Butterfly Valve Suppliers & Manufacturers in China
Butterfly Valve · 371 products · page 8/21
Butterfly valves control flow with a rotating disc mounted on a shaft, which keeps them compact, lightweight and inexpensive compared with gate or ball valves of the same bore. That makes them common in water treatment, HVAC, fire protection, food processing and general industrial lines where space and weight matter. The trade-offs are seat and disc material, pressure rating and the ability to throttle: a resilient seat gives tight shut-off at lower temperatures, while a metal seat suits higher temperatures and abrasive media.
Buyers comparing butterfly valve suppliers in China should check the body style (wafer, lugged, double-flanged), the actuator (lever, gearbox, electric or pneumatic), the liner material (EPDM, NBR, PTFE) and whether the valve is designed for dead-end service. Size range, face-to-face standard and pressure test reports are the details that decide whether a unit fits an existing pipeline.
