Impact Type High Pressure High Temperature Globe Valve
The impact type high pressure and high temperature globe valve designed by Dazhong Valve Group, J61Y-25. J61Y-20 type valve is installed on water and steam pipelines with a temperature of tW450°C as an opening and closing device; J61Y-P5410V and J61Y-P5414V are installed at a temperature of 540°C It is used as an opening and closing device on the steam pipeline of °C. , The sealing ring is a formed graphite ring, and the valve body is formed by forging and welding with patented technology, and its service life is much longer than that of the cast steel valve body. The valve seat is embedded in the valve body, and the sealing surface is flat. The material of the valve seat and the sealing surface of the valve disc is made of drill-based cemented carbide plasma spray welding, and the surface of the valve stem is treated with anti-corrosion nitriding.
61Y-25. The J61Y-20 valve is installed on the water and steam pipes with a temperature of tW450°C as an opening and closing device; J61Y-P5410V and J61Y-P5414V are installed on the steam pipes with a temperature of 540°C as an opening and closing device. For opening and closing devices.
The pressure self-tightening sealing structure is adopted. The sealing ring can be tightened by rotating the nut. The sealing ring is a formed graphite ring. The higher the medium pressure, the better the sealing performance.
The valve body is formed by forging and welding with patented technology. It has a beautiful appearance, high strength, no leakage, and its service life is much longer than that of the cast steel valve body.
The impact handwheel is used to reduce the operating force.
The valve seat is embedded in the valve body, with a flat seal. The material of the valve seat and the valve disc sealing surface is made of drill-based cemented carbide plasma spray welding, which has good wear resistance and scratch resistance. The surface of the valve stem is resistant to corrosion. Nitriding.
It can be installed in any position of the pipeline, and the flow direction of the medium is positive flow from bottom to top.
