Attachment To Linear/Rotary Actuator Samson 3767 Electropneumatic Positioner

Product Description:

The function of the positioners is to make sure that the valve position, which is known as the "controlled variable x," is properly assigned to the input signal, or the "reference variable w." In order to achieve this, the positioners compare the input signal that is received from a control system to the travel of the control valve. This process results in an output signal pressure pst, or the "output variable y," which corresponds to the input signal received.

If the actuator is double-acting, the positioners utilize a reversing amplifier to produce two opposing signal pressures. This ensures that the actuator can effectively move in both directions, which is necessary in many industrial applications.

Overall, the positioners are a critical component in ensuring that valves are operating as intended and responding to input signals accurately. This technology helps to maintain precise control over industrial processes and maintain efficiency in manufacturing and production settings.

Applications:

There are two different types of positioners available for pneumatic control valves: single-acting and double-acting. These positioners are designed to be attached to the valves to help with their operation.

A single-acting positioner works by using air pressure to move the valve in one direction, typically to the open position. When the air pressure is released, the valve will move back to its original position. On the other hand, a double-acting positioner uses air pressure to move the valve both ways, meaning it can be adjusted to either the open or closed position.

Positioners are useful for helping with the accuracy and precision of pneumatic control valves. They can help to ensure that the valves are opening and closing at the correct times and to the correct degree, which is important for maintaining proper control over various processes.

Overall, the use of positioners can provide a number of benefits for those using pneumatic control valves. Whether choosing a single-acting or double-acting option, these devices can improve the efficiency and accuracy of valve operation in a variety of applications.
