Safety & Shut-off Block Features

N/A

  1. Pressure relief valve (DB12)
  2. Pressure gauge (optional)
  3. Main shut-off valve
  4. Manual bleed valve
  5. 2-way solenoid operated bleed valve (optional)
  6. Accumulator

Construction

N/A The Safety and Shut-off Block consists of a valve block, a built-in pressure relief valve, a main shut-off valve, and a manually operated bleed valve. In addition, an optional solenoid operated bleed valve allows automatic pressure relief of the accumulator or user unit and therefore relief of the hydraulic system in an emergency or during shut-down. The necessary return line connection is provided in addition to the gauge connection.

Standard Models

N/A Model with manually operated bleed valve
The basic model type "M" contains a manually operated bleed valve for manual pressure release of the accumulator.

Model with solenoid operated bleed valve
In addition to the features of the type “M” block, the type "E" model also contains a solenoid operated bleed valve for automatic pressure release of the accumulator.
