H64Y American Standard Power Station Check Valve

H64Y American Standard Power Station Check Valve Structure
H64Y American Standard Power Station Check Valve Structure

Scope of application

H64Y American standard power station check valve branch pipe is welded at both ends. The welded bevel can be made according to standards or user requirements. It is suitable for Class 1500 ~ 2500Lb, working temperature -29 ~ 570 ℃ for petroleum, chemical and thermal power stations Working conditions on the pipeline. Applicable medium: water, oil, steam, etc.

Structural features

One is the introduction type following the ANSIB16.34 and JIS E101 standards; the other is the national standard type of the Jb3595 standard. It follows the same temperature and pressure levels, and there is some kind of interchange relationship in some pipelines. The middle part adopts non-bond pressure self-tightening type, which has good sealing performance under high temperature and high pressure conditions. There are two materials for self-sealing ring: one is low carbon steel, and the other is flexible graphite clamp 316 wire (net). Seal surface surfacing drill-based cemented carbide. The processed pure metal layer is ≥3mm, which has abrasion resistance, high temperature resistance, corrosion resistance, abrasion resistance and long service life.
