Introduction to Z61Y Pressure Self tightening Sealing Valve Cover Handwheel Operated Cast Steel Gate Valve
The Z61Y pressure self tightening sealing valve cover handwheel operated cast steel gate valve opening and closing part is a rigid solid gate plate. The direction of movement of the gate plate is perpendicular to the direction of the fluid, and can be used for full opening or full closing. The valve body adopts integral forging, which is very suitable for high-temperature and high-pressure working conditions. The gate valve has low fluid resistance, low erosion and erosion of the sealing surface by the medium, easy opening and closing, unrestricted flow direction of the medium, no disturbance or pressure reduction, simple structure, short structural length, good manufacturing process, and wide application range.
Characteristics of Z61Y Pressure Self tightening Sealing Valve Cover Handwheel Operated Cast Steel Gate Valve
1. The middle chamber adopts a pressure self tightening sealing structure, and the higher the inner chamber pressure, the better the sealing performance. The two ends of the branch pipe are welded to meet different nozzle requirements.
2. The sealing surfaces of the gate and valve seat are made of Stellite cobalt based hard alloy by overlaying welding. The motion seal has high hardness, wear resistance, high temperature resistance, corrosion resistance, good scratch resistance, and long service life.
3. The valve stem has undergone tempering and surface nitriding treatment - it has good corrosion resistance and scratch resistance.
