Safety valve block for the steel industry

SAFETY VALVE

Manual and with Solenoid

The safety valve is a hydraulic isolation and drainage block with safety functions designed for hydraulic accumulators. The block consists of at least three basic components.

  • The main valve is a ball valve (BV), responsible for intercepting and isolating the accumulator from the hydraulic system.
  • The safety component is an automatic safety valve (DBV), preset to the required pressure.
  • The manual drainage system is operated by a needle valve (V), which allows the fluid to drain.
  • An optional component is the solenoid valve (SV), which enables remote fluid drainage.

All models are equipped with a directly actuated safety valve, which drains the fluid in the event of an abnormal pressure increase. As a safety component, it is certified, calibrated and CE marked in accordance with the European Pressure Equipment Directive (PED) 2014/68/EU.

For safety reasons, it is essential to install the safety valve block as close as possible to the accumulators. The safety valve fully complies with all safety requirements set out in Annex I of the PED Directive 2014/68/EU.
