Xylem-Bell & Gossett 110197LF F-3 Dual Unit Combination Valve 1/2" NPT 12 PSI/30 PSI Lead Free

The Xylem-Bell & Gossett 110197LF F-3 Dual Unit Valve combines a pressure reducing valve with a noncode relief valve, providing fill and overpressure protection for hydronic heating systems. The reducing valve is factory set at 12 PSI (adjustable from 10 to 25 PSI), while the relief valve is set at 30 PSI non-adjustable.

Key Features:

• Fast fill feature reduces start-up time and labor
• Lead free brass body with corrosion resistant wetted parts
• Low inlet pressure check valve helps prevent loss of system pressure if supply water drops below system pressure
• Convenient cleanable strainer designed to prevent dirt and sediment from entering the system
• Large diaphragm for positive relief valve action
• CSA certified to NSF/ANSI 372 for less than 0.25% lead content

Specifications:

• Connection Size: 1/2" NPT (boiler and fill)
• Maximum Operating Temperature: 225°F (107°C)
• Maximum Operating Pressure: 125 PSIG (862 kPa)
• Material: Lead Free Brass
• Dimensions: 6-7/16" inlet to outlet length, 6" height

Note: This noncode relief valve is not to be used alone to protect the system. An ASME type safety relief valve must also be installed for output overpressure protection.
