Global Commercial LandscapeIn the era of Industry 4.0, the global demand for automated flow control has surged by 15% annually. Pneumatic Lug Butterfly Valves represent the pinnacle of this shift, offering a reliable, lightweight alternative to traditional gate valves in complex piping networks. As a leading manufacturer, we provide the backbone for large-scale infrastructure projects across Europe, SE Asia, and the Americas.
Technical ExcellenceOur Lug-style design utilizes threaded inserts on both sides of the valve body. This allows for dead-end service or the removal of downstream piping without affecting the upstream system. Integrated with high-torque pneumatic actuators, our valves ensure millisecond response times and zero-leakage performance under PN10/PN16/PN25 pressures.
Compliance & E-E-A-TWith over 20 years of manufacturing experience, KR Valve adheres to rigorous international standards including API 609, ISO 5211 (actuator mounting), and CE/PED certifications. Our expertise isn't just in casting iron; it's in the engineering precision that prevents costly industrial downtime.
The transition from manual to pneumatic operation is not merely a convenience—it is a requirement for modern safety protocols. Automatic "Fail-Safe" features, enabled by single-acting spring-return actuators, ensure that in the event of air loss, the valve returns to a safe position (Open or Closed). This is critical in chemical processing and volatile liquid transport. Our factory utilizes high-grade aluminum alloy for actuator housings, treated with hard anodization to resist corrosive environments.
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, providing project construction and brand marketing services to thousands of customers.
