Question: 1 / 400

If a valve has a 30 degree face, then the seat would be:

30 degrees

When a valve has a 30-degree face, the corresponding seat should also have a 30-degree angle. This is because for valves to seal properly, the face of the valve and the seat must match and make full contact. If the angles do not match, the valve will not seal correctly, resulting in leaks or inefficiencies in the system. Therefore, the correct answer is A - 30 degrees.

Choices B, C, and D are incorrect because they suggest angles that do not match the 30-degree face of the valve, leading to improper sealing and potential issues within the system.
