115-74 (截止阀) / 1115-74 (角阀)
减压控制阀 / 低流量旁路阀
115-74 (Globe) / 1115-74 (Angle)
PRESSURE REDUCING / LOW FLOW BY-PASS VALVE

　　无论流速和进口压力如何变化，都能够把较高的进口压力减少到恒定较低的出口压力水平上。配置低流量旁路装置分散主阀的压力，以实现低压环境。
　　Automatically reduces a higher inlet pressure to a constant lower outlet pressure regardless of changing flow rate and/or varying inlet pressure. Equipped with a
low flow by-pass feature which bypasses the main valve pressure function for low flow conditions.
