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?
This valve is CRN registered for use in Canada.
