J41H
显沃科技
Models: J41H, J41T1-T8, J41W, J41Y, etc.
Caliber: DN15 ～ DN200
Pressure: PN16 ～ PN160
Material: carbon steel, stainless steel, alloy steel, duplex steel
Drive: manual, gear transmission, electric, pneumatic
Applications: Petroleum, chemical, natural gas, petrochemical, coal chemical and other industries
The national standard cut-off valve is suitable for various pipelines from DN15 to DN200 and PN16 to PN160, used to cut off or connect the medium in the pipeline. With different materials selected, Xianwo Technology's national standard globe valve can be applied to various media such as water, steam, oil, nitric acid, acetic acid, oxidizing media, urea, etc. The drive method of the national standard globe valve is manual, gear transmission, pneumatic or electric. The national standard globe valve is generally flanged or butt welded.
The body and cover of the national standard globe valve developed and produced by Xianwo are generally connected by studs + nuts. The middle flange gasket adopts stainless steel + flexible graphite spiral gasket or metal ring gasket. According to user needs, flexible graphite forming filler, PTFE, flexible graphite forming filler with various metal wires or composite filler can be selected. A pad spring-loaded packing compression mechanism can be used. With upper sealing structure, auxiliary sealing. The valve seat adopts forged valve seat and stainless steel valve seat, and the sealing surface is welded with the alloy specified by the user. The valve stem adopts integral forging structure. The stem nut is generally made of ASTM A439 D2 or copper alloy material.
Design and manufacturing standards: GB / T 12235, JB / T 7746
Structural length standard: GB / T 12221
Connection flange standard: GB / T 9112 ～ 9124, JB / T 74 ～ 90, HG / T 20592
Test and inspection standards: GB / T 13927, GB / T 26480, JB / T9092, ISO 5208
