The Beaver Cast Steel Bolted Bonnet Swing Check Valve is a heavy-duty, non-return valve designed to API 600 standards for petroleum and natural gas applications.
These valves, available in C31, C32 and C33 models, provide a tight seal in both horizontal and vertical positions. They are also fully ported and spherical for minimal resistance, flow turbulence, and stress on the valve.
The valve’s hinge arm pivots on the hinge pin which is attached near the disc’s center of gravity. The hinge arm also has a built-in disc stop to provide a positive stop in the open position. The disc surface is mated to the seat ring to ensure a tight seal. The seat ring can be forged and rolled in one piece and seal welded.
