Unlike standard butterfly valves, the Triple Offset Wafer Butterfly Valve utilizes three distinct offsets to eliminate friction between the seat and the seal ring. The third offset—the conical geometry of the sealing components—enables torque-seated sealing, ensuring zero-leakage even in high-pressure steam and cryogenic applications.
Our manufacturing process adheres to API 609 and ASME B16.34 standards. We utilize premium WCB, CF8M, and Duplex Steel bodies with Stellite® hard-faced seats. This metallurgical excellence ensures resistance against cavitation, erosion, and thermal cycling, which is critical for long-term reliability in harsh environments.
As the world pivots toward Industry 4.0 and Decarbonization, the demand for "Fugitive Emission" compliant valves (ISO 15848-1) has skyrocketed. Our custom TOV designs are currently supporting hydrogen transport, Carbon Capture (CCUS), and LNG infrastructure across Europe, North America, and the Middle East.
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.
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.
Our Triple Offset valves provide bubble-tight shut-off for high-temperature steam lines. The wafer design minimizes the face-to-face dimension, allowing for compact piping layouts in urban heating plants and geothermal facilities.
Using Nickel-Aluminum Bronze or Super Duplex materials, our valves withstand the corrosive nature of seawater. The triple eccentric design ensures that the seal remains intact even after thousands of cycles in high-salinity conditions.
Optimized for fire-safe performance (API 607), these valves are essential for tank farms and pipeline manifold systems where space is at a premium but safety cannot be compromised.
The next decade of valve manufacturing is defined by Smart Integration. KR Valve is currently investing in three core areas:
A: The wafer design is significantly lighter and more cost-effective. It fits between existing pipeline flanges, making it ideal for retrofitting projects where space and weight limitations exist, such as on offshore platforms or shipboard systems.
A: Unlike resilient-seated valves, metal seats can withstand temperatures up to 600°C and are inherently fire-safe. The triple offset geometry ensures the metal seal ring contacts the seat only at the final point of closure, preventing wear.
A: We provide documentation for regional standards including CE/PED for Europe, EAC for Russia, and CRN for Canada. Our inspection department conducts 100% pressure testing according to API 598 before shipment.
R&D department to ensure product design and continuous innovation. Our technicians develop products that meet market requirements with 20 series and over 500 varieties.
Manufactured under ISO-9001 quality management. We have over 30 production equipment units and update inventory monthly to ensure timely delivery.
Zero leakage is our principle. We conduct a series of inspections on appearance, size, and pressure in compliance with international standards.
