Which component of a safety valve ensures it seats properly?

The guides and bushings play a crucial role in the proper seating of a safety valve. Their primary function is to maintain the alignment of the valve disc or plug as it opens and closes. This alignment is essential for the valve to seat correctly against the valve seat and thereby create an effective seal when the valve is closed.

If the guides and bushings are worn or misaligned, the valve may not seat properly, leading to leaks or reduced efficacy in controlling pressure within the system, which can compromise safety. Therefore, the integrity of the guides and bushings is vital for ensuring that the valve operates effectively and safely.
