HS-ISO High Velocity Pressure Vacuum Valve
Non-Oscillating Performance. Reduced Emissions. Maximum Safety.
The HS-ISO is the first non-oscillating high velocity pressure vacuum valve combining the advantages of traditional weight-loaded valves with the precision of magnet-controlled technology without the typical drawbacks such as pressure surge, hammering, or unnecessary VOC emissions.
Designed for tanker applications requiring ISO15364 compliance, the HS-ISO ensures stable and controlled venting under demanding operational conditions.
Advanced Hybrid Valve Technology
Conventional weight-loaded valves can create pressure peaks during opening. Pure magnet valves may cause excessive blowdown and vapour loss.
- The HS-ISO combines both principles:
- Magnet-assisted opening control
- Weight-assisted closing
- Non-oscillating operation
- Reduced blowdown pressure
This ensures constant pressure control in the cargo tank while minimising vapour emissions and cargo loss.
Engineered for Tanker Safety
High exit velocity ensures safe gas dispersion away from deck areas, contributing to enhanced crew safety. The robust mechanical design ensures reliable performance even in demanding marine environments.
Operational and Environmental Benefits
- Reduced VOC emissions
- Lower cargo loss during voyage
- Stable pressure control
- No hammering or oscillation
- Long service intervals
- Fewer moving parts
The HS-ISO valve supports compliance with IMO regulations and relevant ISO standards, making it a future-proof solution for oil, chemical, and specialised tankers.
