Vacuum relief valves are critical components of tanks that need to stay in the right pressure range, such as water heater tanks. They prevent low-pressure conditions ultimately. If you want to buy one for a tank system, use this guide for a successful valve investment.

Make Sure Precise Performance is Provided 

Since the main role of a vacuum relief valve is to allow more air inside your pressurized tank to bring pressure levels up, you need this valve to work in a precise way consistently. It needs to open up at the right time, provide the right amount of air, and then close when it's supposed to.

To get all these actions to happen in a precise way every time, you need to be strategic with the vacuum relief valve you purchase. It's probably for the best to consult with a supplier and get some model recommendations. They'll know which valves can perform the best in the areas that were just mentioned.

Opt For a Protective Coating

You can find vacuum relief valves in a lot of durable materials, including aluminum and steel. However, if you want to enhance the durability of this valve even more and thus get more years of optimal use from it, then you might look for valves that have protective coatings.

For instance, you can get a valve that has a weatherproof coating and thus won't be as exposed to damaging conditions. You can subsequently avoid rust and other structural problems over the years with this valve solution.

Make Sure Seals Can be Replaced

An important aspect of a vacuum relief valve for pressurized tanks is the seals. They help this valve perform its role effectively but eventually, these seals will experience natural wear. That's okay if you get seals that have a replaceable design. Whenever severe wear has taken place, you can set up a new set and then get optimal performance out of this valve once again. 

Whereas if the seals weren't replaceable, you might have to find a completely different valve and thus spend more money than you otherwise would. So essentially, these replaceable seals can save you money.

If you want the ability to introduce air into piping systems for a tank in order to bring up its pressure levels, then you'll need a vacuum relief valve. Just make sure this valve performs great, can hold up, and has advantageous features.
