Because the engines do not need to control air volumes, they lack a butterfly valve in the intake tract.

The resilient butterfly valve, which uses the flexibility of rubber, has the lowest pressure rating.

A lug-style butterfly valve used in dead end service generally has a reduced pressure rating.

Engine speed is low but the butterfly valve is fully open.

Many diesel engines do not have butterfly valve throttles.

External wastegates can also use a butterfly valve, though that is far more rare.

First, two discrete intake runners with different length are employed, and a butterfly valve can close the short path.

But a diesel engine does not have a butterfly valve to limit air on the intake side.

Major representatives of this type are butterfly valves and ball valves.

Their main products are boilers, butterfly valves, turbines, and pressure vessels.
