J941H/J941Y Electric Medium Pressure Flange Globe Valve

The J941H/J941Y electric medium pressure flange globe valve consists of a carbon steel medium pressure globe valve and a Z-type multi turn electric actuator, with different sealing surfaces selected for different working conditions. There are two types: switch type and adjustable type, with a working voltage of generally 380VAC. Other voltages can be customized if needed. Electric globe valves are suitable for cutting off or connecting pipeline media in various working conditions such as petroleum, chemical, pharmaceutical, fertilizer, and power industries with a nominal pressure of PN1.6~16MPa and a working temperature of -29~550 ℃. The driving methods include manual, gear transmission, electric, pneumatic, etc.

Product structure features:

Carefully selected materials, in compliance with relevant domestic and international standards, with a reasonable structure and beautiful appearance.
The sealing surfaces of the valve disc and valve seat are made of iron-based alloy overlay welding or Stellite cobalt based hard alloy overlay welding, which has good wear resistance, high temperature resistance, corrosion resistance, scratch resistance, and long service life.
The valve stem has undergone quenching and surface nitriding treatment, which has good corrosion resistance and scratch resistance.
Various piping flange standards and flange sealing surface types can be used to meet various engineering needs and user requirements.
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.
The reverse seal is made by connecting the sealing seat with threads or welding austenitic stainless steel on the body, which is reliable in sealing. The replacement of fillers can be carried out without stopping the machine, which is convenient and fast, and does not affect the operation of the system.
Equipped with the DZW series multi turn electric device, it has a small shell, light weight, full functionality, and can be used with remote computers. Electric devices can also be selected according to user requirements.
