GR400 Gas Regulator

• Dual‑stage pressure reduction 

• High stability and reduced venting

• Landis+Gyr’s patented active‑monitor system delivers robust over‑pressure protection through redundant regulation, fail‑safe design, and partial‑relief capability.

• Environmental design that minimises venting to atmosphere, supporting sustainability goals

Reliable, Consistent Performance

• The GR400’s dual‑stage pressure reduction ensures consistently stable outlet control—even under wide fluctuations in inlet pressure. With one configuration that works across all networks, operators can reduce complexity, cut inventory costs, and simplify upgrades.

Engineered for Accuracy and Efficiency .

• By providing high stability and reduced venting, the GR400 enhances metering accuracy, improves peak‑load management, and supports better overall system performance. Fewer variants mean easier planning, smoother deployment, and lower lifecycle costs.

Built-in Safety

• A patented active‑monitor system provides robust over‑pressure protection through redundant regulation, fail‑safe design, and partial‑relief capability—without the maintenance downsides of traditional OPSO (Over-Pressure-Shut-Off) regulators.

Environmental Design

• Engineered to minimise venting to atmosphere, the GR400 reduces environmental impact and helps avoid unnecessary callouts, lowering operational costs.
