Level 3 reduit Axia Valves

This valve is equipped with a pneumatic or electro-pneumatic actuator, so it can be integrated into simple automated systems.

Technical Characteristics

Component Materials

Advantages • Very compact • Simple 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 double- acting • 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 (suffix 20 FKM) -20°C to +150°C (suffix 30 EPDM) Reliable performance is dependent upon the type of fluid conveyed, component materials and tubing being used. Guaranteed for use with a vacuum of 740 mm Hg (97% vacuum).
