Product Usage
Flange globe valve is applicable to the nominal presssure PN1.6~16.0Mpa, working degree -46~550℃ oil, chemical pharmaceutical, fertilizer, power industry and other working conditions on the pipeline, cut off or connected to the pipeline medium.
Product Features
Rational structure, reliable sealing, excallent performance, pretty appearance;
Co-radix alloy weled sealing surface，anti-wearing, erosion-proof abrasion-proof and longer use life.
The surface and the adjusting media of the valve shaft are nitrogenized so that it is erosion and abrasion resistant
There is backward sealing structure in the valve, so the sealing is reliable;
The material of the fillings and the flange sizes can be chose and mached according to the applications and the requirements of the users. That can satisfies all kinds of working requirements.
