Maxitrol 210DZ-1 1/2 Regulator

The Maxitrol 210DZ-1 1/2 Gas Regulator is a specialized zero governor gas regulator designed for high-precision gas flow control in commercial and industrial combustion systems. Featuring a 1 1/2 inch NPT connection and a balanced valve design, this unit maintains a stable outlet pressure between -1.0 to 1.5 inches w.c. even as inlet pressures fluctuate. With a 5 PSI maximum inlet pressure, the 210DZ series is ideal for air-gas premixing applications, atmospheric burners, and low-pressure gas regulation requirements. The rugged aluminum construction ensures long-term reliability in demanding HVACR environments. This Maxitrol 210DZ governor serves as an essential component for technicians requiring exact manifold pressure management for natural gas or propane systems, offering superior lock-up characteristics and sensitive regulation at extremely low flow rates.

Key Benefits for Technicians:

• Zero Governor Precision: Provides exceptional accuracy for air-gas mixing and atmospheric injection systems.
• Balanced Valve Design: Mitigates inlet pressure fluctuations to provide consistent downstream performance.
• Flexible Mounting: Suitable for multi-positional installation in complex mechanical room layouts.
• High Capacity Flow: Engineered for 1 1/2" piping to satisfy high-demand commercial boilers and heaters.
• Durable Construction: Built with high-strength housing to withstand the rigors of industrial mechanical rooms.

Common Questions:

What is the primary function of a zero governor like the 210DZ?
A zero governor, or atmospheric regulator, is designed to reduce gas pressure to zero or slightly negative/positive values, allowing the downstream equipment to "pull" gas based on combustion air flow, ensuring an ideal air-to-fuel ratio.

Can this regulator be used with propane?
Yes, the 210DZ series is compatible with natural, manufactured, mixed gases, liquefied petroleum gases, and LP gas-air mixtures.

Is an external vent limiter required?
The 210DZ should be vented to a safe outdoor location according to local codes, although specific applications may utilize vent limiting devices if indoors and permitted by the authority having jurisdiction.
