Check valve is suitable for high temperature and high pressure power station Class1500 ~ 2500 lb, working temperature - 29 ~ 570 ℃ in the petroleum, chemical, thermal power plant under various working conditions such as the pipeline.Applicable medium: water, oil, steam, etc.
Product features:
1. The product design and manufacture according to ANSIB16.34, standard E101, can be used with imported equipment equipped with.
2. The valve lumen self-tightening seal structure is adopted, and the inner cavity pressure, the higher the sealing performance, the better.Branch pipe at both ends for 3 for butt welding on both ends of the branch pipe, different to meet the demand of the takeover.
3. Pressure valve selects high quality alloy steel manufacturing, good high temperature performance, high pressure, durable, safe and reliable.
4. The disc and seat sealing surface using department too vertical (stellite) cobalt-based hard alloy surfacing and become, wear-resisting, high temperature resistance, good abrasion resistance, long service life.
5. Disc around seat outside the pin shaft rotation, cut off onslaught.
6. Built in pin shaft structure, reducing leaked funnelled, use more reliable. |
