Titan Flow Control CV 50-DI-B Flanged (Flat Face) Ductile Iron Globe Style Silent Check Valve w/ Bronze Seat & Disc - ASME Class 150

Titan Flow Control's check valves are automatic shut-off valves that are commonly used for preventing backflow or drainage in a piping system. Often applied on the discharge side of pumps, check valves prevent the system from draining if the pump stops and protects against backflow, which could harm the pump and/or other equipment.

Note: This valve is intended for liquid service that does not exceed 10 ft/sec. It is designed for steady flow conditions and is not recommended for use in reciprocating pump, compressor or other type of physical/thermal shock-load applications. This valve is not recommended for steam service or flow media that contains solids. It should be installed at least five pipe diameters downstream from any turbulence producing components. Flow straighteners may be required in certain applications.

Features

• Designed for Long Service Life: Utilizes straightening vanes that reduce turbulence in incoming flow, thus minimizing noise, vibrations erosion, cavitations, and other factors that could result in premature valve failure
• Minimal Head Loss: Head loss is minimized by the integral straightening vanes that help create laminar flow - A large cross-sectional area also lessens pressure drop across the check valve - Unlike typical conical spring constructions that restrict flow, the CV 50 has a compression spring coupled with a small stem guide that allows for an unobstructed flow path
• Quick Closure to Reduce Water Hammer: Silent shut-off is achieved via the fully automatic, spring assisted disc that closed near zero flow velocity - The lightweight, center guided disc design creates a positive shutoff prior to flow reversal and helps to keep slamming and surges to a minimum
• Metal to Metal Seats: Precision machined sealing surfaces allow the CV 50-DI to maintain a tight seal that meets or exceeds API 598 leakage requirements - Resilient seats are also available to provide bubble tight seals - Sealing is further improved by an additional gasket assembled with the seat independent of the flange gasket
• Versatile Design: Clearance within the CV 50's body allows a butterfly valve to be installed directly on the outlet side of the valve without extra piping - Because the valve's trim is interchangeable, various seats, discs, and springs are available and easy to replace - Exotic spring material, such as monel or inconel 750-X, can easily be substituted for the standard stainless steel - Please call 1-800-333-3331 for more information
