What Is a Soft Seated Butterfly Valve?
A soft seated butterfly valve is a quarter-turn valve designed with a resilient seat made from materials such as EPDM, NBR, or PTFE. The resilient seat provides reliable shut-off between the disc and seat, making the valve suitable for water, HVAC, utility, and general service applications.
Compared with metal seated butterfly valves, soft seated designs are generally preferred for standard operating conditions where bubble-tight sealing, low operating torque, and economical installation are important.
Soft seated butterfly valves are widely used in water treatment, chilled water systems, cooling water lines, utility piping, and selected mildly corrosive media because they offer dependable sealing and practical operating performance.
