一、进口气动薄膜调节阀概述

进口气动薄膜调节阀，Pneumatic Diaphragm Control Valve，美国威盾VTON品牌，是由美国威盾VTON气动薄膜执行机构和低流阻调节阀组成，以压缩空气为动力源，以气动多弹簧薄膜执行机构为执行器，并借助于电气阀门定位器、转换器电磁阀、保位阀等附件去驱动阀门，实现开关量或比例式调节，接收工业自动化控制系统的4-20ma毫安或者0-10V伏的控制信号来完成调节管道介质的：流量、压力、温度等各种工艺参数。

The Pneumatic Diaphragm Control Valve, also known as the VTON brand, is composed of a VTON pneumatic diaphragm actuator and a low flow resistance control valve. It uses compressed air as the power source and a pneumatic multi spring diaphragm actuator as the actuator. The valve is driven by accessories such as an electrical valve locator, converter solenoid valve, and holding valve to achieve on/off or proportional adjustment. It receives control signals of 4-20mA or 0-10V from industrial automation control systems to regulate various process parameters such as flow, pressure, and temperature of the pipeline medium.

主要产品有单子调节阀，双座调节阀和套筒调节阀

1、单座适用于对泄露量求严格、阀前后压差低及有一定粘度和含纤维介质的场合；

2、双座阀不平衡力小、允许压差大、流通能力大等特点，适用于泄露量要求不严格的场合；

3、套筒阀具有稳定性好，不易产生震动，噪音低，对温度敏感小，适用于压差较大及泄露量要求不严格场合。
