止回阀又称单向阀或逆止阀，是靠管路中介质本身的流动产生的力而自动开启和关闭的，属于一种自动阀门。止回阀用于管路系统，其主要作用是防止介质倒流、防止泵及其驱动电机机反转，以及容器内介质的泄放。止回阀还可用于给其中的压力可能升至超过主系统压力的辅助系统提供补给的管路上。生产的止回阀有旋启式止回阀和升降式止回阀。
浙江欧菲钢制球阀的设计制造保证了最大的使用寿命和可靠性。所有球阀完全满足美国石油协会标准 API 608 & API 6D 和英国标准 BS 5351 的设计要求，并符合美国机械工程师协会标准 ASMEB16.34。
超低温蝶阀采用偏置阀杆和偏心蝶板设计，在开启和处于中间位置时，阀座与蝶板不发生接触，在减小扭矩的同时减少了对阀座的摩擦，提高了阀的耐久性，是一种高性能的调节、切断型阀门。该阀门的设计旨在应对当今工业环境中最难以处理的各种介质，包括液氧、液态天然气和其他低温液体。
