EASY MOUNTING PROCEDURE
1.
Disassemble the handle, using an
appropriate hex key. Take off the
panel nut.
SCREWED-BONNET NEEDLE VALVES H-99 SERIES
230
2.
Insert the valve into the panel hole
and reassemble the panel nut.
Firmly tighten the nut.
3.
Reassemble the handle.
Firmly tighten the hex screw.
CLEANING & PACKAGING
Every H-99 series needle valve is cleaned
in accordance with Standard Cleaning and
Packaging (procedure 8184). Oxygen Clean
& Lubricant Free Cleaning and packaging,
in accordance with Special Cleaning and
Packaging (procedure 8185), is available as an
option.
Lubricant free cleaned valves have
signicantly higher actuation torque.

TESTING
The H-99 Series Needle Valve design have
been tested for Proof and Burst.
Every H-99 Needle Valve is factory tested with
Nitrogen at 1000 psi (69 bar).
The maximum allowable leakage across the
seat is 0.1 std cc/min.

PACKING ADJUSTMENT
Due to the varied service applications of the
valve, packing adjustment may be occasionally
necessary.
Valve Packing is factory preadjusted to 1000

Initial packing adjustment is recommended
after installation and prior to start-up.
