Accumulator Safety Block | ASB
The Hyloc Accumulator Safety Block (ASB) is a multifunctional, compact valve assembly that acts as the primary safety interface between a hydraulic accumulator and the operating system. It is designed to meet strict pressure vessel safety regulations, such as DIN 24552 and TRB 403/404, by integrating three essential operations into one block-shaped unit.
- Operating Pressure : High Performance Range
- Application : Industrial & Mobile Systems
About this item
The Hyloc Accumulator Safety Block (ASB) is a critical multi-functional valve assembly designed to protect, isolate, and safely depressurise hydraulic accumulators. It serves as the vital link between an accumulator and the wider hydraulic system, ensuring compliance with pressure vessel safety regulations.
| Feature / Component | Technical Details & Values | Primary Function |
|---|---|---|
| Relief Valve | Poppet type; adjustable ranges: 0–25, 50, 100, 200, 350 Bar | Overpressure Protection: Limits the maximum system pressure to protect the accumulator from failure. |
| Main Shut-off Valve | Ball and synthetic seat type; Manual operation (90-degree handle) | System Isolation: Allows for the isolation of the accumulator from the main circuit for testing or maintenance. |
| Bleed / Manual Valve | Seat type (metal-to-metal sealing); optional solenoid-operated version | Depressurisation: Safely drains stored fluid and pressure from the accumulator to the tank. |
| Operating Pressure | Max Working (Ports P/S): 350 Bar; Port T (Tank): 16 Bar | Safety Rating: Ensures the block can withstand high-pressure hydraulic operations safely. |
