How to Build a Gas Pressure Reducing Regulator Package in 15 Steps

Oil and gas producers use pressure reducing regulators to hold a consistent set point downstream of the valve.

For reducing pressure in high pressure application, you will use a High Pressure Control Valve. 

When you purchase this valve, you need several other components to make that valve fully functional. 

When you order from us, we’ll help you spec in your package and then deliver it fully assembled and ready to install. However, if you purchase these parts individually, this video will help you know how to complete the assembly.   

In this video, Kyle shows you how to assemble a gas pressure reducing regulator with a high pressure control valve package. You can also use this guide to help you build your package.

If you need to configure your valve for back pressure regulation, you can find our video on how to build a back pressure regulator here.

Before you get started, make sure to put on your appropriate PPE and follow all of your company’s safety requirements.  


Parts of a Gas Pressure Reducing Regulator

Parts of a Gas Pressure Reducing Regulator

The components of our High Pressure Valve Package include: 

  • Valve  
  • Sense line protector—blocks out the sensed pressure to a device when it exceeds the adjustable limit
  • Drip pot—knocks out any liquid in your supply gas
  • Supply gas regulator—provides supply pressure to the pilot
  • Pilot—tells the valve what to do

Other Parts Needed

Components Need for a Gas Pressure Reducing Regulator

Along with these parts, you’ll also need the following:  

  • Eight ¼” x 3/8” tubing connectors (approximate)
  • Two ¼” nipples 
  • One high pressure ¼” T-connector (included with 30 HPG pilot) 
  • 7 feet of 3/8” tubing  (approximate)
  • Loctite 

Tools Needed

Tools Need for a Gas Pressure Reducing Regulator

Finally, to put the package together, you’ll need the following tools: 

  • Vise 
  • Tubing benders 
  • Tubing cutters 
  •  ½” wrench 
  • 9/16” wrench 
  • 5/8” wrench 
  • 11/16” wrench 
  • Channel locks 
  • Crescent wrench 

In the video, Kyle builds this package with the components closer together, facing the front of the valve and on the upstream side. This method requires less tubing and avoids creating areas where someone may try to use the tubing to lift the valve. 


How to Build a Gas Pressure Reducing Regulator in 15 Steps

  1. Firstly, thread the needle valve into the bottom of the drip pot.  
  2. Then connect the supply gas regulator to the drip pot with a ¼” nipple and Loctite.  
  3. Now, mount the valve body in a vise. 
  4. Pressure reducing valves need to be fail close. Since this is the standard configuration, there’s no need to change the top works for this package. 
  5. 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.   
  6. Then attach tubing connectors to the upstream port of the valve and the inlet of the drip pot.  
  7. Bend, cut and install the tubing. 
  8. Install the pilot near the drip pot. Remove two bonnet bolts, and attach the bracket included on the pilot. 
  9. Attach the pressure gauge to the top of the T.  
  10. Install the outlet of the sense line protector to the T with a nipple. 
  11. Attach tubing connector to the inlet of the sense line protector and one to the downstream port of the valve.   
  12. Cut, bend and install the tubing to connect these.  
  13. Next, attach tubing connectors on the outlet of the supply gas regulator and on the supply gas filter on the pilot. Cut, bend and install the tubing to connect these.  Note: The supply gas regulator cuts down the supply gas to the required 30PSI of the pilot. This is preset, so you won’t have to adjust it.  
  14. Attach tubing connectors to both the output of the pilot and the bottom of the valve bonnet. Cut, bend and install the tubing.  
  15. Finish by installing a pressure gauge on the supply gas regulator.   

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.
