Question by: Johnny S on Jan 3, 2026, 7:54 PM
got a 1/4 npt line, which way does this check valve need to face so it’ll flow right
Answer by: Customer Support on Jan 5, 2026, 2:45 PM
Flow is allowed in the direction of the arrow on the valve, and it blocks flow in the opposite direction for a positive check.
