JH Double Eccentric Butterfly Valve – DN50 to DN1800, CL150–600, Fire-Safe Design

The JH Double Eccentric Butterfly Valve is engineered for superior performance in medium- to high-pressure flow control applications. Utilizing a double-offset disc design, the valve disc moves away from the seat upon opening, significantly reducing friction, minimizing wear, and extending service life. This geometry enhances sealing performance and makes the valve especially suitable for throttling as well as on/off applications.

Designed with safety and compactness in mind, the valve features a fire-safe structure, blowout-proof stem, and compact construction for limited-space installations. Its robust sealing performance and mechanical reliability make it well-suited for demanding service conditions across water treatment, power, chemical, oil & gas, and HVAC systems.
