進口法蘭Y型止回閥，直流式彈簧逆止閥特征 features

可垂直水平安裝，垂直安裝介質必須有下向上 The valve can be installed vertically and horizontally, and the vertical installation medium must be downward and upward

閥瓣采用彈簧控制，運動更靈活輕便，保證良好的密封 retz品牌 The valve clack is controlled by spring, which makes the movement more flexible and light, ensuring good sealing

全流量、壓損小、防水錘 Full flow, small pressure loss, waterproof hammer

閥瓣有彈性,密封性能好，啟閉迅速，不易堆積雜務 The valve clack is elastic, with good sealing performance, quick opening and closing, and it is not easy to accumulate chores
