Barksdale Series 8020 Pressure Relief Valve
High-flow hydraulic pressure relief valve for reliable system over-pressure protection
Able Instruments offer the Barksdale Series 8020 Pressure Relief Valve for reliable over-pressure protection in hydraulic systems. Designed to protect pumps, pipework and system components, the Series 8020 provides controlled pressure relief in demanding industrial and mobile hydraulic applications.
The Series 8020 pressure relief valve is engineered for high-flow hydraulic service and offers stable, repeatable relief performance across a wide range of pressure settings. When system pressure exceeds the configured set point, the valve opens to divert excess flow, helping to prevent damage caused by pressure spikes and abnormal operating conditions.
Key Features:
- Hydraulic over-pressure protection: Designed to safeguard hydraulic systems from pressure spikes and abnormal operating conditions.
- High-flow relief capability: Suitable for applications requiring rapid pressure relief at higher flow rates.
- Multiple pressure ranges available: Configurable pressure settings allow accurate matching to system requirements.
- Stable and repeatable performance: Provides consistent relief behaviour to support reliable system operation.
- Factory set or field adjustable options: Available to suit different installation, commissioning and maintenance needs.
- Robust construction: Engineered for long service life in demanding industrial and mobile hydraulic environments.
- System safety focused design: Helps reduce the risk of component damage, unplanned downtime and safety incidents.

Multiple pressure ranges are available, allowing the valve to be matched accurately to specific system requirements. Valves can be supplied factory set or configured for field adjustment, depending on the application and maintenance strategy. Robust internal construction and corrosion-resistant materials support reliable long-term operation in demanding hydraulic environments.
Typical applications include hydraulic power units, pump protection circuits, accumulator systems and industrial hydraulic machinery, where dependable pressure relief is critical to system safety, performance and uptime.
