The LS200NDVO is a pneumatic level switch with snap action Dump Valve Operator (DVO) without the pressure regulator for those applications where the system provides a filter regulator for "instrument quality" air or gas as the control medium.

The LS200NDVO is designed for harsh gas compressor scrubber applications. The improved design provides better snap action and dependability with a reduced number of moving parts. A nickel plated body provides enhanced corrosion protection, and the 304 stainless steel float operates in 0.5 specific gravity and heavier fluids.

The LS200NDVO is rated for 2000 psi (13.8 MPa) [138 bar] working pressure and listed for Class I, Division I, Group C & D locations. The DVO valve is 3-way, normally closed with manual operator; all connections 1/8" NPT.
