Stable opening, reliable sealing
High-speed breathable P/V valve is used for pressure and vacuum protection of the cargo hold ventilation system. EXSAFE adopts a wide body flow channel and hydrodynamic balance design to reduce the risk of oscillation and hammering under pressure fluctuation conditions.
Core features
- Non-oscillating, non-hammering design goals
- Metal to metal seal, sealing contact width 5.5 mm
- No need for magnets and periodic magnet replacement
- The pressure difference between opening and reseating is small, reducing unnecessary steam emissions
- FCD, WCB, SUS304, SUS316L materials are optional
Technical scope
The set pressure can be customized within the 5-100 kPa project range. The final model, diameter, material and pressure range are subject to project technical confirmation and valid certificate.
