Weld-connected gate valve and stop valve are suitable for the pipeline of PN1.6~32.0MPa,P54/100V~P57/170V,a working temperature <= 540°C (570°C for P57/170V) in various systems of petroleum. chemical industry, steam power, hydraulic etc.to cut off and get through the medium. The suitable media are: water, steam, oil goods, acid media and so on.
Conforms with the requirements of the domestic and foreign advanced standards.The middle cavity of the valve uses the pressure self-tightening sealing structure,the two ends of the branch pipe use welded structure and the welded groove can be connected per eight the standard or the required one by users.Of a reliable seal,good performance and nice modeling.
The sealing faces of both disc and seat ring are made by means of means of built-up welding with either iron-based alloy or Stellite Co-based carbide alloy upon different requirements,wearable,high temperature resisting,corrosin resisting,good friction resisting and long duration.
The stem,after the modified and surface nitriding treatment,has a good friction and corrosin resistance and a back-seal structure to ensure the valve no leak outward from the stem when opened during running and able to replace the stem packing.
The valves with a large or a middle apertures can use the internal by-pass structure and be set with a rolling bearing and a thrust bearing, resulting in flexible open-close.
The electric stop valve is fitted with SMC valve electric actuator,features a small casing,light weight,full functions and a nice outlook and can be used either with a program controlled computer or an electric actuator upon the user requirement.
