INSTALLATION – MAINTENANCE MANUAL
Series 19 – Segmented Ball valve
Size 1” (DN25) thru 12” (DN300)
1. DESIGN:
The design features of this valve include a one piece
construction body which results in simplified maintenance
and trouble free operation.
The valve features a characterized ball segment for high
rangeability with Splined stem connection for precise control,
maintenance friendly Segment-Stem assembly, Low friction
Stem and thrust bearing for longer life, Integral actuator
mounting pads, and interchangeable seats.
The valve is either soft or metal seated. Tightness derives
from the spring force pressing the seat against segment. The
structure of the valve supplied may vary, depending on the
customer’s requirements.
2. GENERAL INFORMATION
2.1 - USE
The following instructions are designed to assist in the
unpacking, installation, and maintenance as required for
Flow-Tek products. Product users and maintenance personnel
should thoroughly review this manual prior to installing,
operating, or performing any maintenance.
In most cases, Flow-Tek valves, actuators and accessories
are designed for specific applications (e.g. with regard
to medium, pressure and temperature). For this reason,
they should not be used in other applications without first
contacting the manufacturer.
WARNING:
Before installing the equipment, confirm that
it is suitable for the intended service. The identification
tags describe the maximum allowable service conditions
for this product. Be sure that the installation is protected
by appropriate pressure control and safety devices to
insure that acceptable limits are not excided.
2.2 - OPERATION
Operation of the valve is done by turning the stem a
1/4 turn (90 degrees turn). Clockwise to close, counter
clockwise to open.
2.2A
Valve open position
The double “D” parallel to pipeline (figure 1)
2.2B
Valve closed position
The double “D” perpendicular to pipeline (figure 1)
CAUTION:
Valves with actuators should be checked for
actuator - valve alignment. Misalignment will result in high
operational torque and damage to valve stem and seals.
2.3 - APPLICABILITY
The following instructions are applicable to the maintenance
and installation of Flow-Tek Segmented ball valves. These
instructions cannot claim to cover all details of all possible
product variations, nor can they provide information for every
possible example of installation, operation or maintenance.
This means that the instructions normally include only the
directions to be followed by qualified personal using the
product for its defined purpose. If there are any uncertainties
in this respect, particularly in the event of missing product
related information, clarification must be obtained via the
appropriate Flow-Tek sales office.
