Apollo 500 series valves are suitable for a wide range of air‚ gas and liquid applications‚ including hydro-pneumatic storage tanks‚ and as continuous bypass relief valves on service lines. Every valve is configured to your desired set pressure‚ then tested and inspected to ASME standards. If your system changes in the future‚ valves can be reset to a different pressure setting by an authorized ASME valve shop.
Important Ordering Information: When ordering‚ please specify desired pressure setting. A minimum of 5 psi differential or 10% of nameplate set pressure (whichever is greater) is recommended between system pressure and valve setting. For example‚ if you want your set pressure to be 70 psi‚ your system operating pressure should not be more than 63 psi (10% of the set pressure is 7 psi).
Important: Because these valves are custom set to your application‚ they are non-returnable for any reason other than manufacturer defect. If the valve is ordered for the wrong pressure‚ it can be reset by USABlueBook or an ASME valve shop for an additional fee. Contact USABlueBook for more information.
