  • Approvals: EN 88


The FRS 7../6 Line pressure regulators are a balancing type, spring-loaded regulator with an adjustable setpoint. They feature an internal sensor for regulating output pressure.

The FRS series line pressure regulators are recommended for applications when incoming gas pressure from the service regulator needs to be reduced to a suitable pressure for the gas appliance pressure regulator. These are designed for high efficiency appliances, high-turn down appliances, appliances using direct spark ignition or hot surface ignition, and other applications requiring a high performance regulator. The FRS is suitable for dry natural gas, propane, butane, air and inert gases.
