Preventing Crankcase Explosion in Marine Diesel Engines

If you manage a fleet of seafaring vessels or even a single ship, you know that ensuring the safety and security of your crew and the passengers or cargo you carry are of utmost importance. You have enough to worry about without wondering if – or when – you’ll face a potentially deadly crankcase explosion in the engine room of one of your ships.

That’s why Penn-Troy and its BICERA Valve division have been making the best in crankcase explosion relief valves for more than a half century. It’s also why we’ve never stopped working to bring you an even better valve.
Thousands of BICERA Legacy Valves are in use on marine diesel engines around the world today, protecting people, equipment and cargo.

Today, we’re proud to bring you the most effective marine flame arrestor available anywhere, ever: the New BICERA Sigma Valve. 


The shift to natural gas:

There’s never been a better time to switch to BICERA Valve.

As environmental regulations on the federal and international levels are spurring a shift from diesel to natural gas-powered marine engines, the new BICERA Sigma valve offers shipping lines and marine-engine manufacturers a strong incentive to consider the BICERA Sigma valve for preventing crankcase explosions on marine natural gas engines as well. Whether your vessels are powered by diesel or natural gas, there is no better flame arrestor to protect your crew, passengers and cargo than the BICERA Sigma valve.
