ROSS Controls (Troy, MI) introduces its new Hydraulic Block & Bleed valve systems designed for external monitoring, up to Category-4, PL e for safety applications. The ROSS Hydraulic Block & Bleed Series features a manifold base mounted design available in three body sizes (D03, D05, and D07), port sizes SAE-8, SAE-12, and 1-1/4 Code 61 Flange. These valve systems feature a relief valve on inlet, and position sensors for external monitoring. Benefits include:

  • A tamper-resistant design that prevents unauthorized personnel from altering the valve.
  • The safety function of the Hydraulic Block & Bleed Series valve system, to block hydraulic supply pressure and to bleed downstream pressure back to tank. The ROSS HBB Series safety system is a redundant 3/2 normally closed function valve system, spool type design, direct solenoid or solenoid pilot operated.
  • A design for external monitoring for safe redundant operation, and is equipped with position sensors for external monitoring by an electrical safety control system.
