Barksdale’s Heavy Duty Valves provide superior directional control for fluids and gasses up to 6,000 psi in the toughest industrial applications.
Barksdale Heavy Duty Valves use Shear-Seal® technology to provide zero leakage and long life even with contaminated media. They are built with hardened stainless steel seals, bronze bodies, and ductile iron housings for durability in extreme conditions. These valves support high flow and velocity applications with low handle load, even at high pressures, and are suitable for offshore drilling, steel mills, refineries, and power generation.
| Working Pressure (Air) | up to 4,000 psi (276 bar) |
|---|---|
| Working Pressure (Hydraulic) | up to 6,000 psi (413 bar) |
| Back Pressure | Must not exceed 250 psi (17.2 Bar) at return port |
| Media Temperature Range | -40° to +250°F (-40° to +121°C) |
| Rotor Material | 400 Series Stainless Steel |
| Body Material | Bronze |
| Housing Material | Ductile Iron |
Shear-Seal® technology controls media through internal galleries in sealing components rather than across critical sealing faces, allowing it to tolerate contaminants and self-adjust seals.
Typical applications include offshore drilling equipment, steel mills, nitrogen charging panels, refineries, chemical processing plants, and power generation facilities.
