The global industrial landscape is undergoing a paradigm shift, transitioning from simple mechanical actuation to complex, automated "Smart Flow" systems. Custom hydraulic control butterfly valves represent the pinnacle of this evolution. Unlike standard manual or pneumatic valves, hydraulic actuation provides the necessary torque and precision required for large-diameter pipelines (up to DN3000) and high-pressure environments common in modern hydroelectric dams and municipal water networks.
Industry 4.0 has integrated digital twins and IoT sensors into hydraulic actuators, allowing for real-time monitoring of valve position, fluid velocity, and pressure drops. As an experienced growth director in the SEO space, we recognize that "User Intent" for these products has moved beyond mere price comparison to a deep search for technical reliability, maintenance-free lifecycles, and certification compliance (ISO, CE, API).
Hydraulic systems offer much higher power-to-weight ratios than electric motors, essential for rapid shut-off in emergency conditions.
Advanced hydraulic controllers allow for infinite positioning, ensuring zero water hammer effect during valve transition.
Equipped with accumulator systems, these valves can operate even during total power failure, protecting critical infrastructure.
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. We has won high repeat purchase rates from customers with excellent product variety and quality.
Beyond product excellence, we are dedicated to creating a mutually beneficial partnership with every customer. Today, KR VALVE’s products have been exported to over 50 countries and regions in Europe, Asia, Africa, and Oceania, providing project construction and brand marketing services to thousands of customers.
Modern procurement directors are no longer just looking for the lowest cost; they are looking for "Value-Add" and "Information Gain." China's valve manufacturing sector has transitioned into the 4.0 era, where KR Valve leads with automated machining centers and 100% digitalized inspection protocols. Our Custom hydraulic cylinder butterfly valves (Double Eccentric Type) are manufactured under strict ISO-9001 quality management, ensuring that every micron of the sealing surface meets international standards.
The efficiency of the Chinese supply chain allows us to provide OEM/ODM services with shorter lead times than European counterparts, without compromising on the material integrity of components like SS304 discs, EPDM seats, or WCB bodies. This resilience is critical for global projects where a delay in a single valve can stall a multi-billion dollar dam or chemical plant project.
Our R&D technicians continuously develop products that meet market requirements, using modern testing labs to elevate performance.
With over 30 sets of advanced production equipment, we execute monthly inventory updates to ensure timely delivery.
Zero leakage is our principle. We conduct rigorous pressure and appearance tests according to international standards.
Choosing the right butterfly valve requires understanding the semantics of "Sealing Mechanics." For standard water treatment, a Concentric Resilient Seated valve is often sufficient. However, for hydraulic control applications involving high-frequency cycles or high temperatures, the Double Eccentric or Triple Offset design is superior.
The double eccentric design offsets the shaft from the center of the disc and the center of the body. This creates a cam action that lifts the disc off the seat immediately upon opening, drastically reducing friction and extending the life of the EPDM or PTFE seal. When paired with a hydraulic cylinder, this design allows for the smooth handling of "Big Size" valves (DN200-DN3000) that would otherwise require massive amounts of energy to operate.

Chile Dam Project: Hydraulic control valve integration for power generation.
Indonesia Sludge Plant: Corrosion-resistant butterfly and gate valves.
Russia Gas Project: High-pressure WCB gate valves and ball valves.
A: Hydraulic control offers faster response times and significantly higher torque for large-bore valves. It is also safer in explosive environments (ATEX) as it doesn't require high-voltage electricity at the valve site.
A: For high corrosion resistance, we recommend Ductile Iron (GGG40/50) with an EPDM seal or CF8 (SS304) stainless steel components. For chemical applications, PTFE seats provide the best chemical inertness.
A: Every valve undergoes a 1.5x working pressure shell test and a 1.1x pressure seat test according to API 598 or EN 12266 standards before leaving our factory.
A: Yes, we specialize in both international standards (ANSI, DIN, JIS, BS) and non-standard custom dimensions to fit existing legacy pipelines.
