XLC 331/431 PN 25
Flow rate and pressure reducing control valve
|
The CSA model XLC 331/431 is a globe pattern hydraulically operated automatic control valve that reduces and stabilizes the downstream pressure to a constant value, regardless of variation in demands, limiting at the same time the flow rate to a maximum value.
