Abstract

A rollover pressure/vacuum relief valve (10) is tested using a kit (150) and an actuation device (100). The valve comprises a valve body (18, 20) and a rollover gravity element (52), which actuates the valve when the orientation of the valve body changes with respect to gravity. The actuation device comprises a valve body engagement member (102) and a rollover gravity element engagement part (104). The device is used when testing the tank by connecting an adaptor (152) to an outlet (16) of the valve. A conduit (156) connects the adaptor to a test unit (160) which alternately pressurises the outlet to test the vacuum relief function (32), and evacuates the outlet to test the pressure relief valve function (22), and, subsequently, the efficacy of the rollover valve member (60, 62). The valve has a circumferential groove (29) to seat a spring clip (202) of a weather cap (200), which clip facilitates connection and removal of the cap from the valve.
