Abstract

A control arrangement operates in conjunction with a control scheme to control the maximum pressure level within a conduit network of a fluid system without the need to have high flow pressure relief valves. The control arrangement provides a low flow pressure relief valve connected in parallel with an electrically actuated valve mechanism to trim any over-pressure conditions so that the control scheme has more time to move the electrically actuated valve mechanism to a flow bypassing, pressure relieving position.
