D81L Series

The D81L, high performance, high pressure lever type regulator is direct acting spring loaded regulator, which is used for reducing pressures for liquid service. this construction feature i.e. the lever mechanism ensures exact outlet pressure and provides quick response when the flow rate varies. Ideally suitable for all liquid applications where constant downstream pressure is required.

  • Can be used as a Active Monitor configuration.
  • Quick & easy replacement of trim parts without removing the regulator body from the pipeline.
  • Ease of maintenance as two bolt connection between the body and diaphragm casing simplifies disassembly.
  • The diaphragm case and /or regulator body can be installed in any position to allow regulator installations in locations where space is a constraint.
  • Available with Internal impulse or External impulse control line.
  • Available in various types of End connections i.e. Flanged & Screwed (NPT & BSPT)
  • Wide range of flow capabilities to meet wide range of process requirements.
  • Tight shut off capability.
