PRODUCT INFORMATIONS
Product parameters
Precision‑calibrated plastic exhaust valve with cracking pressure of 5–8 mbar, enabling automatic overpressure degassing. The unidirectional sealing mechanism completely blocks reverse oxygen ingress, while the multi‑layer sealing gasket maintains airtight integrity across extreme temperatures (–40°C to +83°C). Engineered for demanding industrial, automotive, and packaging applications where reliable pressure management and contamination prevention are critical.
Accurate 5–8 mbar cracking – triggers degassing precisely at overpressure, eliminates manual monitoring.
Zero backflow – uni‑directional valve design ensures absolute oxygen penetration resistance.
Thermal stability – multi‑layer gasket delivers consistent seal performance under high/low temperature cycling.
Automatic resealing – closing pressure ≤2 mbar minimises gas loss and restores closure rapidly.
Durable & lightweight – engineered plastic resists corrosion, chemicals, and mechanical stress, offering cost‑effective replacement for metal alternatives.
Industrial containers – degassing volatile chemicals, solvents, and sealed drums.
EV battery packs & energy storage – pressure equalisation and emergency venting.
Electronic enclosures – IP‑rated housings requiring pressure compensation.
Flexible packaging – one‑way degassing for coffee, fermented foods, and MAP.
Automotive fluid systems – reliable overpressure relief in sealed modules.
| Factor | Benefit |
|---|---|
| Precision | Individually tested 5–8 mbar cracking ensures consistent actuation. |
| Protection | Unidirectional + multi‑layer sealing eliminates back‑diffusion risk. |
| Reliability | Proven performance across wide temperature and harsh environments. |
| Compliance | ISO9001, BRC, and food‑contact certifications available. |
| Flexibility | Full customisation – dimensions, materials, pressure settings. |
| Cost | High performance at lower cost vs. metallic alternatives. |
