API 2" Fig1502 MxF Clapper Type Top Entry Check Valve 15000psi WP

Clapper check valves, unlike dart style valves, are designed for fluids heavily laden with proppants, ball sealers and other solids. The threaded seat features a self-locking design to prevent coming loose during operation and is replaceable for extended product life.

The clapper comes fully coated in urethane to reduce delamination while offering consistent sealing. The enhanced hanger is machined with a flat to align within the body to prevent rotation during operation, and contains fewer components to manage and maintain.

These clapper check valves are manufactured in 2-inch, 3-inch and 4-inch sizes for operating pressures up to 15,000 psi. Hammer union end connections are available in standard or reverse flow. The clapper check valve should be installed with the flow direction arrow machined on the body aligned with the line’s flow direction.

Check valves Have Three types: top entry type check valve, in-line clapper type check valves, and dart type check valves.
