Explore our premium selection of Triple Offset and high-performance valves engineered for excellence.
Advanced engineering for zero-leakage in the world's most demanding environments.
The Triple Offset Butterfly Valve (TOBV) is not just a valve; it is a masterclass in geometric optimization. Unlike traditional concentric or double-eccentric valves, the triple offset design introduces a third "angular" eccentricity. This geometry ensures that the disc only contacts the seat at the final point of closure.
This "cam-action" sealing eliminates friction between the seal and the seat, which is the primary cause of valve failure in high-cycle applications. As a leading Custom Triple Offset Butterfly Valve Supplier, we utilize advanced CFD (Computational Fluid Dynamics) to refine these offsets, providing bi-directional zero-leakage performance even in extreme cryogenic or high-heat conditions.

When searching for a Triple Offset Butterfly Valve Factory, global enterprises prioritize three things: 1) Quality Consistency, 2) Cost Efficiency, and 3) Engineering Agility. KR Valve Group leverages China’s massive industrial infrastructure to offer superior value:
Modern procurement isn't just about buying a part; it's about compliance and reliability. We understand that a valve in a Brazilian sewage plant faces different regulatory and environmental challenges than one in an Italian waterworks.
Our products adhere to international certifications including ISO 9001, API 609 (the gold standard for TOBV), and CE/PED for the European market. By providing comprehensive documentation (MTRs, Pressure Test Reports, Fire-Safe Certificates), we ensure that your local inspectors and engineers have full confidence in our hardware.
Leveraging technology and experience to deliver unmatched performance.
Continuous innovation ensuring our technicians develop valves that meet the evolving requirements of the global market.
"Zero Leakage" is our principle. Every valve undergoes pressure and seat tightness testing before dispatch.
Providing bespoke branding and non-standard engineering solutions for world-renowned valve brands.
Utilizing high-grade SS304, SS316, and specialized alloys for maximum corrosion resistance and durability.
Proven track record in exporting to 50+ regions including Europe, Asia, Africa, and Oceania.
A professional 24H rapid response team to assist with installation, maintenance, and technical queries.
The industry is moving toward Digitalization and Sustainability. At KR Valve, we are integrating smart actuators and positioners that allow for predictive maintenance. This reduces downtime in critical sectors like Oil & Gas and Power Generation. Furthermore, the push for "Low-Emission" valves is driving the demand for our high-integrity stem sealing designs, which prevent fugitive emissions—a key requirement for modern ESG (Environmental, Social, and Governance) compliance.
Our valves are currently operational in various high-stakes scenarios:
The third offset—the cone-shaped sealing geometry—completely eliminates friction throughout the entire stroke. A double offset valve still experiences some seat friction during the first few degrees of opening, whereas the triple offset only contacts the seat at the point of final closure. This significantly extends service life and ensures a bubble-tight seal.
Yes. Due to their metal-to-metal seating and WCB or Stainless Steel construction, TOBVs are excellent for high-temperature steam. They handle thermal expansion much better than resilient-seated valves.
Every custom project begins with a technical review by our R&D team. We provide 100% inspection, including hydrostatic and air testing, and can facilitate third-party inspections (SGS, BV) upon request.
While it depends on the size and material, our standard lead time is 4-6 weeks, significantly shorter than the industry average, thanks to our monthly inventory updates and in-house machining.
From PTFE lined solutions to heavy-duty check valves, we cover all pipeline requirements.
Over 20 years of engineering excellence, supporting the world's vital infrastructure.
KR Valve Group has more than 20 years of experience in producing standard and non-standard valves. We supply over 500 valve products, including butterfly valves, gate valves, check valves, and water control valves. These are utilized in water treatment, dam construction, energy, and chemical engineering. Our repeat purchase rate is a testament to our quality.
We believe reliable service is as crucial as superior products. Today, KR products are exported to over 50 countries across Europe, Asia, and Africa. We leverage our expertise and unwavering commitment to quality to support your success. From raw materials to finished products, each process is strictly inspected to ensure timely delivery and efficient performance.
