vertical check valve
Other Products
I. Introduction:
The H42H vertical check valve is designed and manufactured strictly in accordance with API 6D and GB/T 12235 standards. This series of valves is normally in the closed state. Driven by the pressure of the medium at the inlet end of the pipeline, it overcomes the spring resistance to open the valve. When the pressure of the medium at the inlet end is lower than that at the outlet end, the spring pushes the disc against the valve seat to close the valve and prevent medium backflow, thus functioning as a check valve. Since this valve uses a spring to support the disc, it can be installed either vertically or horizontally. This product is widely used in pipelines of various working conditions in industries such as petroleum, chemical, pharmaceutical, and power. The vertical check valve is a vertical flanged check valve that uses a spring to support the disc, so it can be installed either vertically or horizontally. This check valve is widely used in pipelines of various working conditions in industries such as petroleum, chemical, pharmaceutical, and power.
II. Features:
1. The disc has a short stroke and high sensitivity, which greatly reduces the time required for the disc to close and effectively lowers the water hammer pressure of the check valve.
2. The sealing surface is made of alloy steel or hard alloy, with a reasonable matching of sealing pair materials, ensuring a long service life.
