In the complex landscape of industrial flow control, selecting between Lug Type and Wafer Type butterfly valves is more than a technicality—it is a critical decision impacting system safety, maintenance efficiency, and lifecycle costs. As a leading manufacturer with over 20 years of expertise, KR (KR VALVE GROUP) provides high-performance solutions tailored to the rigorous demands of water treatment, chemical engineering, and energy sectors.
Understanding the Search Intent of engineers often boils down to application-specific constraints:
Years of Valve Manufacturing Expertise
Product Variations in Catalog
Countries Exported Worldwide
Leakage Principle Tolerance
Our R&D department ensures continuous innovation. Our lab provides extensive modern testing capabilities to elevate product performance. We currently hold 20 series of products meeting global standards like API, DIN, and BS.
With over 30 sets of advanced production equipment, we follow strict ISO-9001 quality management systems. Each valve is manufactured under rigorous supervision to meet monthly inventory updates and ensure timely delivery.
"Zero leakage" is our core principle. We conduct a series of inspections on appearance, dimensions, and pressure testing in compliance with international standards, providing full traceability for every batch.
Procuring from a specialized China-based manufacturer like KR offers significant Information Gain for global buyers. We leverage a vertically integrated supply chain that reduces lead times and ensures competitive pricing without compromising on material integrity.
Access to premium GGG40, WCB, and Stainless Steel alloys directly from verified foundries.
Full flexibility in disc materials (CF8, CF8M) and seat options (EPDM, PTFE, NBR) for specific media.
Proximity to major ports (Ningbo/Shanghai) ensures rapid global distribution to Europe, Asia, and Africa.
Ability to handle both high-volume municipal projects and specialized low-volume custom orders.
Industrial valves must adhere to local regulations to ensure safety and environmental protection. At KR, we provide localized support for various international standards:
Standards: WRAS, NSF/ANSI 61.
Context: Used in Italy and Brazil for massive sewage treatment and dam projects where EPDM soft seals provide reliable isolation.
Standards: API 609, Fire-Safe Testing.
Context: Triple eccentric butterfly valves provided to natural gas projects in Russia, ensuring zero-leakage in high-pressure gas pipelines.
Standards: CE/PED, ISO 15848-1.
Context: Corrosion-resistant valves (PTFE lined) supplied to chemical plants in Vietnam to handle aggressive media.
The valve industry is moving towards Smart Flow Control. KR is at the forefront, integrating pneumatic and electric actuators with IoT capabilities for remote monitoring. Sustainability is also key—our renewable metal seat designs extend the valve's lifecycle, reducing the total carbon footprint of industrial installations.
