Structural features of electric stop valve
, well-selected materials, in line with relevant domestic and foreign standards, reasonable structure, and beautiful appearance.
The sealing surface of the valve disc and valve seat is made of iron-based alloy surfacing or Stellite cobalt-based hard alloy surfacing, which has good wear resistance, high temperature resistance, corrosion resistance, scratch resistance, and long service life. .
The valve stem has been tempered and surface nitrided, and has good corrosion resistance and scratch resistance.
Various piping flange standards and flange sealing surface types can be adopted to meet various engineering needs and user requirements.
The valve body has a complete range of materials, and the packing and gasket can be reasonably selected according to actual working conditions or user requirements, and can be applied to various pressure, temperature and medium working conditions.
The inverted seal is made of threaded sealing seat or body surfacing of austenitic stainless steel. The sealing is reliable and the packing can be replaced without stopping the machine. It is convenient and fast and does not affect the operation of the system.
, Equipped with a series of multi-turn electric devices, which have small shells, light weight, and full functions. They can be used with remote computers, and electric devices can also be selected according to user requirements.
