Norgren Herion Press Safety Valves are now available 24/7 at the Norgren Express webstore. HERION press safety valves conform to DIN-EN-ISO 13849-1 (performance level e, category 4).
Press safety valves are used to control the air actuated systems/machines such as palletizing, wrapping, packaging, processing and power presses, which must always fail in an exhaust mode, therefore leaving the system/machine in a safe pneumatic position.
In these safety critical applications, it is customary to design the valve used in a redundant fashion, therefore having two valves plumbed in series ensuring the system will be in a safe mode even if one of the valves were to fail.
Our innovative design combines this redundancy into one valve body along with an internal pneumatic monitoring system in accordance with OSHA and ANSI. This design uses a unique cross flow pattern along with air logic monitoring which requires no additional costly external proximity sensors and will always fail in an exhaust safe mode.
Herion XSz valves are available at Norgren Express, Norgren’s fast-track, multi-bridge to thousands of quality products and immediate technical engineering advice for pneumatic motion and fluid control. Norgren Express minimizes machine downtime, with most components in stock for rapid dispatch.
