These instructions cover general installation
for Spears ® PVC & CPVC True Union 2000
Full Port 3-Way Ball Valves. All applicable
instructions & procedures should be read
thoroughly before starting. Suitability of
the intended service application should be
determined prior to installation. Plastic piping
systems should be engineered, installed,
operated & maintained in accordance with
accepted standards & procedures.
SPECIAL INSTALLATION INFORMATION
True Union type ball valves use removable end connectors. To avoid problems,
NEVER ASSEMBLE THE JOINT TO THE END CONNECTORS WHILE THEY
ARE ATTACHED TO THE VALVE CARTRIDGE.
Full Port 3-Way Ball Valves: Full Port 3-Way Ball Valve Have Shut off on
Horizontal Branch.
IMPORTANT: Read Precautions & Warnings for all Valve Installations at the
end of these instructions. It is absolutely necessary that all design, installation,
operation & maintenance personnel be trained in proper handling, installation
requirements and precautions for installation and use of plastic piping systems
before starting.
LUBRICATION WARNING: Some Lubricants, including vegetable oils, are
known to cause stress cracking in thermoplastic materials. Formulation
changes by lubricant manufacturers may alter compatibility of previously
acceptable materials and are beyond our control. Lubricants are not required
for installation of Spears Valves.

PRECAUTIONS AND WARNINGS
CAUTION: The system must be designed and installed so as not to pull the
components in any direction. Pipe system must be cut and installed in such a
manner as to avoid all stress loads associated with bending, pulling, or shifting.
All piping systems must be supported.
CAUTION: BEFORE THE VALVE IS CYCLED, all dirt, sand grit or other
material shall be fl ushed from the system. This is to prevent scarring of internal
components; e.g. ball, cup, wedge, seats, etc.
WARNING: System should not be operated or fl ushed out at fl ow velocities
greater than 5 feet per second.
WARNING: All air must be bled from the system during the initial fl uid fi ll.
Pressure testing of the system must not be made until all solvent cement joints
have properly cured. Initial pressure testing must be made at approximately
10% of the system hydrostatic pressure rating to identify potential problems
prior to testing at higher pressures.
NOT FOR DISTRIBUTION OF COMPRESSED AIR OR GAS.
