With over 20 years of specialized experience, KR VALVE has established itself as a premier OEM slow closing manufacturer. Our portfolio exceeds 500 valve types, including high-performance butterfly valves, gate valves, and check valves designed for the most demanding environments.
We don't just manufacture; we engineer solutions. From water treatment plants in Brazil to dam projects in Chile, our products provide the reliability required for large-scale infrastructure. Our commitment to Zero Leakage and international standards (ISO-9001) ensures that every slow closing mechanism we produce meets the pinnacle of global quality.

Slow closing valves are critical in preventing the "Water Hammer" effect—a pressure surge caused when a fluid in motion is forced to stop or change direction suddenly. Our hydraulic cylinder controls allow for a two-stage closing process that dampens surge pressures by up to 90%.
By slowing the final 10% of the valve stroke, our designs protect pumps, pipe joints, and instruments from catastrophic vibration. This extended component lifespan translates to massive ROI for municipal waterworks and chemical plants.
Modern slow closing manufacturers are moving toward IoT. Our latest OEM models support sensor integration for real-time monitoring of closing speed and pressure differentials, enabling predictive maintenance via AI algorithms.
China's valve clusters provide unparalleled access to high-quality ductile iron (GGG40), stainless steel (CF8/CF8M), and specialized coating services. This reduces lead times for complex OEM projects significantly.
As a leading manufacturer, we house modern labs for pressure testing and flow simulation. Our R&D department ensures continuous innovation in hydraulic cylinder control butterfly valves and quick-closing adjusting types.
By controlling every process—from casting to final inspection—we offer competitive pricing without sacrificing the "Zero Leakage" principle essential for global procurement standards.
In mega-cities, sudden pump failure can burst old pipes. Our slow closing check valves and water control valves act as the first line of defense, ensuring city-wide water stability.
Managing the immense pressure of a dam requires valves that close with precision. KR has successfully supplied Chilean and Italian waterworks with large-diameter slow-closing butterfly valves designed for extreme head pressures.
Corrosion resistance is key. Our PTFE lined and SS316 options provide the chemical stability needed for natural gas projects in Russia and chemical plants in Vietnam.
For international enterprises, procurement is about more than just the product. It's about compliance and reliability. KR Valve ensures all OEM products meet:
Technicians develop products tailored to specific market requirements.
Over 30 sets of advanced production equipment ensure high output.
Every single valve undergoes pressure testing before shipment.
The primary advantage is the elimination of hydraulic shock (water hammer). By controlling the closing speed through a hydraulic damper or cylinder, the valve protects the entire piping system from pressure spikes that could cause pipe bursts or pump damage.
We follow a strict ISO-9001 quality management system. This includes 100% pressure testing, material verification (spectroscopy), and dimensional checks against international standards (DIN, ANSI, BS) before any product leaves our factory.
Yes, we specialize in both standard and non-standard valves. We can customize pressure ratings (PN6, PN10, PN16, PN25, 150LB) and materials (Ductile Iron, WCB, CF8, CF8M) to meet your project's specific macro-environment needs.
Lead times vary by complexity, but our production department formulates monthly plans to ensure timely delivery. Most standard orders are fulfilled within 4-6 weeks, with expedited options for critical infrastructure projects.
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 high-precision valve assembly.
We have 20 series and over 500 varieties, supplying international standard and non-standard customized products.
We strictly control the production of each component and assemble it into a perfect finished product with Zero Leakage.
We have competitive price based on we strictly control every process of production by ourselves in our China facility.
We provide professional and complete pre-sales and after-sales service consultation 24/7.
