Febco 860 RPZ Backflow Preventer 1-1/2 in. FPT | FE860-150

FEBCO REDUCED PRESSURE ASSEMBLY:

MasterSeries 860 Reduced Pressure Zone Assemblies are used to protect against high hazard (toxic) fluids in water services to industrial plants, hospitals, morgues, mortuaries, and chemical plants. They are also used in irrigation systems, boiler feed, water lines and other installations requiring maximum protection. They feature a bronze body and threaded ball valve shutoffs. Maximum Working Pressure: 175psi.

WARNING!

• All bronze body for durability. One check valve and an air opening port in one assembly.
• Lightweight poppet seals air opening under minimum flow conditions.
• Simple service procedures. All internal parts serviceable in line from the top of the unit.
• Designed for minimum head loss.
• Engineered plastic bonnet protect valve bodies from freeze damage.
• Optional union end ball valves for easy removal and ultimate freeze protection.
• End Connections - NPT ANSI/ASME B1.20.1

• Maximum Working Pressure: 175 PSI (1200 KPa)
• Hydrostatic Test Pressure: 350 PSI (2400 KPa)
• Temperature Range: 32 degrees F to 140 degrees F (0 degrees C to 60 degrees C)
• End Connections: Threaded ANSI B2.

• Valve Body: Bronze
• Elastomers: Silicone
• Springs: Stainless Steel

1. Consult local codes for specific installation requirements and restrictions applicable to your area. It is recommended that system supply pressure be at least 20 psi
2. These instructions apply to models 860; and 860U; sizes 1/2" - 2" only. The valves may be installed only in the orientation/flow direction as shown.
3. The valve assembly must be installed where it is accessible for periodic testing and maintenance. Clearances shown in the installation views apply to exterior; interior and pit/vault installations and are only recommendations. These minimums do not apply to removable protective enclosures. Refer to local codes for actual requirements in your area.
4. PRIOR TO INSTALLING THE VALVE INTO THE LINE; FLUSH THE SUPPLY LINE OF ALL FOREIGN MATERIAL. Failure to flush the supply line may cause the check valves to become fouled and require disassembly and cleaning.
5. After installation SLOWLY fill the assembly with water and bleed air from the body using the # 3 and # 4 test cocks. Test the valve assembly to ensure correct operation. NOTE: All assemblies are tested at the factory for proper operation and leakage. If the valve does not pass the field test; it is most likely due to a fouled check valve. This is not covered by the factory warranty; and the valve cover must be removed and the check seats inspected and cleaned. Any damage or improper operation caused by pipeline debris or improper installation/start-up is not included in the factory warranty. In case of a possible warranty claim; contact your local supplier or FEBCO Representative. DO NOT REMOVE THE VALVE ASSEMBLY FROM THE PIPELINE.
6. The assembly must be protected from freezing and excessive pressure increases. Pressure increases can be caused by thermal expansion or water hammer. These excessive pressure situations must be eliminated to protect the valve and system from possible damage.
7. Plastic testcock plugs and tethers are provided (loose in box) for areas that require them
