D61P Series

Series D61P, pilot operated pressure regulators provides accurate downstream pressure control and is best suited for systems involving natural gas, fuel gas, industrial boilers, furnace and mixers & for business such as steel mills, asphalt plants and shopping centers. The superior performance of this regulator is due to amplifying effect of the pilot control system, which changes the outlet pressure and act quickly on the actuator diaphragm to provide fast response to flow changes. The pilot amplifies system changes, positioning the regulators control member to 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.
  • Easy to Maintain :
    Sturdy and compact design with minimum number of moving parts, Actuator internals, disc and trim parts can be replaced without removing main regulator from the pipe line.
  • Built-in Slam Shut-Off Option Available :
    Built-in slam shut-off (with over and under-pressure shut-off) can be provided as an optional feature.
  • Special Diaphragm Holding Arrangement :
    Prevents damage of diaphragm and internal parts against passage of full inlet pressure towards downstream.
  • Tamper Resistant Pilot :
    An adjustable set screw with protective cap is a standard arrangement to discourage tampering with pressure setting.
  • Orientation in 360 Degree :
    Regulators body can be mounted in any direction and can be easily repositioned while in pipeline.
