Spesak stop valve steam heat transfer oil stop valve high temperature and high pressure stop valve

  Product name, model and specification pressure material bellows stop valve wj41h dn15-500mm PN1 6-4
0mpa cast steel; Stainless steel I
Introduction to bellows stop valve wj41h bellows stop valve is suitable for high-temperature heat transfer oil, liquid ammonia and other media with nominal pressure of pn1
6 ~ 16MPa and working temperature of - 29 ~ 350 ℃
It is widely used in other gas systems such as petrochemical industry, chemical fiber textile, plastic papermaking, electric power steel, printing and dyeing rubber, natural gas and other industrial fluids such as ethylene glycol
2、 Structural features of bellows stop valve 1
The bellows stop valve has reasonable structure and sealing, Double solid bellows sealing design (bellows + packing), zero leakage of valve rod
No fluid loss, improve plant equipment
2
The sealing surface is overlaid with Co based cemented carbide, with good wear resistance, corrosion resistance and friction resistance
3
The valve rod is quenched and tempered and surface nitrided, with good corrosion and friction resistance; the indication of valve rod lifting position is more intuitive
