进口卫生级减压阀原理特点及品牌（图）

进口卫生级减压阀保证了阀门内腔及表面的卫生要求，同时两端采用卡盘快装连接方式，便于阀门的拆卸和清洗，另外此款减压阀出厂标配隔膜压力表，可对阀门出口端的管道实际压力值的减压要求进行调试和监测。广泛运用于食品，制药，乳品，洁净室，生物工程等高洁净领域

该阀是通过调节，将进口压力减至某一需要的出口压力，并依靠介质本身的能量，使出口压力自动保持稳定的阀门。即通过改变节流面积，使流速及流体的动能改变，造成不同的压力损失，从而达到减压的目的。然后依靠控制与调节系统的调节，使阀后压力的波动与弹簧力相平衡，使阀后压力在一定的误差范围内保持恒定。

Starting with the features and benefitsassociated with the superior design of the Mark 95, Thomas Valve has added aflow-through option that creates more application potential. The MK95FT caneliminate a portion of the by-pass line components by allowing the back pressureregulating valve to be installed in the primary line– not in theseparated by-pass line.

The Mark 95FT is often found in liquidservices such as WFI loops, CIP lines and filling lines. The valve is normallyclosed, allowing flow to pass straight through to downstream users. When demanddownstream is reduced and pressure builds and reaches the setpoint, the Mark95FT will open to relieve and maintain constant pressure. This design allowsfor elimination of pipe"T's" and elbows, reduction of weld joints, simplified by-pass pipingand easier, quicker installation. Due to the unobstructed flowpath through the valve, verylittle to no pressure loss through the valve can be expected. This is a key reason the MK95FT can be installed directly intothe primary process piping.
