Product Overview
Stainless steel check valve (H42H cast steel vertical check valve) is a valve whose disc slides along the center line of the valve body. Pipeline vertical check valve is a new type of valve with the characteristics of simple structure, few parts, light weight, good processability, and is one of the development directions of check valves. However, the fluid resistance coefficient is slightly larger than that of the swing check valve. H42H can be equipped with springs or without springs according to the vertical or horizontal installation conditions.
Performance characteristics
1. Three-dimensional check valves are divided into flange and wafer, with simple structure, few parts, and light weight. Vertical check valves are mainly used in various working conditions where medium backflow needs to be prevented.
2. When the vertical check valve is used for vertical installation, no spring is required, and the weight of the valve disc itself and the pressure of the fluid backflow are used to check the valve.
Application field
Vertical check valves are widely used in various pipelines where medium backflow needs to be prevented, such as petroleum, chemical, pharmaceutical, and power industries.
