"Y" Pattern Design Reduced Pressure Zone AssembliesAvailable Sizes: 3/4 to 2 in. (20 to 50mm)
Series 825Y "Y" Pattern Design 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 (12.1 bar).
Installation Instructions
1. Consult local codes for specific installation requirements and restrictions
applicable to your area. It is recommended that system supply pressure
be at least 20psi (138 kPa).
2. These instructions apply to the FEBCO Series 825Y, sizes
3⁄4"- 2"
(20 – 50mm) only. The assembly should be installed in the horizontal
position with the relief valve on the side.
3.
THE VALVE ASSEMBLY MUST BE INSTALLED WHERE RELIEF
VALVE DISCHARGE WILL BE ACCEPTABLE, OR WHERE RELIEF
VALVE DISCHARGE CAN BE COMPLETELY DRAINED.
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. The
valve cover(s) 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.
