以下是天榆液壓氣動DFY-B32H2/DFYB32H2產品的中英文介紹：

天榆液壓氣動DFY-B32H2/DFYB32H2是一種液控單向閥，它在液壓系統(tǒng)中發(fā)揮著重要作用。該產品可以阻止油流反向流動，起到一般單向閥的作用。同時，它還可以利用控制壓力油，通過控制活塞打開單向閥芯，使油流實現反向流動。這種特性使其在需要嚴格封閉的油路中，能夠進行單向閉鎖，起到保壓作用。此外，DFY-B32H2/DFYB32H2還可作為放油閥或充液閥等使用。

The Tianyu hydraulic and pneumatic DFY-B32H2/DFYB32H2 is a hydraulic controlled check valve that plays a significant role in hydraulic systems. This product can prevent the reverse flow of oil, serving the function of a regular check valve. Meanwhile, it can also utilize control pressure oil to open the check valve core through a control piston, enabling the reverse flow of oil. This feature allows it to perform one-way locking in oil circuits that require strict sealing, serving the purpose of pressure holding. In addition, the DFY-B32H2/DFYB32H2 can also be used as a drain valve or a charging valve.
