Page 5: Safety Instructions And Measures
1 Safety instructions and measures Intended use The Type 3353 Angle Seat Valve is designed for on/off service in process engineering and plants with industrial requirements. The valve is suitable for liquids, vapors and gases at tem- peratures from –10 to +180 °C and a pressure rating of PN 40. The angle seat valve is com- bined with a pneumatic piston actuator. - Page 6 Î Check with the plant operator for details on further protective equipment. Revisions and other modifications Revisions, conversions or other modifications to the product are not authorized by SAMSON. They are performed at the user's own risk and may lead to safety hazards, for example. Fur- thermore, the product may no longer meet the requirements for its intended use.
