W1200 DVO Low-Bleed Pneumatic Liquid Level Control

The Model W1200 DVO Pneumatic Level Control is float-activated to operate dump valves and similar devices. It is snap-acting, primarily designed for gas compressor scrubber level applications.

Control may also be used anywhere level switching of a non-pressurized vessel is required. Low level switch design may be used for fuel, lube oil, hydraulic oil and other fluids.

NACE MR0175 is standard for wetted process components. Models are available in all Stainless Steel. These level controls have screw-in connections for direct installation or an optional external float chamber.
