| DB/ - Series - (Downstream Pressure Control Valves ) |
The DB/ Series, Pressure Reducing Regulators are balanced trim regulators. These Pressure regulators are widely used for supplying fuel gas (L.P.G., Natural Gas, etc.) for commercial applications to burners, furnaces and other applications. In general, these valves can be used where required outlet pressure is low with relatively high flow requirement. Different soft seating discs are available for various gases and liquids for wide pressure and temperature range up to 190°C. Because of balanced trim design, these regulators can handle very high variations in inlet pressure without affecting the accuracy of outlet pressure control.
These regulators can be used in active monitor configuration in natural gas regulating and metering station.

| Features |
Easy to Maintain
Compact design with minimum number of moving parts. Actuator Internals, Valve Disc & Trim parts can be replaced, without removing the regulator from the pipe line.
Tight Shut Off Capability
Special trim design eliminates wear & erosion of seating providing excellent tight shut off capability over long working life.
Tamper Resistant
An adjusting screw lock nut and protective cap is standard to discourage tampering with pressure setting.
Balanced Trim
Because of Balanced trim design, these regulators can handle very high variations in inlet pressure without affecting the accuracy of outlet pressure control.
