| GAS PRESSURE REGULATOR - D61 /- Series |
|
 |
|
The SERIES D61 is 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.
The regulators are designed to maintain very low pressure with high inlet pressure upto 10 Barg (150 Psig). |

| Features |
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 improvement of sensitivity and repeatability of the valve.
Special diaphragm holding arrangement
Prevents diaphragm and internal parts damage against passing of full inlet pressure towards downstream. Relief Valve is not mandatory for regulator protection.
Blanketing application
Suitable for low pressure tank blanketing with inert gas for solvent storage.
Tamper Resistant
An adjusting screw with protective cap is standard 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 7 mbar 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 over long working life. |
