Frequently Asked Questions

What is the difference between double-acting and spring-return?

Double-acting (AD) requires air to both open and close. Spring-return (AS) uses a spring to close automatically on air loss — ideal for fail-safe applications.

Which seal material should I choose?

Nitrile (Buna-N) is the standard choice for most applications. Viton is recommended for chemical or high-temperature service. Silicone is suited for extreme temperature ranges.

What valves is this compatible with?

Apollo AD/AS Series actuators are ISO 5211 compatible with Apollo and other ISO-mount quarter-turn valves. Verify torque requirements before ordering.
