进口气动先导式套筒调节阀
产品简介
详细信息
品牌：RETZ/我们一直致力于流体控制领域的持续创新，始于2005……进口先导式套筒调节阀，采用大小阀芯先导式结构。先导式调节阀具有单独的压力平衡先导阀芯以其体积小、结构紧凑、密封效果好、切断能力高、适用范围广和使用寿命长等特点，在自动控制系统中得到越来越广泛的应用。在高温高压差的场合,即使阀座有微小泄漏也可引起汽蚀,长期冲刷阀芯和阀座,会导致阀内件损坏。因此,要求几乎无泄漏,密封,对此场合的阀门是非常重要的。常规做法是加大执行机构输出力提高密封等级retz Pilot operated sleeve regulating valve adopts a pilot operated structure with large and small valve cores. Pilot operated control valves have a separate pressure balanced pilot valve core, which is increasingly widely used in automatic control systems due to its small volume, compact structure, good sealing effect, high cutting capacity, wide application range, and long service life. In situations of high temperature and high pressure difference, even small leakage of the valve seat can cause cavitation, and long-term flushing of the valve core and valve seat can lead to damage to the valve internals. Therefore, it is essential to have almost no leakage and complete sealing for valves in this situation. The conventional approach is to increase the output force of the actuator and improve the sealing level
进口气动先导式套筒调节阀 电动先导式套筒调节阀产品特点：
