Butterfly Valve Type – Compact Design The Robinson Oil Thief is a proven design in oil thieves. The valve closure assembly is on the inside of the barrel, which makes a more compact unit at the bottom, allowing the thief to pass through an opening as small as 5 inches in diameter.
The ZS-1 Zone Sampler allows the product to pass through the sampler as it descends through the liquid. When the device is brought to a stop, the valves close, taking a sample at the desired depth. Stainless steel construction Cylinder height: 12 in. Diameter: 3 in. Capacity: 1.69 pints / 800 ml
