5/2 vs 5/3 Pneumatic Valve Centers: Closed, Exhausted and Pressurized
Compare 5/2 and 5/3 valve stop behavior: closed, exhausted and pressurized centers, solenoid memory, pilot-air loss and cylinder restart.

Inputs to write down before a bore is chosen: load, pressure at the work port, stroke and mount.
Start here
Record the load and the pressure at the cylinder port before you look at a catalog bore.
Cylinder selection questions uses a published worked example for a vertical lift, then shows where to write your own load and port pressure. Double-acting pneumatic cylinder sizing: force and air consumption evaluates ISO 15552 and ISO 6432 extend and retract force equations, dynamic load factors, ISO 8778 free-air consumption with tubing dead volume, cushioning, Euler buckling, and rodless actuators. 5/2 vs 5/3 directional-valve centers compares closed, exhausted and pressurized centers, solenoid memory, air-loss behavior and cylinder restart. Pneumatic flow control valve sizing: meter-out vs. meter-in speed controllers covers unidirectional throttle-check architecture, ISO 1219-1 symbols, meter-out vs. meter-in stick-slip physics, ISO 6358 sonic conductance C sizing, and quick exhaust valves.
