PROTECT YOUR CARGO TANKS OPTIMALLY WITH SUPERIOR HIGH-VELOCITY VALVES
Our sophisticated high-velocity valves challenge the status quo with their innovative mechanics, combining the magnetic Mini-Slip technology with weight activation. The advanced technology maintains the required exit gas velocity with controlled valve breathing, eliminating the danger of valve hammering. It ensures instant set point opening and facilitates rapid venting with an impressive two-second cycle time.
What’s more – each valve meets the highest international regulatory compliance of ISO 15364:2021 and ISO 16852:2016, offering utmost reliability and consistent performance.
With our high-velocity valves, you get safety, transparency and maximized operational capacity at every level.
BENEFITS OF HIGH-VELOCITY VALVE WITH MINI-SLIP TECHNOLOGY
- Close-to-zero VOC loss.
- Easily adjustable settings
- Non-oscillating design with frequency less than 0.5 Hz (ISO 15364:2021).
- Upgraded design for transporting hazardous cargo
- Teflon sealing ring with advanced sealing capabilities.
- Fully sealed, threaded top cover protecting the magnet from seawater.
- Improved seat and disc tolerances.
- Leakage rates below the ISO 15364:2016 recommended limits
- Option of pressure side valves with zero leakage
TRANSPORT METHANOL WITH UTMOST SAFETY
Designed with pressure vacuum release devices and flame arresters in one combined solution, our end-of-line high-velocity valves are a perfect fit for transporting methanol.
During the voyage, methanol fumes are vented from a tank, as required, and dispersed upwards through a high-speed vent, away from the vessel without any obstruction or leakage into storage or living areas, and finally released through the high-velocity valve. In case the fumes get ignited and turn into flames, the flame arrester prevents the passage of flames, protecting the vessel and crew from dangers of methanol leakage and explosion-related incidents.
Watch the Bay Valves High-Velocity Valve in action
The video shows Bay Valves’ high-velocity valve HI Jet ISO being tested by Institut für Sicherheitstechnik IBExU, an independent German notified body.
See how the valve operates according to the international fire testing standard ISO 16852 – completing an open and close cycle in 2 seconds, which corresponds to a frequency of 0.5 Hz.
This is a critical feature to avoid valve hammering, a common issue on cargo vessels, which is often overlooked. Valve hammering can be dangerous, often leading to vessel damage and other potential risks.
A Safety-First Approach
At Bay Valves, we put safety first in everything we do. And this extends to all our valve systems — from design and manufacturing to testing and maintenance — we ensure each one complies with the strictest international regulatory standards. Our high-velocity valves eliminate pressure surges upon opening, prevent flashback risks, and deploy high closing pressure to minimise cargo boil-off.
The high-speed vents further ensure the integrity and safety of the valve system.
What’s more – we ensure close-to-zero VOC loss with our Mini-Slip technology and improved valve design for all PV valves on ships, prioritising the highest levels of safety, protection and reliability in every cargo vessel.
