885 Stainless Steel In-line Check Valve

Engineered for precision in compact systems, the 885 Stainless Steel In-line Check Valve delivers reliable backflow prevention in high-pressure water, oil, and gas applications. Featuring a spring-loaded design and ASME-compliant threaded ends, this valve operates flawlessly in horizontal or vertical orientations, making it ideal for space-constrained installations. With a ultra-low 1.45 PSI cracking pressure, it ensures minimal resistance while protecting systems from reverse flow damage.

Key Features & Benefits

• Spring-Loaded Precision: Rapid response to flow changes prevents backflow and water hammer, even in pulsating systems.
• 1000 PSI WOG Dominance: Rated for 100# WSP (steam) and 1000# WOG (water/oil/gas)—ideal for extreme-pressure industrial applications.
• Multi-Orientation Flexibility: Install horizontally or vertically without performance loss, perfect for tight or complex layouts.
• ASME-Compliant Threads: FNPT x FNPT ends (ASME B1.20.1-NPT) ensure leak-proof, code-approved connections.
• Low-Pressure Sensitivity: Opens at just 1.45 PSI, minimizing energy loss in sensitive systems.

Technical Specifications

• Material: Stainless steel body, spring, and trim.
• Pressure Rating: 100# WSP / 1000# WOG.
• End Connections: ½” to 2” FNPT (IPS).
• Cracking Pressure: 1.45 PSI.
• Installation: Horizontal or vertical.

Ideal For

• High-pressure hydraulic and fuel oil systems.
• Compressed air lines requiring low cracking pressure.
• Vertical pump discharge in water treatment plants.
• Industrial gas pipelines with space constraints.

Why Choose the 885 Check Valve?

Unlike traditional swing check valves, this in-line spring-loaded design eliminates orientation limitations and operates reliably in high-vibration environments. The stainless steel construction resists corrosion in harsh chemical or marine settings, while the low cracking pressure ensures efficiency in energy-sensitive applications. Trusted for critical flow control, the 885 valve combines versatility with industrial-grade durability.
