Butterfly Valve – China Manufacturer & Supplier

Premium Quality Butterfly Valves from China

As a professional China butterfly valve manufacturer, Yuanjd Valve specializes in the design, production, and supply of high-performance butterfly valves for a wide range of industrial applications. Our butterfly valves are engineered to provide reliable flow control and shut-off performance in water treatment, oil and gas, chemical processing, power generation, and HVAC systems.

Butterfly valves operate by rotating a built-in disc by 90 degrees to start, stop, or regulate flow. This simple yet effective design offers significant advantages over traditional gate and ball valves: butterfly valves are lightweight, compact, corrosion-resistant, and can withstand extreme temperatures. In fact, a 24-inch butterfly valve weighs roughly one-tenth of an equivalent gate valve and costs a fraction of a ball valve—an advantage that grows with pipe size. For applications requiring fast isolation and flow modulation, butterfly valves are the superior choice.

Manufactured in strict accordance with API 609, EN 593, AWWA C504, and ISO 5752 standards, our butterfly valves are available in wafer, lug, and double-flanged body styles. Size ranges cover DN50 to DN2200 (NPS 2″ to 88″), with pressure ratings up to PN40 and temperature ranges from -40°C to +800°C depending on seat material selection.
