What is a Valve Positioner? As a common control valve accessory, the valve positioner delivers pressurized air to the valve actuator so that the position of the valve stem or shaft corresponds …

Forces such as friction from packing, seals, and differential pressure all conspire to re-position the valve stem so stem travel does not precisely correlate to actuating fluid pressure. Positioners …

This comprehensive guide will explain the critical role of control valve positioners, delving into their function, the various types available, and the key factors to consider when selecting the …

Valve positioners are critical components in process control systems that precisely adjust the position of a fluid flow control valve, ensuring the valve accurately reaches the desired setpoint …

Valve positioners compare a control signal to a valve actuator's position and move the actuator accordingly. They are used with both linear valves and rotary valves.

There are a lot of different types of valve positioners out there. How do you know if you need a pneumatic, electric or electro-pneumatic positioner? In this post, we'll cover the basics of valve …
