Explore company information and manufacturing capabilities, then discuss the scope of your project with a relevant supplier.
A spool is typically a sliding cylindrical part with lands/grooves for multi-port flow direction, common in directional valves. A poppet is usually a seated design that lifts vertically for on/off or proportional control, often used in check or relief valves.
Regularly inspect for wear, corrosion, or contamination; use filtered fluid; ensure proper lubrication; and follow manufacturer's service intervals. Cleanliness is critical to prevent sticking or leakage.
