In the modern industrial landscape, a valve with flow control is no longer a simple mechanical obstruction. It is a sophisticated instrument of process optimization. As a premier OEM valve manufacturer, KR has spent over 20 years mastering the nuances of fluid velocity, pressure drops, and cavitation prevention. The global industrial sector, ranging from desalination plants in Chile to chemical processing hubs in Vietnam, demands valves that offer not just "on/off" functionality, but granular modulation.
Standard and custom valve types engineered for high-performance environments.
Countries supported with localized technical documentation and compliance.
Leak-proof testing protocol ensuring zero-leakage reliability for critical infrastructure.
Transitioning from standard GGG40 to advanced duplex stainless steels and PTFE-lined variants for extreme corrosive environments in chemical engineering.
Development of "Smart Valves" equipped with sensors for real-time flow monitoring, predictive maintenance alerts, and remote actuation via 5G networks.
Low-emission packing and energy-efficient actuators designed to meet the rigorous ESG requirements of the European and North American markets.
The efficiency of the Chinese valve manufacturing ecosystem is unparalleled. At KR, we leverage a vertical integration model that encompasses R&D, casting, precision machining, and rigorous testing within a unified quality management framework (ISO-9001).
R&D department ensures product design and continuous innovation. Our technicians continuously design and develop products that meet customer and market requirements. Our lab provides extensive modern testing capabilities to elevate product performance development. We have 20 series and over 500 varieties.
Production department formulates the production plan to ensure timely delivery. Products are manufactured under strict supervision in accordance with the ISO-9001 quality management system with over 30 production equipment.
Zero leakage is our principle. According to international quality inspection standards, we conduct appearance, size, and pressure inspections, issuing reports in compliance with international standards.
KR VALVE: Over 20 years of expertise in standard and non-standard valve production.
Supplied various water control valves for high-pressure hydraulic management in hydroelectric power projects.
Large-diameter DN2000 valves provided for urban water distribution networks, ensuring minimal pressure loss.
Corrosion-resistant gate valves and butterfly valves optimized for high-viscosity fluid handling.
High-pressure ball valves and gate valves designed to withstand extreme temperature differentials.
Wafer, Lug, and Double Flange types with PTFE or SS304 sealing.
Resilient seat, rising stem, and metal-to-metal seated gate valves.
Dual disc, ball type, and non-return valves for backflow prevention.
Essential for protecting downstream equipment from debris.
Quality is defined by the accuracy of the Cv value, the durability of the seat material (like EPDM or PTFE), and the valve's ability to maintain tight shut-off after thousands of cycles.
Yes, as an OEM/ODM provider, we specialize in non-standard dimensions and material specifications to fit unique industrial requirements from DN50 up to DN3000.
We strictly adhere to DIN, BS, ANSI, and ISO standards. Each batch undergoes pressure testing (PN10/PN16/PN25/PN64) and material certification.
Depending on complexity, standard items are typically delivered within 25-35 days, supported by our monthly inventory updates and efficient production planning.
