Reliable Zero-Leakage Performance for Industrial Fluid Control
The Kunjian Soft Seal Butterfly Valve is designed for high-efficiency flow regulation and bubble-tight shut-off in low to medium-pressure systems. Engineered for B2B applications, this valve uses premium elastomer seats (EPDM, NBR, or PTFE) to ensure a perfect seal and long-term durability in utility and industrial environments.
Key Technical Features
- The resilient-seated design provides 100% bi-directional tight shut-off, preventing leakage even in sensitive systems.
- Optimized disc-to-seat friction reduces the force required for actuation, extending the life of manual levers or automated actuators.
- Built with ductile iron, stainless steel, or WCB bodies and specialized coatings to withstand harsh industrial conditions.
- Available in Wafer, Lug, and Flanged body styles to meet international piping standards (ANSI, DIN, JIS).
- A simple, lightweight structure allows for fast installation and on-site seat replacement, minimizing your operational downtime.
Primary Applications
Our soft-seated valves are ideal for Water Treatment, HVAC Systems, Chemical Processing, and Food & Beverage industries.
