Ball Valve Installation Instructions
Read all applicable instructions and procedures
thoroughly before starting. Suitability of the
intended service application must be determined
prior to installation. Please review "Materials",
in the Spears VALVES PRODUCT GUIDE &
®
ENGINEERING SPECIFICATIONS, SES-1,
for important additional considerations related
to valve installations. Plastic piping systems
must be engineered, installed, operated and
maintained in accordance with accepted
standards and procedures for plastic piping systems. It is absolutely necessary
that all design, installation, operation and maintenance personnel be trained in
proper handling, installation requirements and precautions for installation and
use of plastic piping systems before starting.
Valves are factory sealed with fi xed end connectors and require no adjustments
or maintenance. (See "Precautions & Warnings for All Valve Installations" on
back page).
INSTALLATION INSTRUCTIONS
STEP 1
Prepare connecting pipe as required for solvent cement, thread,
or fl anged connections.
STEP 2
With valve in the open position, support valve body to hold its
weight. Attach one end connector of valve to the pipe, making sure the valve is
aligned with pipe, according to the Solvent Cementing or Threading procedures
on the following pages.
STEP 3
Repeat Step 1 to attach opposite end connector of valve to pipe,
making sure valve is aligned with pipe.
STEP 4
Pressure test system only after all solvent cement joints have
fully cured. Flanged connections may require additional tightening after initial
pressure testing.

SOLVENT CEMENT WELDED JOINTS
For best results, installation must be made at temperatures between 40°F and
110°F. All joint components must be inspected for any breaking, chipping,
gouging or other visible damage before proceeding. All pipe, fi ttings and
BV-3A-0513
valves must be removed from their packaging or containers and exposed to
the installation environment for a minimum of one hour in order to thermally
balance all components. All joining components must be clean and dry.
Be sure the valve is in the open position to aid in evaporation of solvent vapors
which can attack internal components. TAKE EXTRA CARE THAT NO PRIMER
OR SOLVENT CEMENT IS ALLOWED TO COME IN CONTACT WITH THE
BALL OR OTHER INTERNAL VALVE COMPONENTS.

PRECAUTIONS AND WARNINGS
CAUTION: The system must be designed and installed so as not to pull the
valve in any direction. Pipe must be cut and installed in such a manner as to
avoid all stress loads associated with bending, pulling, or shifting. Valve 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.
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.
®
WARNING: Systems must not be operated or fl ushed out at fl ow velocities
greater than 5 feet per second.
All air must be bled from the system during 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.
