LS200NDVOR is a float-activated, pneumatic-vent level device used to operate dump valves or similar devices.

The Murphy Gas Compressor Scrubber Level System (SLS)

The LS200NDVOR provides a 2” NPT mounting with a pneumatic snap action output for interfacing with pneumatic devices such as our DVU scrubber dump valve or with other pneumatic instrumentation. This unit is supplied with a pressure filter regulator and Murphy pressure gage which are recommended for improved system life and trouble-free operation.

LS200NDVO

Pneumatic level switch with snap action Dump Valve Operator (DVO) without the Pressure Regulator for those applications

The system provides for liquid control in gas scrubber applications, by dumping liquids to drain and protecting compressors with a high liquid level switch. Wetted metal parts are made to survive constant use in corrosive environments. See Bulletin: SLS-04005B for more details.
