Description & Features

The Brass Inline Hydraulic Check Valve Female 1/4-18 NPT Ports PSI Cracking Pressure Up to 6.00 GPM & 2000.00 PSI is a high-performance component designed for pneumatic and lower pressure hydraulic systems. Featuring a maximum operating pressure of 2000 PSI and a rated flow of up to 6 GPM this valve ensures reliability in industrial environments.

This check valve facilitates free flow in the direction of the arrow while providing a positive check in the opposite direction making it essential for maintaining optimal fluid dynamics. Crafted from durable brass the valve offers robust performance while the stainless steel ball and spring enhance longevity.

The valve's low pressure differential requirement for opening and closing ensures efficient operation. The 1/4-18 NPT ports contribute to seamless integration within various systems simplifying the installation process.

With a maximum operating temperature of 200F the valve is versatile for different industrial applications. Additionally the Delrin ball follower and stainless steel retainer provide added durability and reduced maintenance requirements.

Product Questions & Answers (2)

Question by: Dean M on Sep 3, 2025, 3:45 PM
Can this handle hydraulic oil, or is it just for air?
Answer by: Customer Support on Sep 5, 2025, 6:39 AM
This check valve is designed for both pneumatic and lower-pressure hydraulic systems, so hydraulic oil will work just fine.
Question by: Danny C on Mar 15, 2026, 3:57 PM
got an arrow on it. which way does the oil need to go for it to pass through?
Answer by: Customer Support on Mar 17, 2026, 12:37 PM
Follow the arrow for the free flow direction. In that direction the valve opens with a low pressure differential, and it blocks flow in the opposite direction with a positive check.
