and Metering Valves
General
TESCOMMulti-TurnandMeteringValvesarespecicallyengineeredforapplications
requiring dependable controls. These valves are especially appropriate for installations
where high system pressures (up to 10,000 psi) are used.

These are hand knob, manual control. The valve is closed by turning the hand knob
clockwise.

Maintenance
The following procedures are provided to enable the customer to perform all normal
maintenance and repair operations. These operations are more easily performed with
the valve removed from the line. However, in some cases repair may be accomplished
without removal of the valve body as long as the supply has been shut off and the inlet
and outlet pressures have been vented.
An Assembly Drawing and Bill of Material for the valve will be needed to complete
maintenance procedures. The Assembly Drawing and Bill of Material are separate from
this manual and available by contacting TESCOM (see last page for TESCOM contact
information).
