API - API REPORT 87-17 - API 14A SUBSURFACE SAFETY VALVE RESEARCH STUDY - YEAR 2 Organization: API
Date: 1988-12-01
Description: The suggested changes to the test procedure included increasing the number of open/close cycles on the test valves, expanding the range of gas and liquid test flow rates to more closely match field conditions, adding hydraulic control line resistance in the gas flow test stand control system to more realistically simulate the long control lines typically seen in field installations, modifying the sand slurry formulation used in Class 2 testing to be more representative of field conditions, adding seal leak testing at elevated temperatures, and adding a drift test to the Class 1 test.
API - API REPORT 88-17 - API 14A SUBSURFACE SAFETY VALVE RESEARCH STUDY - YEAR 3 Organization: API
Date: 1989-12-01
Description: Hydraulic control line resistance variation was added as part of the gas flow test. An elevated temperature test (maximum temperature of 180°F) of the valve seat and control system seals was added to both the Class 1 and Class 2 tests.

Date: 2013-09-01
Description: This standard sets forth the requirements for the following globe valve features: — bolted bonnet, — outside screw and yoke, — rotating rising stems, and nonrotating rising stems, — rising handwheels and nonrising handwheels, — conventional, y-pattern, right-angle, — stop-check (nonreturn type globe valves in which the disc may be positioned against the seat by action of the stem, but is free to rise as a check valve due to flow from under the disc, when the stem is in a full or partially open position), — plug, narrow, conical, ball, or guided disc, — metallic seating surfaces, — flanged or butt-welding ends.
API - API REPORT OSAPR 5 - STUDY OF PRESSURE DROP AND CLOSURE FORCES IN VELOCITY-TYPE SUBSURFACE SAFETY VALVES Organization: API
Date: 1977-07-01
Description: Loss of pressure above a valve increases the flow rate through the valve and also the pressure loss across the valve. For subcritical flow, the pressure loss across a restriction, such as the bean (or choke) used in a safety valve, is proportional to the flow rate of fluids.
API - API REPORT OSAPR 10 - DEVELOPMENT OF METHODS TO PREDICT PRESSURE DROP AND CLOSURE CONDITIONS FOR VELOCITY-TYPE SUBSURFACE SAFETY VALVES Organization: API
Date: 1980-02-01
Description: Loss of pressure above a valve increases the flow rate through the valve, and also the pressure drop across the valve. For subcritical flow, the pressure loss across a restriction, such as the choke or bean used in a safety valve, is proportional to the flow rate of fluids through the restriction.
