The "LSP flange coupling reinforcement device" is a product that combines a uniquely developed "rubber (SBR) lined packing with a stainless steel core plate" and "lock nuts and bolts (SUS304)." It has high workability and is designed to ensure a consistent compression of the rubber for water-tightness. Improved seismic resistance is expected. 【Features】 ■ Prevents single-side tightening ■ Measures against water leakage ■ Enhanced seismic resistance ■ Approved by the Japan Water Works Association ■ Compatible with both RF and GF flanges *For more details, please refer to the PDF document or feel free to contact us.

"Senobikun" is an underground fire hydrant model Towno LL type that makes it easy to remove hoses and standpipes. The chain ring is also positioned high, allowing for easy lifting of the lid. Additionally, by inserting the standpipe, the L-shaped movable arm stands up, raising the removal operation position by 25 cm. 【Features】 ■ Inserts into Towno type nozzle ■ L-shaped movable arm rises ■ Lift the L-shaped movable arm with both hands ■ The standpipe insertion point detaches from the nozzle *For more details, please refer to the PDF document or feel free to contact us.

The "Air Release Dolphin AHD Type" is an underground fire hydrant that integrates the functions of an underground fire hydrant and an air valve. Since the air valve is located inside the fire hydrant valve shaft, it has the same external dimensions as the JWWA103 underground fire hydrant. Additionally, by replacing the waist section, conventional fire hydrants (JWWA103 standard products) can be used as fire hydrants with air valves. The main body of the fire hydrant complies with the JWWA B 103-2000 standard, and the air valve body meets the JWWA B 137 (formerly JIS B 2063) standard values. The interior coating is an epoxy powder coating that is resistant to red rust. For more details, please contact us or refer to the catalog.

The "Cam Lever Lock Type Rapid Air Valve Kaman Air φ75" is a product that surpasses the functionality of conventional air valves, conforming to the JWWA B137 φ75 standard size. It maintains the ability for operational checks, quick disassembly maintenance, and diverse expandability, while now being compatible with main pipe diameters of approximately 800mm. It is suitable for replacing aging air valves or leaking air valves, as well as for emergency water supply bases during disasters. For more details, please contact us or refer to the catalog.

The "Cam Lever Lock Type Rapid Air Valve Kaman Air F250" has been made compatible with cold regions, such as mountainous areas where freezing is a concern, while maintaining a 30-second operation confirmation and disassembly time, as well as its diverse expandability. It operates normally even when tilted up to 20°. There is high expandability through options such as pipe cleaning functions, internal pipe inspections, and temporary water supply ports for pressure measurement. For more details, please contact us or refer to the catalog.

The "Shinemon C200 Series" is an exhaust valve with operational confirmation that has been developed based on feedback from water supply organizations across the country. In some installation sites, a small amount of exhaust is sufficient, and there was a demand for an air valve that is lower in price than rapid air valves, yet allows for operational confirmation, pipe cleaning, and easy maintenance. This product was developed in response to that request. By turning the butterfly screw or bolt (operational check valve) located on the side of the main body one full turn while the auxiliary valve is open, you can confirm whether the air valve is operating normally. For more details, please contact us or refer to the catalog.

The "Cam Lever Lock Type Rapid Air Valve Kaman Air φ25" is an original product from Kyowa Industry that prioritizes maintenance and operability. The opening and closing with the cam lever allows for quick disassembly and assembly. Additionally, the operation check valve enables the assessment of functionality without disassembly. It is a "new standard" for rapid air valves equipped with maintenance functions and crisis management capabilities for emergencies and disasters.
