Claims

[Scope of utility model registration request]

a vertical through hole, a first horizontal communication hole that communicates with the vertical through hole, and a second horizontal communication hole that is arranged in parallel with the second communication hole and communicates with the vertical through hole. A first rotating body having a first communication hole opposite to the first communication hole is provided in the vertical through hole of the valve casing, and the second communication hole is provided in the valve casing. A third rotary piston is fitted in which a second rotary body having a second communication hole facing the hole is closely connected so as to be integrally rotatable, and the first communication hole and the second communication hole communicate with each other. A valve made of FRP, characterized in that a communicating hole is provided, and a needle valve capable of opening and closing the third communicating hole is provided with the rotary piston.
