Product Description
The Festo VOFA is a sturdy, purely mechanical control block designed as a press safety valve compliant with ISO 16092-4 and EU Machinery Directive 2006/42/EC. This redundantly designed valve block provides safe reversing of hazardous movements or safe exhausting of pneumatic drives, making it essential for Category 4, PL e safety applications in industrial presses and automated machinery .
Key Features & Advantages:
Redundant Safety Architecture: Redundantly designed valve block with dual valves (2x 5/2 or 2x 3/2 configuration) ensures safe reversing of hazardous movements or safe exhausting of pneumatic drives, achieving Category 4, PL e performance level .
Purely Mechanical Solution: Functions as a press safety valve without integrated diagnostics, providing a reliable, purely mechanical safety solution that meets ISO 16092-4 and EN 692 standards .
Flexible Integration Options: Can be selected as a decentralized individual connection variant with electrical and pneumatic individual connection, or integrated directly into VTSA/VTSA-F valve terminal manifolds .
Integrated Position Sensing: Equipped with switching position sensing via inductive proximity sensors (PNP or NPN, M8x1 connection), enabling diagnostic evaluation of actuation and feedback signals .
Robust Metal Construction: Sturdy and durable metal components with IP65/NEMA 4 protection, operating pressure range of 3 to 10 bar, and flow rates up to 1,050 L/min .
Equipped with VSVA Valves: Built with proven Festo VSVA pneumatic valves for reliable and consistent safety performance .
