In the modern industrial landscape, Gear Operated Butterfly Valves (GOBV) serve as the critical interface between automated precision and manual reliability. As global urbanization accelerates, the demand for robust water distribution and wastewater treatment facilities has skyrocketed. These valves are essential for handling high-pressure flows (PN16/PN25) where manual lever operation becomes physically impossible due to torque requirements.
Within power generation and district heating circuits, Gear-driven systems ensure that large-bore valves (up to DN1200 and beyond) can be modulated with minimal operator fatigue. By utilizing worm-gear mechanisms, these valves provide self-locking capabilities, preventing "water hammer" effects caused by sudden disc movement under high velocity.
The transition toward sustainable manufacturing requires valves that minimize fugitive emissions. Our RPTFE and EPDM soft-seal technologies comply with stringent international environmental standards, ensuring zero-leakage performance in chemical processing and desalination plants.
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 have won high repeat purchase rates from customers with excellent product variety and quality.
Our technicians continuously develop products meeting market requirements. Our lab provides modern testing to elevate performance. We currently offer 20 series and 500 varieties.
Manufactured under ISO-9001 supervision. We have over 30 sets of production equipment and update inventory monthly to ensure timely delivery.
Zero leakage is our principle. We conduct rigorous inspections on appearance, size, and pressure according to international standards.
Today's focus is on high-ratio worm gearboxes that allow fine-tuned flow control. Materials like Ductile Iron (GGG40/50) and Stainless Steel (SS304/316) discs provide the backbone for reliable service life in corrosive environments.
We are integrating digital position indicators and IoT-ready sensors into our gearbox designs. This allows facility managers to monitor valve position and torque profiles remotely, predicting maintenance needs before failures occur.
Our R&D is currently testing advanced polymer composites for RPTFE seals to extend lifecycle limits beyond 50,000 cycles in high-temperature industrial steam and chemical applications.
Supplied various water control valves for large-scale hydraulic management, ensuring safety in extreme pressure conditions.
Integrated big-size Gear Operated Butterfly Valves and Check Valves to stabilize the urban water supply network.
Heavy-duty butterfly and gate valves customized for high-viscosity fluid handling in environmental remediation.
We understand that every region has unique regulatory requirements. Our products are engineered to exceed local standards including:
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, providing project construction and brand marketing services to thousands of customers.
