Claims (1)

【実用新案登録請求の範囲】[Scope of utility model registration request] 弁本体■の一部に弁座■を設け、針状弁■との間に形成
される隙間を変化させることにより流量制御する比例制
御弁において、弁全閉時に弁座■と接触する針状弁■の
接触面韻虚２を球面状にしたことを特徴とする比例制御
弁の弁形状。In a proportional control valve that controls the flow rate by changing the gap formed between a valve seat (■) and a needle-shaped valve (■) provided in a part of the valve body (■), the needle-shaped valve that comes into contact with the valve seat (■) when the valve is fully closed is The valve shape of the proportional control valve is characterized in that the contact surface of the valve (2) is spherical.
