463 Level 3 reduit Component Materials Technical Characteristics This valve is equipped with a pneumatic actuator. It can be controlled pneumatically or electro-pneumatically (using a NAMUR spool valve or solenoid valve) for integration into automated systems. Available with or without detection. Advantages • Compact solution • Easy to install: ready-to-use • Two seal materials (FKM, EPDM) for a wider chemical and temperature range • Pneumatic or electro-pneumatic • Three versions: normally closed, normally open and doubleacting • Available with or without detection • Compatible Fluids: Compressed air, water, industrial fluids... Other fluids: please consult us • Working Pressure: 10 bar max. • Pilot Pressure: NC and NO: 4.2 to 8 bar Double-acting: 3 to 8 bar • Working Temperature: -20°C to +150°C (EPDM and FKM) With detection: +90°C max Reliable performance is dependent upon the type of fluid conveyed, component materials and tubing being used. Guaranteed for use with a vacuum of 23 mm Hg (97% vacuum).
