Common Pneumatic Control Valve Problems

Pneumatic Control ValvesPneumatic control systems primarily depend upon the many small parts that make up the system. Knowing when and how to replace malfunctioning parts is essential to effective and safe work. At a minimum, issues can cause work slowdowns, and in a worst-case scenario, it creates dangerous working environments. Below, we want to go over the most common signs that it is time to replace pneumatic control valves.

Pneumatic Control Systems

A pneumatic control valve is designed to control the flow of gases within a closed system. Control valves take direction from controllers that send signals, which means the system has a set point to maintain. Valves are responsible for controlling the rate of flow within pneumatic control systems. Pneumatic control valves are used within medical devices, such as anesthesia machines. If systems malfunction, it could cause patients to die.

Internal valve leaking is one of the most common issues, but finding those leaks is challenging. An acceptable amount of leakage is allowed, but anything beyond that causes trouble. Valve leaking is often caused by internal wear, as will a poorly set up actuator. Lastly, it would help if you were mindful of improperly set up positions that are incorrectly configured and often cause leaks.

External leakage is a lot easier to catch than internal leakage. Gas is released from the system and into the atmosphere, sometimes creating health hazards. Common causes of leaks include excessive packing and improper maintenance.

Valve failure often requires replacements. When a pneumatic diaphragm wears out, it is time to get replacement parts.
