No delay in valve closure, no water hammer or noise! Operation is quiet and matches a serene surrounding environment!
This product is a high-performance check valve (non-return valve) that safely and economically solves the significant issue of water hammer (water shock) in pumping and water supply systems. Its operation is quiet, matching a serene surrounding environment. Thanks to its patented structure, the valve opens and closes in response to flow without delay, preventing water hammer from occurring. The valve's loss of head is equivalent to that of JIS swing check valves (non-return valves), making it adaptable to a wide range of specifications. Even in large sizes, its simple single-disc structure ensures no failures, significantly reducing maintenance costs. 【Features】 ■ No water hammer ■ Excellent characteristics ■ Easy to handle ■ No water flow detector *For more details, please refer to the PDF document or feel free to contact us.

Company information
Yokota is a water solutions company that creates unique products to solve various problems related to handling water and fluids through new patented theories and know-how. For example, in terms of pumps, they offer a wide range of pumps with features not found in conventional pumps, such as self-priming pumps that can draw in water mixed with air or slurry, and pumps that can de-bubble and degas in one go. Additionally, regarding valves, they have developed various types of valves with simple structures that function cleverly, such as non-slam check valves that do not cause water hammer and automatic control valves that can regulate flow, pressure, and water level using the power of water itself without electrical control. On the other hand, for the metals used in these products, they have independently developed seawater-resistant stainless steel that does not corrode in seawater, as well as other corrosion-resistant and wear-resistant stainless steel alloys, and they carry out consistent production from casting in-house to accommodate challenging liquid qualities. These products are utilized in a wide range of fields, including ultra-pure water production, agricultural irrigation, water treatment, seawater treatment, chemical liquid processing, and pollution prevention treatment.
