FBEV-C R744控制阀适采用创新性的内平衡设计，满足R744工作压力高的场景应用；可实现电子膨胀阀和电磁阀的功能。采用大口径结构、轻量化设计, 可直接应用到集成阀岛产品中。阀口采用软密封结构降低内泄漏，使内漏低至≤50ml/min（@1Mpa）。阀体采用金属垫片硬密封，提升外密封性能，以及超临界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.
