德國LOCKE洛克進口電子式電動雙座調節(jié)閥，由LOCKE系列(或PSL系列)直行程電子式電動執(zhí)行器和直通雙座調節(jié)閥體組成。電子式電動雙座調節(jié)閥內含飼服功能，接受統(tǒng)一的4-20mA或1-5V·DC的標準信號，將電流信號轉變成相對應的直線位移，自動地控制調節(jié)閥開度，達到對管道內流體的壓力、流量、溫度、液位等工藝參數的連續(xù)調節(jié)。

電子式電動雙座調節(jié)閥采用雙導向結構，具有結構緊湊、重量輕、動作靈敏、閥容量大、流量特性精確、拆裝方便等特點。廣泛應用于精確控制氣體、液體、蒸汽等介質，特別使用于壓差較大且對泄露量要求不嚴格干凈介質場合。

German locke electronic double seat control valve is composed of lock series (or PSL Series) straight stroke electronic electric actuator and straight through double seat regulating valve body. The electronic electric double seat control valve contains feeding and service function. It receives the unified standard signal of 4-20mA or 1-5V · DC, converts the current signal into the corresponding linear displacement, and automatically controls the opening of the regulating valve, so as to continuously adjust the process parameters such as pressure, flow, temperature and liquid level of the fluid in the pipeline.

The electronic electric double seat regulating valve adopts double guiding structure, which has the characteristics of compact structure, light weight, sensitive action, large valve capacity, accurate flow characteristics and convenient disassembly and assembly. It is widely used in the precise control of gas, liquid, steam and other media, especially in the case of large pressure difference and not strict requirements on the leakage of clean media.
