In any pneumatic circuit, control valves are the major component. These directional control valves are used to blocking airflow or directing the sequence of operation. To classify directional control valves, you should consider the flow paths among various conditions of service. Flow paths, the number of ports and valve position are the important factors.
2-way 2-position valves
This comprises of two ports associated with an entry that is opened or hindered to control move into the valve. As a rule, an electrically actuated solenoid moves the valve spindle or poppet to address stream. The valve gives a simple on-off capacity, which numerous frameworks use to interlock, detach, and interface different framework parts.
3-way 2-position valves
Comprise of three ports associated through entries inside a valve body. The devices pressurize and deplete one exit port to manage a single acting barrel, or guide another valve. Three-way pneumatic valves guide pressurized air to the top end surface of the container. Moving the spool to the next great position pieces stream and weight to the actuator. The actuator is associated with the exit port, in this way spring power or gravity must give back the bar to its unique position.
Three-way pipes may likewise be utilized as a part of sets to work a double acting chamber, in this way supplanting a 4-way valve. Consider usage of combined 3-path valves rather than a 4-way when high chamber velocities are necessary. Tight coupling of 3-path valves to the chamber ports diminishes barrel back weight and weight drop in the lines, allowing higher barrel speeds. The valves are likewise used to spare packed air in exceedingly cyclic applications or when the middle positions are required. Spring power is given back to its original position by connecting actuator to exit port.…
