Abstract
An adjustable pressure relief valve has a movable valve closure member with a spring applying a closing force. An adjuster can set the size of this closing force. Pressure responsive means applies an opening force corresponding to a fluid pressure. This pressure responsive means includes a plurality of pressure sensors which can be respectively connected to one or more sources of fluid pressure. Each of these sensors is adapted to apply an opening force to the closure member which has a respective different relationship to the pressure of the source connected thereto. The relief valve opens when the opening force matches the closing force applied by the spring. The different pressure sensors allow the valve to open in response to any one of a range of different pressures.
