CV Series Industrial Check Valve in Brass with NPT Female Spring Action - Configurable in sizes

Hermetic Sealing and Installation Versatility

The Dixon CV Series is the ideal solution to prevent backflow in systems where total sealing is critical. Unlike metal-seated valves that can allow small leaks, the CV Series uses an NBR (Nitrile) Soft Seat. This ensures a "Bubble-tight Seal", guaranteeing that not a single drop of fluid returns through the pipe once the valve closes.

Its internal mechanism operates via a spring that pushes the closing disc. This offers two major advantages:

1. Universal Installation: It can be installed in vertical (upward or downward flow) or horizontal pipes, as it does not rely on gravity.

2. Quick Closing: The spring closes the valve immediately when flow stops, helping to reduce "water hammer."

Key Technical Features:

• Spring-Actuated: Very low cracking pressure of only 0.50 PSI, allowing flow with minimal resistance.

• NBR Seat: Elastic material that absorbs small particles and ensures total hermeticity, ideal for water and air.

• Optimized Flow Design: Internal profile designed to minimize pressure drop when the valve is fully open.

• Pressure Range:

  • Sizes from 1/2" to 2": Withstand 400 PSI WOG.

  • Sizes from 3" to 4": Withstand 175 PSI WOG.

Technical Specifications

Recommended Applications

• Water Pumping Systems: On the suction (foot valve) or discharge to keep the pipe filled.

• Air Compressors: To prevent air from the tank returning to the compressor head.

• Agricultural Irrigation: Prevention of drainage in sloped lines.

• Vertical Installations: Where a swing check would not work.
