一、进口气动笼式调节阀概述

进口气动笼式调节阀，Pneumatic cage type regulating valve，美国威盾VTON品牌，也叫气动套筒调节阀，是一种压力平衡调节阀,采用笼式套筒导向、单座密封结构，配用多弹簧执行机构或者电动执行机构，流道呈S流线型，选用进口密封环。密封型式采用单座密封，流量特性曲线精度高，符合IEC534-2标准。调节阀动态稳定性好、噪音低、防空化，适宜控制各种温度的高压差流体。对高压差流体介质的温度，压力，流量根据输入模拟信号进行自动化调节。

Pneumatic cage type regulating valve, also known as pneumatic sleeve regulating valve, is a pressure balance regulating valve from the American brand VTON. It adopts a cage sleeve guide, single seat sealing structure, and is equipped with multiple spring actuators or electric actuators. The flow channel is S-shaped, and imported sealing rings are used. The sealing type adopts a single seat seal, with high accuracy of flow characteristic curve and compliance with IEC534-2 standard. The regulating valve has good dynamic stability, low noise, air defense, and is suitable for controlling high-pressure differential fluids at various temperatures. Automatically adjust the temperature, pressure, and flow rate of high-pressure differential fluid media based on input analog signals.

美国威盾VTON气动笼式调节阀有常温型、高温型、低温型、调节切断型、波纹管密封型等多种型式。产品公称压力等级有PN1.6、4.0 6.4、10.0；阀体口径范围DN20-DN300；适用流体温度-150℃ -+560℃范围内多种档次；气动笼式调节阀泄露等级氛分为Ⅳ级、Ⅴ级、Ⅵ级；流量特性有直线、等百分比。多种规格可供选择。
