Itron Gas Pressure Regulator Internal Relief Valve

The Itron gas pressure regulator with internal relief valve is a self-operated, spring-loaded regulator. It controls downstream gas pressure in natural gas and LP (propane) systems. Itron's B-Series regulators are also sold under the ROOTS name. The relief versions, often labeled with an "R" in the model name, have a built-in relief valve. If downstream pressure rises above the setpoint, the valve vents the excess gas. This adds overpressure protection without a separate external relief device in many applications.

Key Features:

• Spring-loaded internal relief valve assembly for built-in overpressure protection
• Field-interchangeable adjustment spring, so outlet pressure can be adapted to the application
• Interchangeable orifice for easy maintenance and flexibility
• Controlled breather orifice that reduces pulsation and gives normal action at low flows
• Quick response to changing flow conditions, which helps protect downstream equipment from pressure shock
• Buna-N valve seat and diaphragm components for reliable shutoff
• Durable construction, with cast iron or similar valve bodies in the larger commercial and industrial models
• Available in a range of body styles and connection configurations across the product line

Itron regulators are a long-established choice for residential, commercial, and industrial gas service. Choose the relief version when built-in overpressure protection is needed. Select the specific model, spring range, and orifice for your application's pressure and capacity requirements.
