H61Y High Pressure Lift Power Station Check Valve Overview:

H61Y High Pressure Lift Power Station Check Valve produced and sold by Baigang valve group branch pipe ends welded structure, welded groove can be produced according to the standard or user requirements, suitable for thermal power plant, petrochemical, metallurgy and other high temperature and pressure water, steam, oil, superheated steam pipe Prevent medium reflux on the device. One is to follow the introduction of ANSIB16.34 and JIS E101 standards; the other is Jb3595 standard GB. The temperature and pressure levels it follows are consistent, and some pipelines have some sort of interchange relationship. In the middle, the valve cover pressure is self-tight, which has good sealing performance under high temperature and high pressure conditions. Self-sealing ring has two kinds of materials: one is low-carbon steel, the other is flexible graphite folder 316 wire (net). Sealing surface surfacing drilling based hardmetal. The processed pure metal layer ≥ 3mm, with wear resistance, high temperature, corrosion resistance, abrasion resistance, long service life.

H61Y High Pressure Lift Power Station Check Valve performance specifications:

H61Y High Pressure Lift Power Station Check Valve structure Features:

1, the overall valve quenching, and can move up and down in the body, the media backwards, by media pressure and the spring valve automatically closed.

2, the valve body, valve cover are forgings.

3, the sealing surface of the valve seat using cobalt-based carbide plasma spray welding surface into. Wear-resistant, anti-abrasion performance.

4, check valve should be installed on the level of pipeline media flow from the bottom up (positive flow).
