一、进口气动罐底调节阀

进口气动罐底调节阀（美国威盾VTON）Pneumatic tank bottom regulating valve，是一种特殊结构型式的单座调节阀，阀体成Y形，阀体流路流畅，流量大，压降损失小，阀座泄漏量符合ANSIBIG.104标准，该气动调节阀配用VPA多弹式薄膜执行机构，基结构紧凑；输出力大，美国威盾VTON气动罐底调节阀最适宜控制容易沉积或含有颗粒的流体。

The Pneumatic Tank Bottom Regulating Valve (VTON) is a special type of single seat regulating valve with a Y-shaped valve body. The valve body has a smooth flow path, high flow rate, low pressure drop loss, and the valve seat leakage meets the ANSIBIG.104 standard. The pneumatic regulating valve is equipped with a VPA multi elastic thin film actuator, with a compact base structure; The output power is high, and the American shield VTON pneumatic tank bottom control valve is most suitable for controlling fluids that are prone to sedimentation or contain particles.
