6. After installation, cycle valve several times to assure smooth operation.

OPERATION

1. A quarter turn of the handle clockwise closes the valve and a quarter turn counterclockwise

opens the valve. Visual indication of the ball position is determined by the handle or stem

position: when the handle, or the stem flats, inline with the piping the valve is open; across the

line, the valve is closed.

2. Cryogenic ball valves perform best with the ball either fully open or fully closed. Consult the

factory regarding characteristics of the media or pressure drop for applications other than fully

open or closed.

3. Any media that might solidify, crystallize or polymerize should not be allowed to stand in the

ball valve cavities. In the event that this should happen, DO NOT force the valve in either

direction; disassemble and clean before resuming service.

4. Break-away torque (i.e., force which must be exerted to start moving the valve ball) will vary

depending on the media, pressure and length of time between cycles, as well as valve seat and

packing materials. Consult the factory for specific values.

MAINTENANCE

A repair kit containing the appropriate number of components is available for rebuilding each size

and configuration of valve. Be sure to specify the complete valve model number, and the TBV Inc.

sales order number that is stamped on the valve body, when ordering. Additional components, such

as balls, stems, etc. are also available for repair purposes. Refer to illustration for part

identification.

AT ALL STAGES OF THE FOLLOWING DIS-ASSEMBLY AND RE-ASSEMBLY

PROCEDURES, CARE MUST BE TAKEN TO AVOID DAMAGE TO ALL SEALING

SURFACES.

1. Before removing valve from line, make absolutely certain that line pressure is shut down, and

that the line is vented, to remove all pressure from the valve. Operate the valve to assure that

there is no pressure or media trapped within the valve body cavity. Flush the line as

appropriate to remove harmful chemicals that may be present.

2. Remove the valve from the line. Be certain to fully decontaminate the valve, if it has been used

in services that have any degree of toxicity. Wear protective gloves and clothing as appropriate

to avoid contact with potentially harmful chemicals.

3. Before removing valve from line rotate ball into the open position.

4. Remove four body bolts and disassemble from line making sure to allow sufficient pipe end

clearance for center section removal.

5. Remove body seals from end plates.
