Frequently Asked Questions

Valve Selection & Sizing Questions

Q: How do I determine the correct SAE valve size for my application?

A: Calculate required flow using cylinder bore area, stroke length, and desired cycle time. Select valve Cv providing 20-30% margin above calculated requirement. The catalog includes sizing worksheets and examples.

Q: Can Series 80 and Series 84 valves mount on the same sub-bases?

A: Yes, both series conform to SAE J2051 mounting interfaces, allowing interchange on common sub-bases within the same SAE size.

Q: What's the difference between spool/sleeve (Series 80) and poppet (Series 84) designs?

A: Spool/sleeve valves offer faster response and higher flow but require cleaner air. Poppet valves provide better contamination tolerance and zero leakage but slightly slower response times.

H3: Installation & Maintenance Questions

Q: What level of air filtration is required?

A: ROSS recommends 40-micron filtration per ISO 8573-1 Class 4 minimum. Series 80 benefits from 25-micron filtration for optimal life. Series 84 tolerates 40-micron adequately.

Q: How often should SAE valves be serviced?

A: In properly filtered systems, SAE valves typically operate 5-10 years without service. Annual external inspection and function testing recommended. Internal service only when performance degrades.

Q: Can I convert from internal to external pilot in the field?

A: Yes, Series 80 and 84 valves support field conversion by plugging internal pilot port and connecting external pilot supply. Consult catalog for conversion kit part numbers.
