The arrangement has a flow inlet (4) lockable by a shut-off valve (10) that is controlled by a gas-pressure spring element (16), which is formed by a piston-cylinder-arrangement. A control and regulating device (40) controls a gas pressure of the spring element. A piston (20) of the piston-cylinder-arrangement is movably guided into a cylinder (18) of the piston-cylinder-arrangement, and the gas pressure acts on a surface of the piston. The spring element has a gas inlet (32) attached to a pressurized gas source and a gas outlet (36) flowing into a surrounding area of the valve arrangement.
