What are directional control valves?Show answer
The number of ports tells you how many connections the valve has (supply, output(s) and exhaust(s)); the number of positions tells you how many ways it can switch.
What is matching the valve to the cylinder?Show answer
This is the core rule: 3/2 for single-acting, 5/2 for double-acting, because a double-acting cylinder needs air routed to two sides in turn.
