一、进口气动单座调节阀概述

进口气动单座调节阀，Pneumatic single seat control valve，美国威盾VTON品牌，由美国威盾VTON气动多弹簧薄膜执行机构和低流阻单座阀组成, 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。进口气动单座调节阀高度低、重量轻、装备简便,新型阀体结构紧凑、流道通畅,具有大的流量系数。适用于对泄露量求严格、阀前后压差低及有一定粘度的场合，广泛应用于电力、冶金、化工、石油、环保、轻工、设备等行业。

Pneumatic single seat control valve, a brand of American VTON, is composed of American VTON pneumatic multi spring diaphragm actuator and low flow resistance single seat valve. It uses compressed air as the power source, pneumatic multi spring diaphragm actuator as the actuator, and uses accessories such as electrical valve locator, converter solenoid valve, and holding valve to drive the valve, achieving switch or proportional adjustment. It receives control signals of 4-20mA or 0-10V from industrial automation control system to adjust various process parameters of pipeline medium, such as flow rate, pressure, temperature, etc. The imported pneumatic single seat regulating valve has low height, light weight, and simple equipment. The new valve body has a compact structure, smooth flow channels, and a large flow coefficient. Suitable for situations with strict leakage requirements, low pressure difference before and after valves, and certain viscosity, widely used in industries such as power, metallurgy, chemical industry, petroleum, environmental protection, light industry, and equipment.

产品有标准型、调节切断型、波纹管密封型、夹套保温型等多种品种。适用液体温度由-200℃至+560℃范围内多种档次。
