英国斯派莎克BRV2S直接作用式减压阀

英国斯派莎克BRV2S直接作用式减压阀由主阀和导阀两部分组成。 主阀主要由阀座、主阀盘、活塞、缸套、弹簧等零件组成。导阀主要由阀座、阀瓣、膜片、弹簧、调节弹簧等零件组成。通过调节调节弹簧压力设定出口压力，利用膜片传感出口压力变化，通过导阀启闭驱动活塞调节主阀节流部位过流面积的大小，实现减压稳压功能。本产品主要用于蒸汽管路，起减压稳压作用。

Spirax Sarco SpiraxSarco direct acting pressure reducing valve BRV2 from the main valve and pilot valve twoparts. Mainly by the main valve seat, the main valve plate, piston, cylinder liner, springs and other parts.Mainly by the pilot valve seat, valve, diaphragm, spring, adjusting springs and other parts. By adjusting theoutlet pressure adjusting spring pressure setting, the use of outlet pressure sensing diaphragm, the drive piston through the guide opening and closing the valve adjust the main throttle valve flow area size of theparts to achieve the pressure regulator function. This product is mainly used for steam piping, from thevacuum regulator role.

减压阀结构紧凑，重量轻，安装简便，易于调试和设定，维修方便。斯派莎克BRV71和BRV73为球墨铸铁直接作用式减压阀，BRV71为螺纹连接，BRV73为法兰连接，主要用于蒸汽系统。结构紧凑，设计简单，表面高质量的无电极涂镍处理。与BRV2系列减压阀相比，BRV71和BRV73内有压力平衡波纹管，可以平衡主阀头上的压差。主阀为平面密封，具有自清洁功能。斯派莎克SRV2直接作用式减压阀，用于蒸汽，压缩空气或其它气体系统。在负载稳定时，可以准确的控制下游压力。SRV2阀体材质为316L奥氏体不锈钢，因而主要应用于洁净蒸汽系统的压力控制，同时也可用于其它传统工业的蒸汽系统。

Valve compact structure, light weight, easy to install, easy to debug and configure, and easy maintenance.Spirax Sarco BRV71 and BRV73 ductile iron direct-acting valve, BRV71 as threaded connections, BRV73 flange connection, mainly for steam systems. Compact and simple design, the surface quality of the non-coated nickelelectrodes. Compared with BRV2 Series Regulator, BRV71 and BRV73 pressure balanced bellows inside, you canbalance the main valve head pressure. The main valve is flat sealing, with self-cleaning function. SpiraxSarco SRV2 direct acting pressure reducing valve for steam, compressed air or other gas systems. The load is stable, can accurately control the downstream pressure. SRV2 body made of 316L stainless steel, which is mainly used in clean steam pressure control system, but also can be used for other traditional industriessteam system.
