This Brass Inline Hydraulic Check Valve is engineered for efficient fluid management in pneumatic and lower-pressure hydraulic systems. Featuring female 1/4-18 NPT ports, it facilitates free flow in one direction while maintaining a positive check in the opposite, thanks to its low-pressure differential requirement for opening and closing. Constructed from durable brass, this check valve can handle up to 3.00 GPM and withstands a maximum operating pressure of 2000 PSI. With a cracking pressure ranging from 1 to 2.5 PSI and a Cv factor of 0.5400, it ensures reliable performance in various industrial applications.
The valve is part of the renowned Deltrol Fluid Products line, known for its quality and reliability. Its robust design makes it suitable for non-shock service conditions. The model offers versatility with materials available in brass, carbon steel, or stainless steel, catering to different system requirements.

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.
