The ATL Discriminator Vent Valve For Custom Top Plate provides safe fuel cell venting with integrated rollover protection for ATL custom top plates PL-BG-021 and PL-BG-022. It bolts directly to the threaded inserts on the top plate and uses a dual ball discrimination system with stainless steel and polymer balls to distinguish vapour from fluid while automatically sealing the vent during vehicle inversion to prevent fuel loss.
Discover the key features of this discriminator vent valve:
- Direct Top Plate Fitment: Designed specifically for ATL custom top plate part numbers PL-BG-021 and PL-BG-022, this valve bolts directly to the integrated threaded inserts which simplifies installation and provides a secure connection for reliable fuel cell venting.
- Dual Ball Discrimination System: The internal valve assembly uses one stainless steel ball and one polymer ball to distinguish between fuel vapour and liquid fuel, allowing normal venting during operation while rapidly sealing the outlet when inverted to reduce the risk of fuel spillage during a rollover incident.
- Rollover Leak Protection: Engineered to close the vent path when the vehicle overturns, the valve helps maintain total leak protection while still protecting the fuel cell from vacuum build-up or excessive internal pressure during normal operation.
- Anodised Aluminium Valve Body: Manufactured from lightweight aluminium with a corrosion-resistant anodised finish, the valve body provides durability in demanding environments and helps resist degradation caused by fuel vapour, moisture and general exposure within the fuel system.
- 25mm Hose Compatibility: Designed to accept 25mm (1”) bore vent hose, the valve integrates easily into larger capacity vent systems and supports efficient airflow management within the fuel cell setup.
This vent valve helps maintain stable fuel cell pressure while reducing the risk of fuel escape during a rollover situation. Its direct-fit design and durable anodised aluminium construction make it a practical addition to your fuel system setup where secure venting and leak protection are required. Adding the correct vent protection hardware to your fuel cell installation can help support safer and more reliable vehicle operation during demanding use.
