1/2" Pressure Reducing Valve, Lead-Free

Bell & Gossett 1/2" Pressure Reducing Valve – Engineered Protection for Hydronic Heating Systems

The Bell & Gossett 1/2" Pressure Reducing Valve is a precision-engineered component designed to regulate and maintain consistent system pressure in closed-loop hydronic heating applications. Manufactured with a rugged brass body and internal components built for performance, this valve ensures safe system fill and pressure stabilization while protecting against the risk of over-pressurization and debris intrusion.

Built for reliability in demanding field conditions, this valve combines pressure regulation, a built-in strainer, and a low inlet pressure check valve into a single, compact unit. It supports fast filling and easy maintenance—ideal for both new installations and system upgrades.

Professional-Grade Features

• Fast Fill Capability: Reduces installation and purging time by allowing a higher flow rate during system startup.
• Low Inlet Pressure Check: Prevents backflow if inlet pressure drops below system pressure, protecting against system depressurization.
• Built-In Cleanable Strainer: Captures sediment and debris before it can enter the heating circuit—removable for periodic maintenance.
• Solid Brass Body and Trim: Corrosion-resistant and built to endure long-term service in closed-loop environments.
• Adjustable Pressure Setting: Factory pre-set to 12 psig; can be field-adjusted to accommodate system requirements.
• Union End Options: Includes 1/2" NPT and sweat tailpiece for flexible connection in various system configurations.
