What Are Process Control Valves? 5/2 Way Pneumatic Valve are critical to the establishment of an efficient process and smooth running over the lifetime of a system. The controller sends signals to the valves which can change the size and direction of fluid flow, and in turn affect other process parameters, such as liquid level, temperature and pressure.
How to Choose a Control Valve?
There are many types of valves available, each having its advantages and limitations. The basic requirements and selection depend on their ability to perform specific functions such as:
Ability to throttle or control the rate of flow.
Lack of turbulence or resistance to flow when fully open as turbulence reduces head pressure.
