Introduction to SDNR Valve
SDNR (Soft Seated Double Offset Butterfly Resilient Seated) valves are a type of high - performance butterfly valves. They are designed with a double - offset disc and a soft seat, which offers several advantages. The double - offset design reduces friction between the disc and the seat during valve operation, resulting in a longer service life. The soft seat provides a tight seal, preventing leakage, and is suitable for a wide range of applications, including water supply, wastewater treatment, chemical processing, and HVAC systems. These valves can handle different pressure and temperature ranges, and their relatively simple structure makes installation and maintenance straightforward.
