Old-type fist stage valve housings
with (G 1/8”) threads are equipped
with nylon gaskets seats.
It is not normally necessary to
change these seats during service.
However, if the seats are subjected
to a great deal of over-tightening,
the interior orfices can be reduced
in diameter, significantly reducing
flow and performance. Compare
installed gasket orifices with a new
gasket, and replace as necessary.
Gaskets must also be replaced
after a long time acid-bath.
Sealing surfaces
a. G1/8’’-port with gasket.
b. UNF 3/8’’-port with o-ring

When servicing the regulator following
parts should be replaced:
See chapter Servicekit.
1. All o-rings
2. Diaphragm
3. Cup filter
4. Valve seat
Cleaning:
If corrosion or salt deposits are in
evidence, place all metal parts in 15
percent hydro-chloric acid.They should be
left in the acid for about 10-15 minutes.
Then, rinse the parts thoroughly and blow
dry with air.
SERVICE INSTRUCTIONS
Checking:
Check the following parts very carefully.
Replace even if only slightly damaged.
Valve needle (8). Check to make sure that
the needle is straight.
The blind screws (9) and (13), check to
make sure the sealing surfaces are
undamaged. Also check that the threads
are not damaged.
The valve housing (11), check to make
sure the threads and also the sealing
surfaces for the o-rings are undamaged.
The connections (17) or (20), check to
make sure the sealing surfaces for the
o-rings are undamaged.

Assembly
Lubricant:
Grease:
1. Install the o-ring (10) on the blind
screws (9), low pressure supply and the
o-ring (12) on the blind screw (13), high
pressure supply. Lubricate the blind
screws and the o-rings.
2. Screw in the blind screws in the
LP-HP outlets. Use a 5 mm Allen
wrench an tighten hard.
3. Install the o-ring (14) on the valve
seat (15) and then install the valve
seat with a seat drift.
4. Lubricate the point of the valve needle
(8) and install it in the lower diaphragm
center (7). (The grease will help retain
the needle on the lower diaphragm
center during the assembly process).
5. Install needle (8) and center (7) in
the valve housing.
6. Press the diaphragm (6) into the
groove of the valve housing. Use a
blunt-pointed instrument to set it
firmly in place.
NOTE:
The diaphragm (6) must be replaced on
every removal.
7. Reverse the valve housing.
8. Install the valve piston (16) on the
valve needle.
9. Install the spring (17) on the valve
piston.
