Bicera Explosion Relief Valves

Bicera Valves on engine

Everyday, you’re hard at work, trying to deliver for your customers. And while you work, you’re trusting your equipment to work hard for you.

You pay attention to detail, prioritize safety, comply with regulations and ensure that your team is following industry best practices. But often, it’s the smallest things, the things you can’t see, that combine to create the biggest issues.

When the oxygen, heat, and fuel in your engine collide under the right – or, in this case, wrong – conditions, that can lead to a buildup of highly combustible vapors inside the crankcase that, with a source of ignition, can result in a potentially deadly and damaging explosion.

That’s why BICERA has been making the best in explosion venting protection to help ensure the safety of people and property for well over a half century.
