Resilient seated butterfly valves are the backbone of modern piping systems. Unlike metal-seated valves, they utilize flexible elastomeric materials (EPDM, NBR, Viton) to achieve a bubble-tight shut-off. Our manufacturing process integrates advanced vulcanization technology, ensuring the seat remains bonded to the body or disc even under high-velocity flow, reducing torque and extending life cycles beyond 50,000 operations.
As a leading China factory, KR Valve leverages the world's most robust industrial supply chain. We provide information gain by controlling the entire metallurgical process—from the ductile iron (GGG40/50) casting to the precision CNC machining of the valve stem and disc. This vertical integration allows us to offer OEM services with superior cost-to-quality ratios that European or American competitors cannot match.
Large-scale engineering projects require more than just a product; they require compliance and reliability. Our valves meet international standards including API 609, DIN 3202, and BS 5155. For global procurement officers, we provide full traceability reports, material certifications, and 100% pressure testing evidence to ensure zero-risk integration into municipal or industrial networks.
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. We believe that reliable service is as crucial as superior products, and we strive to continuously optimize the customer experience to achieve long-term win-win cooperation. Today, KR VALVE’s products have been exported to over 50 countries and regions in Europe, Asia, Africa, and Oceania.
Types of Valve Products
Exporting Countries
Integration of smart sensors for real-time monitoring of valve position, pressure, and leakage detection in "Smart City" water networks.
Emergence of high-performance EPDM and PTFE composites that withstand higher temperatures and aggressive chemical pH levels.
Low-torque designs that allow for smaller, more efficient actuators, reducing the carbon footprint of industrial plants.
Growing demand for bespoke valve face-to-face dimensions to replace legacy infrastructure without repiping.
Our resilient seated butterfly valves are primary choices for desalination plants and municipal sewage systems. The EPDM seat provides excellent resistance to the biological growth and chemicals found in wastewater treatment. For high-rise commercial buildings, our PN16/PN25 rated valves ensure reliable pressure regulation and backflow prevention.
In cooling water circuits of power plants, concentric butterfly valves offer the perfect balance of flow control and economy. The lightweight wafer design allows for rapid installation in tight spaces, while the resilient seat compensates for minor pipe misalignments caused by thermal expansion.
Corrosion is the enemy of industrial longevity. KR Valve's PTFE-lined and Stainless Steel disc options (CF8/CF8M) provide a barrier against aggressive media. Our triple eccentric structures are utilized where high-pressure steam or volatile chemicals require a metal-to-metal backup with resilient sealing properties.
Large-scale irrigation projects require durable, low-maintenance valves. Our ductile iron valves with epoxy coating (250μm+) resist external environmental corrosion and internal abrasive wear from silt-laden water.
We have our own independent brand ‘KR’ and also provide OEM services to our customers, we have established long-term relationship with many famous brand.
We have 15 machining machines and assembly line, and our workers are all experienced in precision valve assembly.
Inspection department to ensure 100% inspection quality of products. Zero leakage is our principle. According to international standards, we conduct appearance, size, and pressure tests.
Supplied various water control valves to a massive municipal sewage project, ensuring environmental safety and flow efficiency.
Heavy-duty water control valves provided for high-pressure hydraulic regulation in national infrastructure.
Big size butterfly valves and check valves integrated into Italian municipal water distribution networks.
