Description

The Universal Shutoff Valves (USOVs) is a normally-closed, three-stage device, designed to terminate fuel flow in less than 100 ms after interruption of the electrical supply current. The 51 mm (2-inch) valve has a maximum operating pressure of 12 411 kPa (1800 psig), and the 76 mm (3-inch) valve has a maximum operating pressure of 6895 kPa (1000 psig). Valve closure is due to the stored energy of a coiled spring in the primary stage.

The liquid-only 51 mm valve is compatible with de-ionized water and most liquid fuels, including diesel fuel, methanol, ethanol, Jet “A”, kerosene, #2 home heating oil, heated light crudes, and residuals.

The gaseous or liquid 76 mm valve is compatible with most gaseous and liquid fuels, including natural gas, propane, ethane, methane, diesel fuel, methanol, ethanol, Jet “A”, kerosene, #2 home heating oil, heated light crudes, and residuals.

All-stainless-steel components with Viton, Vespel, and PTFE seal materials accommodate most fuel contaminates.

An integral 40 µm (nominal) filter screen protects the first and second stage components from damage due to particulate contamination. The fuel isolation valve is constructed of corrosion-resistant materials. Both USOVs will positively seal in a reverse-pressure condition up to 4482 kPa (650 psig).

The valve is designed to be NACE compliant per NACE MR0175-2000 sulfide stress cracking resistant metallic materials for oilfield equipment, NACE International.
