W hether you are feeding gas to a portable asphalt plant, drilling rig or hydroponics greenhouse Summit CNG Engineering can design and build a PRS for virtually any flow rate allowing the safe pressure regulating from 4,000 PSI to 45 PSI and control the delivery temperature to 5 Degrees F. Individual customer flow rates may require as few as two control valves or as many as 5 or 6. Summit sizes the control valves to span the customers peak and minimum flow rates over the entire transport delivery pressure range 3,600 PSI to 80 PSI.
