Safety and shut-off blocks


The versions of the HYDAC safety and locking block SAF, its special versions and the DSV10 as a simple variant of the SAF10, are practical hydraulic accessories for blocking and relieving hydraulic accumulators or consumers. They are in compliance with safety regulations in accordance with DGRL97/23/EG, DIN EN 982, EN 14359 and the regulations of the Ordinance on Industrial Safety and Health [Betriebssicherheitsverordung (BetrSichV)].

The optimum combination of the safety and shut-off blocks considerably simplifies the connection between the consumer and the hydraulic system and offer the following exemplary advantages:

  • Minimum of space requirements and maintenance outlays,
  • Minimum of pipework (1 SAF replaces as a rule up to 10 individual pipe connections)
  • considerable reduction of installation time,
  • Transition pieces for various accumulator types and
  • additional valves (controlled check valves, flow valves, etc.)
