The regulators are made to work with low volume air flow or that is not going anywhere. You can choose from two mounting styles. If you use a panel mounting it has barbed fittings that have connection the size of 1/16″- 1/8″ ID tubing and a panel nut. You also can choose sub base mounting, you can put it right on the valve by hand on the riser block. Pressure rating is 250 psi.
Most all regulators can be made to have 0 psi (which is shut off rating) and go above the range.
If you have questions about these types of regulators, give us a call at 662-871-8403
