5/2-Way Double Valves with CROSSMIRROR®-Sensing GENERAL INFORMATION The new ROSS 5/2-way CROSS MIRROR® double valve is designed as a self-monitoring valve. It can be used for controlling pneumatic presses for coldforming of metal (optionally in connection with additional devices such as pilot-operated check valves), if the electric control of the valve is designed in accordance with prEN..."Pneumatic Presses" (June 1998). The mirror-image-type air flow pattern in the CROSS MIRROR® double valve allows an alternating pressure buildup from the de-actuated (pressure port 1 to work port 2) to...

5/2-Way Double Valves with CROSSMIRROR®-Sensing CAUTIONS Installation Double valves should be installed only by persons trained and experienced in the installation of such equipment. Lines Air supply directed through air preparation units and pressure regulator to pressure port 1 requires minimum line capacity of pressure port 1. Lines and line connections must be in accordance with relevant safety regulations, e.g. prEN... Pneumatic Presses“ (June 1998). Cylinder speed regulation When installing components between the double valve and the work element, the relevant safety regulations e.g....

5/2-Way Double Valves with CROSSMIRROR®-Sensing OPERATING INSTRUCTIONS Start-up Prior to start-up, the installation must be checked thoroughly by persons trained and experienced in the operation of pneumatic equipment. Make sure that the maximum operating pressure specified on the valve label will not be exceeded. When operating pressure is applied, the cylinder piston must move into the atrest-position. For further testing, a functional test as well as a pressure failure test must be performed. Functional test Test 1. Actuate solenoid A 2. Actuate solenoid B 3. Actuate solenoid A, then...
