HYDAC safety and shut-off blocks are designed to protect, shut-off, and discharge hydraulic accumulators or user units. The compact design simplifies the hydraulic system connection and offers the following advantages:
  • minimum space compared to individual components
  • reduced installation time
  • various system connections
  • system lockout

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.

Repair Kits

Solenoid

N/A 3055295 - New WSM - 2-Way Solenoid Operated Bleed Valve (without coil)
715003 - Old 2SV5 - Coil Kit for 2-Way Solenoid Operated Bleed Valve
2083644 - New WSM - Coil Kit for 2-Way Solenoid Operated Bleed Valve

For complete solenoid replacement, both the 2-way solenoid valve and the coil kit are required 2SV5 coils and WSM coils are not interchangeable.
When replacing a 2SV5 with a WSM you must also replace the coil with the WSM design.

Note

N/A When using hydro-pneumatic accumulators for stored hazardous energy, HYDAC recommends the use of its Safety and Shut-off Block (SAF) with solenoid operated bleed valve.
