H61H/Y Power Station Check ValveDetailed product description：

Product Usage
The two ends of the branch pipe are welded structures, and the welding groove can be made according to standards or user requirements. It is suitable for use as a device to prevent medium backflow on pipelines of high temperature and high pressure water, steam, oil, and superheated steam in thermal power plants, petrochemicals, metallurgy, and other industries.

Product Structure Features:

One is the imported type that follows the ANSI B16.34 and JIS E101 standards; Another type is the national standard version of Jb3595 standard. The temperature and pressure levels it follows are consistent, and there is a certain exchange relationship in some pipelines. The central part adopts a pressure self tightening type without valve cover, which has good sealing performance under high temperature and high pressure conditions. There are two types of materials for self sealing rings: one is low-carbon steel, and the other is flexible graphite clamp 316 wire (mesh). Sealing surface welding with drilling based hard alloy. The processed pure metal layer is ≥ 3mm, with wear resistance, high temperature resistance, corrosion resistance, abrasion resistance, and long service life.
