Description & Features

The Steel Inline Hydraulic Check Valve, Female 3/8-18 NPT Ports, PSI Cracking Pressure, Up to 10.00 GPM & 5000.00 PSI, ensures reliable performance in high-pressure hydraulic systems. Constructed from robust steel materials, this valve supports a maximum operating pressure of 5000 psi and a rated flow of up to 10 GPM, catering to demanding industrial applications.

Featuring a 3/8-18 NPT port size, this check valve guarantees a secure fit and seamless integration into existing systems. The valve operates with a cracking pressure range between 1 and 2.5 psi and boasts a high CV factor of 3.3000, facilitating unimpeded fluid flow in one direction while ensuring a positive seal in the opposite direction.

The components, including the ball and spring manufactured from stainless steel and a Delrin ball follower, exhibit durability and longevity under rigorous conditions. The maximum operating temperature reaches up to 200deg;F, making it suitable for varied environments. Designed to deliver high flow rates and minimal pressure differential, this valve is an excellent choice for maintaining optimal hydraulic system efficiency.

Question by: Hubert C on Jan 7, 2026, 8:54 PM
Is this check valve suitable for hydraulic systems?
Answer by: Customer Support on Jan 9, 2026, 5:59 PM
Yes, steel valves like this one are specifically intended for use in hydraulic systems. Brass versions are for pneumatic or lower pressure applications.

got a flow arrow on it, but what’s it actually do in plain terms?
Answer by: Customer Support on Aug 24, 2025, 6:49 AM
Lets oil flow freely one direction, then shuts off tight in the opposite direction so you do not get backflow.
Question by: Dwight G on Mar 9, 2026, 9:37 PM
does this valve work for standard hydraulic lines runnin at high pressure, or is it more of a light duty thing?
Answer by: Customer Support on Mar 11, 2026, 8:03 AM
Rated for up to 5000 PSI and 10 GPM, this one holds up in full hydraulic service without issue. The steel body is built for that kind of demand, unlike the brass version which is better suited to pneumatic or lower pressure hydraulic work. Cracking pressure sits between 1 and 2.5 PSI, so it opens easy and seals back up clean once flow stops.

got a 3/8-18 npt line, is this check valve female ports on both ends or am i gonna need adapters
Answer by: Customer Support on Feb 3, 2026, 7:57 AM
Both ports are female 3/8-18 NPT, so it threads onto male 3/8-18 NPT fittings on each side.
