butterfly valve, there is no need for a mounting base, which reduces costs.
Spring type is mainly used for emergency shutoff of butterfly valves etc.
