Directional control valves are simply required to change direction of air flow inside pipes and compressed air systems. To see their actual working, let us go into deep about the concept how directional valves are used in actual and how they are manufactured in India and worldwide.
Directional control valves can be used for variety of applications. For a specific task, there may be certain changes in design and configuration of control valves. Sometimes, experts have to use combination of valves to complete one particular task accurately.
Let us discuss about different configuration options for control valves first. These are -
- 2-Way Valve Configuration: - As the name suggest, these valves have two ports to control flow of air inside compressed air systems. They are operated electrically for proper maintenance of air flow.
- 3-Way Valve Configuration: - They are almost similar to 2-way valves but available with one additional port to exhaust the air steam. They may be available in open or closed configurations.
- 4-Way Valve Configuration: - As the name suggest, these control valves have four ports opened together and works alternatively. The only problem is that they are pretty much difficult and confusing to install.
Maintenance for directional control valves
Maintenance schedule assures that directional control valves will operate at their best with maximum efficiency. Regular checkups are necessary to assure flawless performance and continuous operations for several projects.
The directional control valves maintenance procedures will check either lubrication is in proper state or not. The person who conducts maintenance for valves should be well educated and experienced to handle this responsibility.
For the experts, it is necessary to note down dates and time for maintenance. Also make sure that all necessary steps have followed wisely. As per experts’ suggestion, maintenance once in a year for directional control valves is mandatory.
