It should be equivalent to the requirements for other valves, for reference.

For explosion protection of electrical equipment, self-acting control valves should not be used

Self-acting types are mechanical valves that rely on the medium and control elements to operate. Explosion protection only relates to electrical equipment. Currently, fire safety standards do not apply to self-acting pressure regulators, but rather to other types of valves.
