How It Works
Multi-Cylinder Sequencing
When multiple cylinders share a pump, sequence valves ensure they operate in order. Each cylinder requires a specific pressure based on its load and area:
P_cyl = Load / Area = Load / (pi × bore^2 / 4)
Sequence Valve Settings
Each sequence valve is set above the operating pressure of its cylinder plus a margin (typically 50-200 psi):
P_seq = P_cyl + margin
Cycle Time
Cycle time per cylinder = volume displaced / flow rate:
t = (Area × Stroke) / (Flow × 231) seconds
Cylinder Sequencing
Configure 2-4 cylinders with bore, rod, stroke, and load to determine sequencing and cycle time.
