Abstract

Apparatus is provided for testing safety valves without interrupting normal operation of pressure systems or vessels in which they are fitted. A rigid framework (14) is located on the safety valve body (10) with access to the valve spindle (12). There is a coupling (16) between the valve spindle (12) and a connection from a force applying means (ram 22) fixed to the framework for operating the safety valve. That connection includes a stress/strain measuring device (20) from which a readout is recorded at (47) together with valve displacement from a motion transducer (30) and system/vessel pressure (from 40). A hydraulic power unit (26) includes pump, accumulator and flow and return valves, preferably also variable restriction means to control the speed of operation of the ram. Provision is also made for forced re-seating of a safety valve. <IMAGE>
