Safety Blocks

Our accumulator safety block is a multi-functional valve placed between the hydraulic accumulator and the operating system.

The safety block allows for isolation of the accumulator for maintenance or system testing, and will function as an emergency shut-off device or pressure relief valve to protect the hydraulic system from over-pressurization or system failure.

Our accumulator safety blocks incorporate the following components:

  • 90-degree full-orifice ball valve to isolate the accumulator from the system
  • Manual adjustable safety relief valve
  • Manually-operated bleed valve; bleeds down accumulator safely
  • Optional female port for pressure gauge options
  • Manual release handle standard
