High pressure flange check valve-Power station valve series-电站阀厂家-上海冠环阀门制造有限公司

Product overview

The high pressure flange check valve is composed of a valve body, a valve disc, a spring and a central shaft. Widely used in pressure PN16-45MPa, temperature -20-+450℃ water, oil, natural gas pipeline system and oilfield system.

Product characteristics
1, the structure length is very short, small volume, light weight.
2, the valve is the whole structure, simple and compact, the impact is small when the valve is closed.
3, can be installed horizontally or vertically, light weight, do not need to set support for the valve.
4, the flow path is smooth, the fluid resistance is small, the valve disc can be fully opened under a small pressure difference.
5. The sealing surface of valve disc and seat is made of cobalt-based cemented carbide plasma spray welding.
