に作用する流体圧力を相殺し、主弁を外部より操作して
開閉する比例制御弁に於いて、入口と変圧室の間にパイ
ロット弁口を形成してパイロット弁口を開閉するパイロ
ット弁を配置し、変圧室と出口の間にオリフィスを形成
した比例制御弁。In proportional control valves, which control the pressure in the variable pressure chamber by opening the pilot valve to offset the fluid pressure acting on the main valve, and open and close the main valve by operating the main valve from the outside, there is a pilot valve between the inlet and the variable pressure chamber. A proportional control valve with a pilot valve that opens and closes the pilot valve opening and an orifice formed between the variable pressure chamber and the outlet.
