Structural characteristics of electric flange globe valve
1.Carefully selected materials,in compliance with relevant domestic and international standards,with a reasonable structure and beautiful appearance.
2.The sealing surface of the valve disc and seat is made of iron-based alloy or Stellite cobalt based hard alloy,which has good wear resistance,high temperature resistance,corrosion resistance,abrasion resistance,and long service life.
3.The valve stem has undergone quenching and surface nitriding treatment,providing excellent corrosion resistance and abrasion resistance.
4.Various piping flange standards and flange sealing surface types can be adopted to meet various engineering needs and user requirements.
5.The valve body material variety is complete,and the packing and gasket can be reasonably selected according to actual working conditions or user requirements,which can be suitable for various pressure,temperature,and medium working conditions.
6.The reverse seal is made by connecting the sealing seat with threads or welding austenitic stainless steel on the body,ensuring reliable sealing.The replacement of the packing can be carried out without stopping the machine,which is convenient and fast,and does not affect the operation of the system.
7.Equipped with DZW series multi turn electric device,it has a small housing,light weight,full functions,and can be used with remote computers.It can also be optionally equipped with electric devices according to user requirements.
