"Senobikun" is an underground fire hydrant model Towno LL type that makes it easy to detach 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 detachment operation position by 25 cm. 【Features】 ■ Inserts into Towno type nozzle ■ L-shaped movable arm rises ■ L-shaped movable arm can be lifted with both hands ■ 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 release valve. Since the air release 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 release valves. The main body of the fire hydrant complies with the JWWA B 103-2000 standard, and the air release 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 "Shinemon C200 Series" is an exhaust valve with operational confirmation that was developed based on feedback from water supply organizations nationwide. 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 rotation while the auxiliary valve is open, you can confirm whether the air valve is functioning properly.
