Product Overview:

The stainless steel vertical check valve is a valve where the disc slides along the centerline of the valve body. The pipeline vertical check valve is a newly developed type of valve, featuring simple structure, few components, lightweight, and good manufacturability, making it one of the development directions for check valves. However, its fluid resistance coefficient is slightly higher than that of swing check valves. Vertical check valves are widely used in petroleum, chemical, pharmaceutical, power, and other industries where backflow prevention is required. The H42H model can be equipped with or without a spring depending on vertical or horizontal installation conditions.

1. Vertical check valves come in flanged and wafer types, featuring simple structure, few components, and lightweight. They are primarily used in applications requiring prevention of medium backflow.

2. For vertical installation, the vertical check valve may not require a spring, as it relies on the disc's own weight and the pressure of the reverse flow to function as a check valve.

Stainless Steel Vertical Check Valve H42H Working Principle:

The H42H series vertical check valve prevents medium backflow, serving as a check valve. It remains open when the inlet pressure exceeds the outlet pressure. Under the inlet medium pressure, the disc is pushed open, allowing the valve to open automatically. When the inlet pressure is lower than the outlet pressure, the spring pushes the disc against the seat to close the valve (Note: Horizontal installation requires a spring, while vertical pipeline installation does not. The disc closes automatically under its own weight and the pressure of the reverse flow medium).
