2 inputs determine the right speed & flow control.
A distributor-facing pre-quote checklist. If the customer answers most of these at the first call, the second call is the quote.
- 01 How does the customer plan to tune cylinder speed — and is there a downstream concern about end-of-stroke slam?Two speed controllers per double-acting cylinder, meter-out, threaded into the cylinder ports. This is the second SKU on every cylinder quote and the most common new-install miss. If the customer asks "can we just throttle the pressure?" — no. Reducing pressure cuts force, not speed; cylinder stalls under load. If the customer asks for "a flow control," verify they don't mean a speed controller (about 1/3 of those requests do).
- 02 For each cylinder — is the cylinder holding a load, and what's the failure mode if supply pressure is lost?Drives the pilot-operated check valve sale. Two pilot-op checks at every cylinder that holds a load against gravity or external force — lift platforms, clamp stations, indexing stages, pallet positioners. $20-50 of check valves prevent the kind of power-event failures that cause OSHA recordables. The integrator who built the machine often skipped these as a cost-cut decision the customer regrets after the first power event.
