Description & Features

Due to their ability to resist corrosion,duplex alloy checkvalves made of super duplex are often quite useful in various industrial processes including seawater systems and desalination plants. These corrosion-resistant valves are extremely functional in marine conditions such as subsea, offshore, and platform work. Also, these severe service valves are perfect in the chemical industry.

● Horizontal or vertical pipe can be used, easy installation.

● Smooth flow channel, fluid resistance is small.

● The open-close part is control by medium itself to prevent backflow.

● The valve flow is streamlined, low resistance.
