CV3-40038 | Stainless Check Valve 5800 PSI 3/8 F x 3/8 F Ports

CV3-40038 | Stainless Check Valve 5800 PSI 3/8 F x 3/8 F Ports

• The AR CV3-40038 is a stainless-steel, high-precision check valve engineered by Annovi Reverberi to maintain safe, one-direction flow in high-pressure water systems.
• Rated for up to 5,800 PSI and built with dual 3/8-inch female NPT ports, it prevents backflow and pressure reversal that can damage pumps, hoses, and instrumentation.
• Compact design combines strength, corrosion resistance, and flow efficiency for demanding cleaning, industrial, and process-water applications where pressure integrity is critical.

Construction & Materials

• Body machined from high-grade stainless steel for superior resistance to corrosion, scale, and chemical wear versus brass or plated-steel valves.
• Precision-bored internal passage maintains tight tolerances and an ultra-smooth flow path, minimizing turbulence and pressure drop.
• Internal geometry reduces dead zones and stagnant areas, limiting the risk of cavitation and contamination—ideal for filtered, softened, or reclaimed water systems.
• High strength-to-weight ratio supports use in marine, industrial, and commercial installations where durability and low maintenance are priorities.

Flow Control & Backflow Protection of CV3-40038

• Stainless-steel, spring-loaded poppet opens automatically when forward pressure exceeds the calibrated spring force, allowing smooth flow with minimal restriction.
• When reverse pressure occurs, the poppet seats instantly against its precision-machined seat, sealing the passage and blocking backflow into upstream components.
• Rapid closing action helps absorb hydraulic shock during shutdowns or trigger cycling, protecting plungers, seals, check assemblies, and hoses from reverse-pressure spikes.
• Maintains pump prime and supports consistent outlet pressure, improving the performance of downstream guns, injectors, unloaders, and spray accessories.

Installation & Integration

• Dual 3/8-inch female NPT ports connect easily to standard fittings, manifolds, and hose assemblies.
• Compact footprint allows installation in confined spaces or retrofit applications where larger check valves are impractical.
• Ideal placement near pump outlets, discharge manifolds, or critical branch lines to create a robust barrier against reverse flow.
• Simple commissioning: orient the flow arrow, apply PTFE tape or thread sealant to clean threads, tighten to spec, and verify leak-free operation.

Applications

• Professional pressure washer rigs, fleet wash stations, and industrial washdown systems.
• Agricultural sprayers and high-pressure water-distribution systems.
• Manufacturing plants and process-water circuits requiring stable, one-direction flow.
• Marine and commercial installations where corrosion resistance and pressure stability are essential.

CV3-40038 Maintenance & Serviceability

• Internal spring and seat assembly designed for thousands of cycles at high pressure, maintaining consistent sealing over time.
• Valve can be removed with standard tools for inspection and cleaning of the poppet and seat to remove debris or mineral buildup.
• Reassembly is straightforward; reinstall with thread sealant or PTFE tape for leak-free service under vibration and temperature swings.
• Minimal routine maintenance beyond periodic checks during scheduled service intervals, keeping downtime low.
