Product Usage
The J41H and J41Y high temperature and high pressure globe valves produced by Lianggu valve Co., Ltd. are suitable for the pipelines of various systems in petroleum, chemical, hydraulic and thermal power plants with a nominal pressure of 150LB to 2500LB and an operating temperature of 570 ℃. Pipeline medium.
Features
1. The valve cavity adopts pressure self-tightening sealing structure, the better the sealing performance. Both ends of the branch pipe are welded structures. Welding groove can be matched according to standard or user requirements
2. The sealing surfaces of the valve disc and valve seat are made of Stellite cobalt-based hard alloy, which is wear-resistant, high-temperature resistant, good scratch resistance and long service life
3. The valve stem is tempered and surface nitridized, which has good corrosion resistance and scratch resistance.
4. The depth of the stuffing box of the valve cover is reasonable, the filler is added with corrosion inhibitor, and the sealing is reliable
