Rotary check information for pressure PW1.6-16.0MP; C5s 150-2500, working river -29-570'0 petroleum, chemical, pharmaceutical, fertiliser, electric power industry and other conditions of the pipeline, to prevent the backflow of the medium. Its main structural features are.
1. Reasonable structure, reliable sealing, excellent performance, beautiful shape.
2. The sealing surface is surfaced with bullion carbide, which is wear-resistant, corrosion-resistant, good anti-injury performance and long service life.
3. The internal pin beat structure, reduce the external leakage point, the use of reliable.
4. When the pressure ≥ 16.0MPaCass1500, the smoke door cavity adopts self-tightening sealing structure, the higher the medium pressure, the better the sealing.
5. The material of parts and flange, butt-welding end size can be very according to the actual working conditions or user requirements for reasonable selection to meet a variety of engineering amphibious
