D81 Series

The D81, High performance, High pressure lever type regulator is a direct acting (self actuated spring loaded) regulator, which can be used for all non-aggressive gases. This construction feature i.e. the lever mechanism ensures exact outlet pressure and provides quick response when the flow rate varies .Typical application includes for residential, commercial, industrial applications and also as by-pass regulators for pressure reducing station.

  • Glandless Construction:
    Where positive zero gland leakage is required, the design scores over conventional solutions such as BELLOW seal etc., as the gland itself is eliminated and hence there can’t be gland leakage. Glandless construction eliminates hystersis, resulting in improving the sensitivity and repeatability of the valve.
  • Tamper Resistant:
    An adjusting screw with protective cap is standard to discourage tampering with pressure setting.
  • Orientation in 360° direction:
    Regulator body can be mounted in any direction and can be easily repositioned while in-line.
  • Easy Maintenance:
    Regulator internals can be inspected without removing body from line.
  • Tight Shut-Off Capability:
    Provides excellent tight shut-off capability over long working life.
  • Over / Under Pressure Cut Off:
    Available with integral over / under pressure Cut-off Slam shut valve.
