2 The valves in series 06 are swing wafer check valves, manufactured in accordance with the most severe product norms and in conformity with the quality requirements of EN ISO 900. They are available in the following versions: 06-M6.4 > with carbon steel body suitable for heating and conditioning purposes (HVAC), water treatment and distribution, agricultural applications, compressed air circuits, oils and hydrocarbons. 06-M6.6 > in stainless steel CF8M suitable for chemical plants, food processing and general industrial purposes. (Please ensure the choice of the corresponding item) YES: for installing in horizontal or vertical position.. Compact design.. The special profile with centring lugs (DN 3-0) allows mounting between flanges: PN ANSI The spring allows mounting in all positions. 4. No need for supplementary sealing during installation, thanks to the O-ring seal.. The rounded shape of the shutter reduces head losses and limits the turbulence downstream. 6. The positioning hole simplifies installation In conformity with directive 97/3/CE PED Construction and testing norms (correspondences): Flanges: EN 09, ANSI B6. Design: EN344, EN334 Marking: EN9 Testing: 00% testing in accordance with EN

8 Instruction and Recommendations The information provided here is delivered with each product, and contains Instruction for use and maintenance ; it is also available on our website: (download section) STORING Keep in a closed and dry place. MAINTENANCE The valve does not require maintenance. RECOMMENDATIONS Before carrying out maintenance or dismantling the valve: - be sure that the pipes, valves and fluids have cooled down, - decrease the pressure and drain the lines and pipes in case of toxic, corrosive, inflammable or caustic liquids. Temperatures above 0 C and below 0 C might cause damage to people. INSTALLATION - Handle with care. - Be sure to install in accordance with the flow direction. - Do not weld the flanges to the piping after installing the valve. - Water hammers might cause damage and ruptures. Inclination, twisting and misalignments of the piping may subject the installed valve to excessive stresses. It is recommended that elastic joints be used in order to reduce such effects as much as possible. - When working with high temperature fluids, take care not to burn yourself - Do not dismantle or maintain the valve while the plant is under pressure - Use the O hole for harnessing and lifting. NOTE. This valve is unidirectional: install in accordance with the flow direction arrow indicated on the body. INSTALLATION - Install near the counter flanges, leaving a space in which to place the valve. - Place bolts in the lower holes of the flanges, and position the valve, placing the centring lugs (for DN 3-0) or the body of the valve (DN ) on the bolts. - Insert the remaining bolts. Check that the valve is correctly aligned and tighten the bolts crosswise. DN3-0: suitable for mounting between flanges PN6-0-6-ANSI 0; DN : suitable for mounting between flanges PN0-6-ANSI
