Single and double outlets are lift-type (valve rod rising type) fire hydrants conforming to JWWA B 103 standards. (Models with exhaust valves and air valves are compliant products.)

The single port design protects the threaded parts from sand and other debris by eliminating the nut from the assembly bolt, allowing for disassembly with just one T-shaped wrench. Stainless steel is used for the valve body, valve rod, and flange. By employing a hard lock nut at the valve seat holding section, the workability during valve seat replacement has been improved. 【Features】 75mm - The nutless structure protects the threaded parts from sand and allows for disassembly with just one T-shaped wrench.
