A-1 Series InjecƟon Safety Valve ApplicaƟons • Sweet to moderately corrosive environments from 40°F to 300° [4°C to 149°C]
Benefits •
Offers a versa le solu on
•
Provides an unobstructed flow path and reliable produc on Design is cost effec ve and easy to run Allows fewer poten al leak paths Reduces problems associated with solids and scale deposi on. Applies to a wide range of subsurface enviroments

The Camco* type A-1 Injec on Safety Valve is designed to prevent wells from flowing back or blowing out in the event of an emergency. The A-1 will open at preset injec on flow rates†, have unlimited se ng depth and, are suitable for severely corrosive environments. These valves are available to 10,000-psi [68,950-kPa] working pressure. The A-1 prolongs the life of the valve by protecting the flapper from erosive injec on flow. The A-1 is available in a variety of materials and features an innova ve and field-proven flapper closure system. This premium flapper mechanism has full, metal-tometal sealing plus a secondary so seat, and it meets a leakage acceptance criterion that is substan ally more stringent than API and ISO specifica ons. The A-1 Injec on Safety Valve is “normally closed”, and open with differen al pressure created by the injec on flow.

OperaƟon The A-1 Series Injec on Valve with the appropriate lock and equalizing sub†† are installed in a landing nipple in the tubing string using conven onal slickline methods. Open The A-1 Series Injec on Valve opens when injec on flow reaches a predetermined rate. The spring-loaded flow tube holds the flapper open and out of the injec on stream flow path, providing an unobstructed flow bore through the inside diameter of the valve. Close The A-1 Series Injec on Valve close when injec on ceases.
