Claims

[Scope of utility model registration request]

In a pilot-operated automatic on-off valve operated by a solenoid, the discharge side pilot flow path of the cap 17 has an internal circulation hole 21 that opens through the cap 17, and the side wall thereof is located at a position that substantially coincides with the discharge passage hole 14 of the valve box 1. A manual opening/closing device 11 is provided with a communication hole 13 in the internal communication hole 21, and a seat portion 14 that is in close contact with the seat portion 16 of the discharge side pilot flow path of the prefill cap 17 is installed at the opening tip of the internal communication hole 21.
f! - At the same time, by providing a circular groove 20 in the back side of the cap 17 that communicates with the communication holes 13 and 14, a pilot flow path operated by a manual opening/closing device and a pilot flow path operated by a solenoid can be connected. A pilot-operated automatic on-off valve characterized by having both flow paths.
