2, the structure length by E101, JB/T2766, GB/T15188.1 ANSIB16.10 GB12221 standard or according to user requirements.
3, pressure - temperature level by E101, JB/T3595 API598 GB9131 prescribed standards.
4, according to the welding groove size GB12224, JB/T3595, ASME B16.25 ANSIB16.25 standard rules or according to the size of the user piping requirements
High pressure lift check valve structure features:
1, the overall disc quenching, and can move up and down in the body, medium backflow, medium pressure and spring automatic valve closed.
2, the valve body, valve cover are all die forgings.
3, on the seat sealing surface using cobalt-based hard alloy plasma spray welding surface. Wear resistant, good abrasion resistance.
4, the check valve should be installed in horizontal pipe runs medium flow from the bottom to upper or flow.
