Penn-Troy is one of the only manufacturers that specializes in producing explosion relief valves and crankcase doors in a single cast, ready-to-attach unit to your engine’s exact specifications. This saves you costs by cutting manufacturing time and your engine assembly process in half. We can even source additional doors without attached valves to help you achieve a consistent appearance. Our two crankcase explosion relief valve models can be ordered as an integrated unit or separately.

Why Integrated?

1. Bolt-On Ready
Our no-hassle design comes fully assembled and makes it easy for operators to install the valve on the engine, eliminating the time and cost of training operators on handling, set up, testing and installation.

2. Customized to Match Existing Inspection Doors
We’ll utilize your original door design and modify it to seamlessly integrate with our valve. By simply adding an external housing to fabricated or cast doors, which moves the flame trap out, we can make room for the piston rods inside the crankcase.

3. Design Capabilities
We use SolidWorks for the design, modeling, rendering, FEA, CFD and can perform vibrational testing on the full unit.

4. Single Unit Design
In lieu of separate part numbers and inventory for valves and doors, we offer a simpler solution by combining all the components into a single cast unit.
