Product details

Power station check valves, also known as power station special valves, are mainly suitable for piping of various systems in thermal power plants to prevent medium backflow, prevent the pump and its driven motor from reversing, and release the medium inside the container. Station check valves may also be used on lines where the pressure may rise to an ancillary system that exceeds the pressure of the main system. Applicable medium: water, steam and other non-corrosive media. Power station valves and other products compared to the valve is characterized by high temperature and pressure, a unique self-sealing design, the higher the pressure, the more reliable sealing. Due to the characteristics of performance technology, special conditions of the product also formed the characteristics of other products can not be replaced. End of the stop valve to connect the majority of welded structures.

Structural characteristics
1, high-pressure check valve chamber using self-tight pressure seal structure, the higher the media pressure, the better sealing performance. 
2, the valve disc, seat sealing surface made of cobalt-based hardfacing welding, wear-resistant, high temperature, anti-abrasion performance, long service life. 
3, both ends of the branch pipe butt welding connection, welding groove can be produced according to the standard or user requirements, to adapt to different takeover requirements.
