FW Murphy DVU175 Pneumatic Dump Valve

The FW Murphy DVU175 is a high-pressure pneumatic dump valve designed for reliable fluid control in oil and gas production environments, such as separators, treaters, and free water knockouts. This valve operates by using pneumatic pressure to control the dumping of liquids, ensuring efficient level management and preventing overfill or equipment damage. Key features include a robust diaphragm-actuated design, corrosion-resistant materials, and a high maximum working pressure of up to 1750-1800 PSI, making it suitable for demanding applications. Advantages over similar products include its compact size, ease of maintenance with field-replaceable parts, and proven reliability in harsh conditions, reducing downtime compared to less durable alternatives. Benefits include precise control, low leakage, and compatibility with various pilot systems. Drawbacks may include the need for periodic diaphragm replacement in abrasive fluids and higher initial cost versus basic manual valves. This unit is ideal for upstream oilfield operations, compressor stations, and industrial pneumatic systems where safety and efficiency are critical. Based on image analysis, this asset appears unused (new/open box condition), with no visible wear, scratches, or corrosion. The label confirms part number 55700301, model DU175 (likely a variant of DVU175), and barcode 60000659725. No serial number is visible on the faceplate. There are no apparent parent/child assets like attached sensors or controllers; it is a standalone valve with brass fittings for inlet/outlet. Estimated market price range is $400-$600 USD for new/unused units, based on comparable listings on industrial surplus sites (e.g., eBay, GlobalSpec); this is an estimate as exact sales data varies.
