FAQs
SCVA321FH0C02400 uses a G1 port size, a standard in many industrial pneumatic systems. This enables straightforward integration with existing piping, manifolds, and DIN-form fittings, reducing the need for adapters and minimizing installation time in new builds or retrofits.
The self-monitoring design eliminates the need for external cyclical monitoring or evaluation equipment. This reduces potential fault pathways, shortens maintenance windows, and enhances fault detection responsiveness, contributing to higher overall safety integrity in DIN EN ISO 13849-1 PL e applications.
Yes. The valve is designed to support safety functions evaluated up to ISO 13849-1 PL e, meeting stringent performance levels for pressure build-up and venting sequences. This makes it well-suited for safety-critical lines in industrial automation where DGUV approval is also advantageous.
A 3/2 NC (normally closed) configuration provides predictable fail-safe behavior, ensuring venting or isolation until actuated. In safety-critical lines, this reduces risk during power loss or control faults and simplifies integration with safety PLCs and interlock schemes.
The self-monitoring design minimizes ongoing evaluation needs, lowering routine maintenance. The aluminium body and polyurethane seals offer durability in harsh environments, reducing expected service intervals. Regular inspection of ports, seals, and electrical connections is still recommended to sustain maximum performance.
