High Pressure Seal Bonnet Gate Valve, also known as power station gate valve, and is mainly applicable to the pipeline of the fire station in a variety of systems, cut off or connected piping media. Applicable medium: water, steam and other non corrosive media. Compared with other valve products is high temperature and high pressure, the unique self seal design, the higher the pressure, the more reliable seal. Due to the special properties of technical characteristics, conditions of formation of the products can not be replaced by other product characteristics.
[high temperature and high pressure power station welding gate valve working principle]:
High Pressure Seal Bonnet Gate Valve unique flexible gate slot design welding, automatic compensation of machining error, is suitable for the high temperature condition, the stem surface treated by precision grinding and hardening by special corrosion inhibitor filling the structure design, temperature and pressure resistant, non corrosive, automatic lubrication, reduce the opening and closing of the friction, to avoid the corrosion on the surface of the stem, two-way pressure seal design, meet the demanding requirements of various types of special conditions.
[high temperature and high pressure power station gate valve product characteristics]:
1, the pressure seal structure, flexible gate, both ends of pipe welding.
2, the stem surface after the anti – corrosion nitriding treatment, has a good corrosion resistance and abrasion resistance.
3, the valve seat sealing surface using cobalt based alloy plasma spray welding and become, wear-resistant, anti abrasion performance, valve sealing surface nitrided and hardened.
