Product Usage

The welded connection globe valve is suitable for cutting off or connecting media in pipelines of various working conditions such as petroleum, chemical, hydraulic, and thermal power plants with nominal pressure PN20.0-32.0Mpa and P (54) 100V~P (57) 170V, and working temperature ≤ 540 ℃ (where P (57) 170V has a working temperature of 570 ℃). Applicable media include water, oil, steam, etc. The operation modes include manual, gear transmission, electric, etc.

Product Structure Features:

1. The product design and manufacturing shall comply with the provisions of E101 and JB/T3595-93 standards, with a reasonable structure, excellent performance, and beautiful appearance.
2. The valve chamber adopts a pressure self tightening sealing structure, and the better the sealing performance. The two ends of the branch pipe are welded structures. Welding grooves can be matched according to standards or user requirements.
3. The sealing surfaces of the valve disc and seat are made of Stellite cobalt based hard alloy, which is wear-resistant, high-temperature resistant, has good abrasion resistance, and has a long service life.
4. The valve stem has undergone quenching and surface nitriding treatment, which provides good corrosion resistance and abrasion resistance.
5. The depth of the valve cover packing box is reasonable, and corrosion inhibitors are added to the packing to ensure reliable sealing.
7. The electric globe valve is equipped with a DZW series valve electric device, which has the characteristics of small housing, light weight, comprehensive functions, and beautiful appearance. It can also be used in conjunction with a programmable computer or an electric device can be selected according to user requirements.
