轴流式止回阀采用独特的轴向流动设计，其阀芯与流体流向一致，显著降低流体通过时的阻力损失。阀芯通过弹簧或流体压力驱动，实现快速启闭。当流体正向流动时，阀芯被推开，流体顺畅通过；而当流体反向流动时，阀芯迅速关闭，有效阻止回流，确保系统运行的稳定性和安全性。
缓闭止回阀靠介质本身流动而自动开、闭阀瓣，用来防止介质倒流的阀门。属于一种自动阀门，其主要作用是防止介质倒流、防止泵及驱动电动机反转，以及容器介质的泄放。止回阀还可用于给其中的压力可能升至超过系统压的辅助系统提供补给的管路上。
侧装式超低温球阀专为深冷介质（如LNG、液氮、液氧等）工况设计，采用独特的侧装结构，确保在-196°C~+150°C的极端低温环境中稳定运行。阀体选用优质不锈钢或特殊合金材料，配合精密加工工艺，实现超低温条件下的零泄漏与长寿命，广泛应用于液化天然气、空分设备、化工及能源领域，是严苛工况下流体控制的可靠选择。
