In the modern fluid control landscape, the Eccentric Butterfly Valve has emerged as a critical component for high-pressure and high-temperature environments. Unlike traditional concentric valves, eccentric designs utilize an offset shaft that reduces friction during the opening and closing cycles. As a premier Custom Eccentric Butterfly Valve Manufacturer, KR Valve specializes in double and triple offset engineering, ensuring zero-leakage performance across critical infrastructure projects.
The "Eccentricity" refers to the displacement of the stem from the center of the valve body and disc. This allows the disc to "cam" into the seat, significantly reducing wear and extending the operational lifespan of the valve, even in abrasive media or high-cycle applications.
Designed for severe service conditions, our eccentric valves handle extreme pressures and temperatures that standard valves cannot tolerate.
Utilizing SS304 surfacing and laminated seals, we achieve bi-directional bubble-tight shutoff compliant with API 598 standards.
The offset design significantly reduces the torque required to operate the valve, allowing for smaller, more cost-effective actuators.
KR has more than 20 years of experience in producing standard and non-standard valves of various types. We supply a wide selection of over 500 valve products, including butterfly valve, gate valve, check valve, water control valve, as well as all their matching and accessory products. These products have applications in various industries such as water treatment, dam construction, commercial buildings, energy and heating, chemical engineering, etc.
Today, KR VALVE’s products have been exported to over 50 countries and regions in Europe, Asia, Africa, and Oceania. We believe that reliable service is as crucial as superior products, and we strive to continuously optimize the customer experience to achieve long-term win-win cooperation.
China has become the global hub for high-precision valve manufacturing. Sourcing from a specialized China Valve Factory like KR Valve offers unique competitive advantages that go beyond cost savings. It is about the synergy of advanced metallurgy, specialized supply chains, and rapid prototyping capabilities.
Direct access to high-grade GGG40, WCB, and Stainless Steel foundries ensures material integrity and traceability (EN 10204 3.1).
Our R&D department can modify face-to-face dimensions, flange drillings (ANSI, DIN, JIS), and coating specs within days, not weeks.
With 15+ advanced machining centers, we maintain tolerances up to 0.01mm, crucial for the seating of double eccentric valves.
Located near major ports, we offer streamlined global shipping, reducing lead times for international infrastructure projects.
