Just because you can get shit done does not mean it is okay for managers to dump work on you where others are failing to pull their weight. You will burn out and you will be resentful of those exploiting you.
Also with regards to monetary value, ask for the raises regularly and prove that your work leads to said results. You should be getting the maximum rewards and having your salary adjusted based on the competitive market rate. Apply regularly to remind your employer who you want to remain "loyal" to that they can lose you if they aren't keeping up monetarily.
There are very few people in the world who look out for your wellbeing if you are "loyal". They will not help make space for when you need to take time off, they will not advocate for your promotions/career growth if you're in a crucial role, they will not see the disparity of how much value you bring versus how much you're rewarded.
You have to advocate for all this yourself. Be loyal to yourself first.
