Description
Bell & Gossett 110199LF Dual Pressure Reducing Valve – 1/2", Lead-Free, #8 Style
Model: 110199LF – Dual Unit, Lead-Free
Connection Size: 1/2" NPT
Pressure Set Points: 12 psig (fill), 30 psig (relief)
Overview:
The Bell & Gossett 110199LF Dual Reducing Valve combines two critical functions in one compact, lead-free brass body—pressure reducing (fill) and pressure relief. Designed for residential and commercial hydronic heating systems, this dual-function valve maintains system pressure while preventing over-pressurization.
Ideal for use in closed-loop boiler systems, the 110199LF features durable brass construction, threaded connections, and integrated components that simplify installation and boost reliability.
Key Features:
-
Dual Function: Integrates a fill valve and a pressure relief valve into a single compact unit.
-
Lead-Free Construction: Compliant with low-lead standards; safe for potable and hydronic use.
-
Reliable Diaphragm Design: EPDM diaphragms in both valves ensure consistent performance and longevity.
-
Built-in Protections: Includes a low inlet pressure check valve and inlet strainer to safeguard the system.
-
Threaded Connections: 1/2" NPT for both boiler and fill lines.
-
Pre-set Pressures: Fill valve set to 12 psig; relief valve set to 30 psig.
