FBEV-C R744控制閥適采用創(chuàng)新性的內(nèi)平衡設(shè)計(jì)，滿足R744工作壓力高的場景應(yīng)用；可實(shí)現(xiàn)電子膨脹閥和電磁閥的功能。采用大口徑結(jié)構(gòu)、輕量化設(shè)計(jì), 可直接應(yīng)用到集成閥島產(chǎn)品中。閥口采用軟密封結(jié)構(gòu)降低內(nèi)泄漏，使內(nèi)漏低至≤50ml/min（@1Mpa）。閥體采用金屬墊片硬密封，提升外密封性能，以及超臨界R744的耐久性。

FBEV-C R744control valve adopts innovative internal balance design to meet the application of R744 with high working pressure; It can also have the functions of expansion valve and solenoid valve. With large diameter and lightweight design, it can be directly applied to integrated valve island products. The soft sealing structure is adopted to further reduce the internal leakage to ≤ 50ml / min (@1MPa). The metal hard sealing improve the external leakage sealing performance, as well as the durability of the supercritical R744 conditions.
