Product Description

The Series D53 regulators provide accurate pressure control in a variety of applications: Natural gas system, Fuel gas supply to industrial boilers, Furnances and mixers and commercial or industrial business such as steel mills, asphalt plants and shopping centers.

This regulator is used with double stage pilot pressure loading. The superioir performance of this regulator is due to amplifying effect of the pilot and the two-path control system. Changes in outlet pressure act quickly on the actuator diaphragm to provide fast response to changes. The pilot amplifies system changes, positioning the main valve for precise control.

  • Tight Shut Off Capability Special trim design eliminates wear and erosion of seating, providing excellent tight shut off capability over long working life.

  • Active Monitor Configuration Suitability This model is suitable for use as Active - Monitor Configuration.

  • Double Stage Pilot control Because of double stage pilot design, these regulators can handle high variations in inlet pressure without affecting the accuracy of outlet controlled pressure.

  • Easy to Maintain Sturdy and compact design with minimum number of moving parts. Actuator internals, Valve disc & trim parts can be replaced without removing the regulator from pipeline.

  • Local Position Indicator Position indicator is built in feature for indicating trim movement. Optionally position transmitter can be mounted for position feedback at remote location.

  • Built in Slam Shut Off Option (D53/S) available Built-in Slam Shut Off (with OPSO & UPSO) can be provided as an optional feature. SSV can be provided with local position indicators & Limit switches for remote feedback.
