Frequently Asked Questions
What does the spring option affect?
The spring determines cracking pressure — the minimum upstream pressure needed to open the valve. Standard spring suits most plumbing applications. No-spring and light-spring versions suit low-pressure or gravity-flow systems.
Can this be installed vertically?
Yes — horizontal or vertical with upward flow. Do not install vertically with downward flow.
Is this valve made in the USA?
Yes. Apollo 61 Series check valves are manufactured in the USA, BABA and Buy American Act compliant.
