一、进口膜片式蒸汽减压阀概述

进口膜片式蒸汽减压阀（威盾VTON），Diaphragm type steam reducing valve，属于新型先导式超大膜片减压阀, 膜片采用了新型材料,并大大加式了式作面积,因此阀门上游压力或下游负荷细微的变化都能及时准确的反馈到主阀膜片,来调节主阀的开度,确保下游压力的稳定。
进口膜片式蒸汽减压阀特点为：同一个阀体上可安装和互换多个导阀在稳压的同时，实现温度控制、上游压力的控制、远程的开关控制等。

Diaphragm type steam reducing valve (VTON) is a new type of pilot operated ultra large diaphragm pressure reducing valve. The diaphragm uses new materials and greatly increases the working area. Therefore, subtle changes in upstream pressure or downstream load of the valve can be timely and accurately fed back to the main valve diaphragm to adjust the opening of the main valve and ensure the stability of downstream pressure.

The characteristic of diaphragm steam pressure reducing valve is that multiple pilot valves can be installed and exchanged on the same valve body to achieve temperature control, upstream pressure control, remote switch control, etc. while stabilizing the pressure.
