D61 Series

The SERIES D61 contains direct acting (spring loaded) regulators for cost-effective and very low pressure regulation applications. These regulators are best suited for industrial, commercial gas burner applications & combustion systems. The compact construction is ideally suitable for tank blanketing application. These regulators are designed to maintain very low pressure with high inlet pressure upto 11 Barg. (159.4 psig.).

  • 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 improved sensitivity and repeatability of the valve.
  • Special Diaphragm Holding Arrangement:
    Prevents damage of diaphragm and internal parts against passage of full inlet pressure towards downstream.
  • Blanketing Application:
    Suitable for low pressure tank blanketing with inert gas for solvent storage.
  • Tamper Resistant :
    An adjustable set screw with protective cap is a standard arrangement to discourage tampering with pressure setting.
  • Orientation in 360° Direction:
    Regulators can be mounted in any direction and can be easily repositioned while in-line.
  • Exception:
    Regulators with set pressure below 17 mBarg. to be installed such that set screw will remain below diaphragm level.
  • Easy Maintenance:
    Regulator internals can be inspected without removing body from line.
  • Tight Shut-Off Capability:
    Provides excellent tight shut-off capability throughout long working life.

  • Valve Size : 1″ (25 NB) (Other sizes available on request).

    Body Rating : 150# (Higher ratings available on request).

    End Connection : Screwed & Flanged Type (acc. to Std. ASME B16.5).

    Spring Casing & Diaphragm Casing Pressure Maximum : 11 kg/cm2g.

    Temperature Capabilities : -45°C to 200°C with different elastomeric parts.

    Pressure Setting Adjustment : Adjustable throughout the spring range by turning the adjusting set screw.

    Pressure Registration : Internal (Standard); External (Optional).
