When you purchase a high pressure control valve for a pressure regulating
application, you need several other components to make the valve fully
functional. When you order from us we'll help you spec in your package and it'll
be delivered to you fully assembled and ready to install;
however, if you purchase these parts individually, this video will help you
know how to complete the assembly.
I'm Kyle, and today I'll be showing you how
to assemble a high pressure control valve package for pressure regulation.
Before you get started, you'll want to put on your appropriate PPE and be sure
to follow all of your company's safety requirements.
The components of this
package include the valve, a sense line protector to block out the sense pressure
to a device when it exceeds the adjustable limit; a drip pot to knock out
any liquids in your supply gas; a supply gas regulator to provide supply pressure
to the pilot; and the pilot which is responsible for telling the valve what
to do. Depending on how you choose to arrange the components, the number of
elbow and straight connectors will vary but you'll need at least eight (8) quarter
inch by 3/8 inch tubing connectors two quarter inch nipples a high-pressure
quarter-inch t-connector approximately 7 feet of 3/8 inch tubing and Loctite.
Finally, to put the package together you'll need the following tools: a vise,
tubing benders, tubing cutters, a 1/2, 9/16, 5/8, and 11/16" wrench,
channel locks and a crescent wrench.
The way I'll be building this package will have all the components closer together and facing
the front of the valve on the upstream side. We'll be using less tubing this way
and avoid creating areas where someone may try to lift it by the tubing.
The first step is to thread the needle valve into the bottom of the drip pot.
Then connect the supply gas regulator to the drip pot with a quarter-inch nipple
and Loctite. Now mount the valve body in a vise. Pressure reducing valves need to
be fail-closed. Since this is the standard configuration, there's no need
to change the top works of this package. Remove a bolt from the bonnet on the
upstream side of the valve and attach the drip pot and supply gas regulator on
the valve. Then attach tubing connectors to the upstream port of the valve and
the inlet of the drip pot.
Bend, cut, and install the tubing.
Install the pilot near the drip pot.
Remove two bonnet bolts and attach the bracket included on the pilot. Attach the
pressure gauge to the top of the T.
Install the outlet of the sense line protector to the T with a nipple.
Attach a tubing connector to the inlet of the sense line protector and one to the
downstream port of the valve.
Cut, bend and install the tubing to connect these. Next, attach tubing
connectors on the outlet of the supply gas regulator and on the supply gas
filter of the pilot.
Cut and install the tubing to connect these. The supply gas regulator cuts down
the supply gas to the required 30 psi of the pilot. This is preset so you won't
have to adjust it. Attach tubing connectors to both the output of the
pilot and the bottom of the valve bonnet.
Cut, bend and install the tubing to connect these. Finish by installing the
pressure gauge on the supply gas regulator.

We can answer your questions or setup in-person training sessions and demos
for you or your whole team.
You may be using a high-pressure pilot instead of a
30 HPG. For this configuration, the assembly will be the same but the tubing
lengths and angles will look different.
