Z44H 4A duplex stainless steel check valve, duplex stainless steel check valve

Product Introduction

The 2205 duplex steel check valve is designed to prevent the backflow of the medium in the pipeline. The opening and closing components operate automatically based on the flow of the medium and external force to prevent the backflow of the medium. Such a valve is called a check valve. Check valves belong to automatic valves and are mainly used in pipelines where the medium flows in a single direction. They allow the medium to flow in only one direction to prevent accidents. This type of valve is generally installed horizontally in the pipeline. The duplex steel check valve is particularly suitable for applications involving chlorine-containing water solutions, slightly salty water solutions, diluted sulfuric acid solutions, pure organic acids and their mixtures, petroleum and natural gas, crude oil from refineries, sulfur-containing gases, and wastewater treatment.
