一、进口气动调节型球阀概述

美国威盾进口气动调节型球阀由带定位器的角行程执行器和球阀组成。接受4-20Ma的信号，开度调节，适用于调节流量的场合。球阀与执行机构的连接采用直连方式。具有连线简单，结构紧凑、尺寸小、重量轻、阻力小、动作稳定可靠等优点。

The VTON pneumatic regulating ball valve consists of an angle stroke actuator with a locator and a ball valve. Accepting 4-20Ma signal, adjusting the opening, suitable for adjusting flow rate. The connection between the ball valve and the actuator adopts a direct connection method. It has the advantages of simple connection, compact structure, small size, light weight, low resistance, and stable and reliable operation.
