SERIES D53 REGULATOR WITH BUILT-IN SLAM SHUT DEVICE
SERIES D53 pressure regulator offers the possibility of installing an incorporated slam shut off device whenever it is functioning either as a main or as a monitor regulator.
The incorporated slams shut off device can be retrofitted to SERIES D53 regulator without modifying the pressure reduction assembly. Thus all the specifications are same as that of SERIES D53 regulator.
SLAM SHUT OFF
This device cuts off the gas flow if any failure causes the downstream pressure to rise and reach the set point of the slam shut itself. The slam shut off device can be re-set manually. |

| Features |
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 pipe line.
Built in Slam Shut Off Option 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.
PE D/97/23/EC Compliance
SERIES D53 regulators have PED/97/23/EC compliance certification and also conform to EN 334 requirements. |
