Chesterton’s  Fluid Regulators provide superior accuracy, reliability and stability to maintain precise flow.

The DualFlow™ Barrier Fluid Regulator monitors both feed and return of fluid from a dual seal for true condition monitoring of both fluid supply and differential in return to indicate potential leakage.

The SingleFlow™ Flush/Quench Fluid Regulator precisely controls supply to single seal flush or quench fluid. Controlled conservation of fluid is assured. These precision instruments share many design and construction features. Laser-cut triangular opening in 316SS controls valves to minimize clogging. Patented Grilamid* bodies are chemically resistant while maintaining permanent transparency and rigidity. Conical flowmeter indicators are self-cleaning through rotation in the fluid flow.

Chesterton’s Fluid Regulators are the perfect companions to high reliability single and dual mechanical seals.

• High accuracy with low maintenance.
• Superior reliability in dual seal barrier fluid service.
• Maintain low, steady flush fluid in single seal service.

Chesterton’s Flowmeters

• High accuracy, low maintenance
  • Chesterton’s DualFlow and SingleFlow Regulators measure fluid volume to within ±10% accuracy throughout their flow range, saving energy and controlling fluid consumption from external source.
  • Eliminates waste from excess flow and prevents damaging fluid deprivation of the seal due to inadequate flow.
  • Fluid regulator bodies are machined from durable nylon to resist chemicals, heat and shock.
  • Front faces are constructed of Grilamid*, an advanced polymer that stays perfectly clear for easy-to-see, reliable readings.
• Superior reliability in dual seal barrier fluid service
• CHESTERTON DualFlow Barrier Fluid Regulator reliably maintains a steady flow of barrier fluid to and from the dual mechanical seal in forced circulation systems.
• Keeps faces uniformly cool, clean and properly pressurized during start-up and operation, resulting in longer seal life.
• DualFlow is the only fluid regulator that detects inboard seal leakage.
• Unique two-way monitoring of barrier fluid supply and return utilizes conical floats within side-by-side flowmeters.
  Any drop in return flow rate indicates inboard seal leakage.
• Maintain low, steady flush in single seal service
  • Chesterton’s SingleFlow Flush/Quench Fluid Regulator maintains low, constant flush to a single mechanical seal, keeping faces cool and clean.
  • Accurate regulation ensures both adequate flow and proper conservation, introducing the minimum required flush into the seal cavity.
  • The SingleFlow can also be used to properly control quench in a process where external quench and drain is used to control face temperature.
