Reinstalling wire mesh inlet filter - Insert filter into primary inlet port. It must then be
expanded to fit correctly. This can be accomplished by inserting a metal tool the same
size as the port and then lightly tapping it with a hammer

media compatible with the use of the regulator and pressurized to check for internal and
external leakage and operating characteristics.
Valves - TESCOM Multi-Turn
and Metering Valves
General
TESCOM Multi-Turn and Metering Valves are specifically engineered for applications
requiring dependable controls. These valves are especially appropriate for installations
where high system pressures (up to 10,000 psi) are used.
Actuation Types
These are hand knob, manual control. The valve is closed by turning the hand knob
clockwise.
Operation (Control Knob Adjustment)
The valve is closed by turning the hand knob clockwise and opened by turning the hand
knob counterclockwise. The hand knob rotation changes the position of the valve stem in
relation to the seat.
TESCOM valves will operate with any liquid or gaseous media compatible with the wetted
materials. A filter is recommended for use in all but the cleanest media. Gaseous media
should be free of excessive moisture to prevent icing of the valve at high flow rates.
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).
