Pressure reducing hydraulic valve with two set points figure XLC 310/410-ND-H PN 16

The CSA model XLC 310/410-ND-H is a globe pattern hydraulically operated automatic control valve that reduces and stabilizes the downstream pressure to two pre-set and adjustable values, regardless of variation in demands and upstream pressure conditions, usually corresponding to night and day regulation. The valve switches from one pressure to the other according to the flow rate, within an adjustable range.

Product features

Applications

• A well-planned pressure management program will extend the life of the system increasing safety and reliability. The automatic control valve CSA XLC Model 310/410-ND-H, thanks to high sensitivity pilots, is designed to automatically per form the downstream pressure regulations in two values, both adjustable, where the lower values usually corresponds to night time low consumption requirements.
