Abstract
An SPM valve for use in a subsea environment includes a spool selectively movable between first and second positions to thereby arrange the valve in respective armed and disarmed configurations. The particular arrangement of a supply port and discharge port with respect to the spool permits a pressurized working fluid supplied to the supply port to bias the spool to both the first and second positions once an external force is applied to the spool to initially set the spool in either the first or second position.
