Poppet valve ROSS EUROPA

The design of this double valve type is distinguished by two crossflow passages and special valve poppet and spool elements which provide the valve's unique flow characteristics. Two pressure switches are mounted on an adaptor and measure the pressure in the crossflow passages of the main valve. In normal operation the two valve elements move simultaneously and the pressure switches send a matched pair of signals to the control system. If there is a malfunction and the valve elements do not move simultaneously, the pressure switches send an unmatched pair of signals, the control system switches off the valve and prevents any further valve operation. Therefore, the two pressure switches, when correctly connected to the safety circuit, carry out a reliable monitoring function which is in full accordance with the requirements of EN 692.
