TRULY THE ONLY SHIELDED RELIEF VALVE FORESEEN WITH A CAST BRASS CASING PROVIDING TOTAL PROTECTION OF THE PRESSURE GAUGES!

The triple protection of our shielded relief valves renders them totally invulnerable:

  • Independent pressure gauge, mono-block, dustproof
  • Oversized, cast brass body, a true shield
  • Honeycomb rubber envelope for protection against impact damage.
