D41 Series — High Flow Pilot Operated Regulators
Rugged high-flow pilot operated downstream pressure regulators for accurate pressure control at widely varying flow rates and supply pressures.
The D41 Series are rugged pilot operated downstream pressure regulators designed for high flow gas distribution and pressure reducing applications. The active-monitoring pilot provides fail-to-open capability on pilot failure. Suitable for gas distribution networks, pressure reducing stations, and industrial process applications. The robust construction makes it ideal for outdoor and demanding environments.
Key Features
- Fail-to-Open Safety — Active monitoring pilot opens main valve on pilot failure preventing dangerous pressure.
- High Flow Capacity — Designed for high flow gas distribution applications.
- Robust Construction — Heavy duty design for outdoor and demanding industrial environments.
- Wide Pressure Range — Covers a wide range of inlet and outlet pressure requirements.
- Easy Maintenance — Modular design allows quick maintenance and part replacement.
Applications
- Gas distribution networks
- Pressure reducing stations
- Industrial process gas
- Pipeline systems
