INSTALLATION, OPERATING, & MAINTENANCE INSTRUCTIONS
Read these entire instructions carefully before installation or servicing.
GENERAL INFORMATION
Safe and efficient operation of industrial installations
requires not only complete knowledge of the
engineering and functioning of all machinery and
equipment but their continuous proper maintenance
as well. Improper operation or maintenance of one
single valve may affect the whole operation. To help
you achieve trouble-free valve performance, general
information is provided here for the optimum operation
and maintenance of your Quadrant steel ball valves
with floating ball design.
DESIGN
All Quadrant F1 series unibody-floating ball valves
are a one-piece body design. The valves are non-
directional and can be installed with either end
upstream.
These
valves
manufactured in accordance with ASME B16.34 and
API 608. Valves have flanges drilled and faced in
accordance with ANSI B16.5.
1. HANDLING VALVES BEFORE
MOUNTING/STORAGE
1.1 Prior to shipment, blind covers are placed on the
inlet and outlet of each Quadrant valve for
protection from mechanical damage as well as
for prevention of intrusion of dust and other
foreign objects into the valve bore during transit.
Do not remove these end protectors before
valves are mounted.
1.2 For valve storage, a dust free place is
recommended. Care should always be taken to
avoid damaging stems. Placing valves directly

on the ground or concrete floor is not
recommended. Under no circumstances should
valves be stored outdoors. Valves are shipped
in the open position to protect the ball surface.
1.3 When moving with a crane, valves should be
positively rigged around valve bodies and end
flanges. In no case should the crane wire be in
direct contact with valve stems or operational
gears.
1.4 The valve must never be stored in the partially
open position. The soft seat can be damaged if
the valve is left partially open for long periods. It
is recommended that the valve be stored in the
full open position to protect the ball and seats.
WARNING
SAFETY FIRST! FOR YOUR SAFETY,
TAKE THE FOLLOWING
PRECAUTIONS BEFORE REMOVING
THE VALVE ASSEMBLY FROM THE
LINE OR BEFORE ANY
DISASSEMBLY.
WHAT'S IN THE LINE?
Be sure you know what fluid is in the line. If there
