Flanged End Ball Valves

Installation, Operation and Maintenance Manual

Note: Before using a valve, read the entire IOM carefully and make sure you have a clear understanding of all

information included.

This manual describes the procedures for the safe and efficient installation, operation and maintenance of

Flo-Tite Flanged Series Ball Valves. Failure to follow the procedures in this manual may result in Flo-Tite

warranties being voided. Problems with the operation and maintenance of these valves should be directed

to the nearest Flo-Tite Representative.

The Flo-Tite Flanged Series are designed as one piece body. This line of valves utilizes the "free floating" ball

principle. The ball is not fixed, but is free to move with the line pressure. As a result, these valves are capable

of tight shut-off with the flow in either direction or dead-ended, regardless of the position of the valve in the

line. The downstream seat, which is opposite the pressurized side, of a closed valve must carry the load

exerted by the line pressure on the ball, while the upstream seat is subject to little load or wear. For this

reason, it is sometimes possible to increase useful seat life by turning the valve end-for-end in the pipeline.

INSTALLATION:

A. Receiving and Preparation Procedure

A1. Remove shipping protection

A2. Inspect the valve(s) for transportation damage*

A3. Inspect the valve bore and remove any debris

A4. Cycle the valve and inspect the valve for smooth operation, size permitting

A5. As shipped from the factory, valves may contain a silicone based lubricant. This is for break-in and may

be removed if it is objectionable for a particular application by disassembling and solvent washing.

*If transportation damage is found, immediately take pictures for record purposes and contact the inbound

carrier to submit a claim.

B. Installation Procedure

B1. General – The valve may be fitted in any position in the pipeline. Prior to installing the valve, the pipe on

either side of the intended installation should be checked to be free of dirt, debris, weld slag, etc. to prevent

damage to the seats, seals and surface of the ball. The piping must also be free of tension or compression.

WARNING

– Never use the valve as a pipe support or structural member.
