Barksdale Heavy Duty Valves
Shear-Seal® directional control valves for demanding high-pressure fluid and gas systems
Able Instruments offer the Barksdale Heavy Duty Valve range for reliable directional control in demanding high-pressure fluid and gas systems. This valve family includes Series 140, 200, 920, 5620 and 3760, each designed to deliver robust, repeatable performance in harsh industrial environments.
Barksdale Heavy Duty Valves are based on the proven Shear-Seal® operating principle, using a rotating rotor and stationary seal to achieve positive shut-off and consistent switching under high pressure. Unlike conventional spool or poppet valves, this design minimises internal leakage, reduces wear, and maintains reliable operation even with contaminated media or high flow velocities.
Key Features:
- Shear-Seal® directional control technology: Rotating rotor and stationary seal provide positive shut-off and reliable switching under high pressure.
- Designed for demanding service: Engineered for use in harsh industrial environments where durability and reliability are critical.
- High-pressure capability: Suitable for high-pressure hydraulic, pneumatic and gas systems depending on series and configuration.
- Contamination tolerance: Proven operating principle maintains performance even with contaminated media.
- Wide series coverage: Series 140, 200, 920, 5620 and 3760 provide flexibility across port sizes and system requirements.
- Low operating effort: Shear-Seal® design reduces actuation forces compared to conventional valve technologies.
- Configurable actuation options: Manual and spring-return versions available to suit different operating requirements.
- Broad industrial applicability: Used in drilling equipment, steel production, chemical processing and power generation systems.

The Heavy Duty range supports a wide variety of configurations, including multiple port sizes, flow paths and manual or spring-return actuation options. This flexibility allows engineers to select a valve solution matched precisely to system pressure, media type and operational requirements.
Commonly used in drilling equipment, steel mills, nitrogen charging systems, refineries and power generation plant, Barksdale Heavy Duty Valves provide a dependable solution where durability, contamination tolerance and long service life are critical to system uptime.
