PRESSURE RELIEF VALVE

Mod. 9 - 9/A

These valves are designed to protect the reservoirs against the overpressures. As the reservoir pressure exceeds the valve setting, the pallet arises allowing the vapour discharging.

  • Valves Mod. 9/A

    These valves are used when the setting values exceed 800 mbar; the pallet is spring loaded.

  • Rielief Valves with Flame Arrester

    These valves are adopted when a relief valve has to be coupled to a flame arrester. The relief valve body is now machined from the flame arrester upper flange.

  • Valves Mod. 9/TV

    Tightness by elastomeric O-Rings (NBR, FPM/FKM, FFKM) to minimize the leakages.

MAIN FEATURES

  • Replaceable seat

  • Antifreezing pallet

    The drip around the pallet avoids condensate collecting around the seat

  • Pallet guides located above the seat

    This arrangement assures a no-jamming guide of the pallet not affected by contaminant fluids as a close coupling between pallet and guides is not necessary.

  • SETTING

    Any setting available, charging the pallet's dead weight load, between + 20 mbar and + 400 mbar (On request higher sets)

MATERIALS

  • Body

    Carbon Steel
    AISI 304, AISI 316

  • Seat and pallet
