Overview
- CV5-55038 – AR Stainless Check Valve, 3/8 in NPT | 7,980 PSI
- High-pressure stainless check valve engineered by Annovi Reverberi to provide dependable one-way flow, fast backflow shutoff, and stable pressure retention in demanding water and hydraulic circuits.
- Rated to 7,980 PSI with dual 3/8-inch female NPT ports, it installs cleanly at pump outlets, discharge manifolds, and test or process lines to form a compact barrier that keeps reverse flow from propagating upstream.
Construction & Materials
- Body machined from corrosion-resistant stainless steel to resist rust, pitting, and chemical attack in wet, detergent-rich, or mildly aggressive environments.
- Tight dimensional tolerances and a smooth internal bore minimize turbulence, pressure loss, and the conditions that lead to cavitation or vibration.
- Compact form factor fits tight panels and retrofit manifolds without crowding hoses, gauges, or test ports.
Flow Control & Backflow Protection
- Internal stainless, spring-loaded poppet opens automatically when forward pressure overcomes the calibrated spring force, allowing free flow in the intended direction.
- On pressure reversal, the poppet snaps closed against a precision-lapped stainless seat to create a bubble-tight seal that blocks backflow.
- Rapid, repeatable closure helps absorb hydraulic shock during shutdowns, trigger cycling, or emergency stops, preventing reverse-pressure spikes from reaching pumps, seals, hoses, and instruments.
- CV5-55038 Supports high volumetric efficiency and stable delivery to downstream regulators, unloaders, and spray tools.
Installation & Integration of CV5-55038
- Dual 3/8 in female NPT ports simplify leak-free connections using common fittings.
- Ideal near pump outlets, discharge manifolds, or critical branch lines to stabilize line behavior and protect upstream equipment.
- Easy commissioning: orient the flow arrow correctly, apply PTFE tape or thread sealant to clean male threads, tighten to specification, and verify leak-free operation and prompt reseat during initial cycling.
- Optimized internal geometry keeps the passage full-size for the thread class, allowing efficient flushing when switching between detergents and clear water.
Applications for CV5-55038 Stainless Check Valve
- Industrial cleaning plants, fleet wash facilities, and portable pressure-washer skids or trailer rigs.
- Process water loops, surface preparation and coating removal systems, and general high-pressure service.
- Hydraulic and test circuits where reverse flow could damage pumps, gauges, or metering devices.
- Multi-pump arrays where check valves prevent idle pumps from being driven backward by neighboring units.
Maintenance & Serviceability
- Spring and seat engineered to withstand thousands of high-pressure reversals without loss of preload or sealing accuracy.
- Routine care typically limited to scheduled inspection for mineral deposits or debris in systems using hard or reclaimed water.
- Valve can be removed with standard tools, cleaned, and reassembled to original torque; stainless construction and polished poppet interface keep friction low and closing force predictable over time.
Why Choose the AR CV5-55038 Stainless Check Valve?
- Stainless 3/8 in NPT check valve rated to 7,980 PSI for serious high-pressure duty with generous headroom for transient spikes.
- Delivers tight, repeatable backflow prevention that stabilizes line pressure, reduces pulsation, and helps unloaders and regulators hold a consistent setpoint.
- Protects high-value pumps and accessories while improving spray consistency, surface results, and overall system reliability.
- Compact, strong, and easy to integrate, it reflects Annovi Reverberi’s emphasis on precise machining, robust materials, and dependable field performance in demanding high-pressure systems.
