Is this valve reef safe? DIY Reef Genesis Auto Water Changer

[Rundmc2016]

I missed my chance to buy it, so I'm going to diy it. Any knowledgeable engineers out there know if this valve is reef safe?

https://wicvalve.com/3-4-Inch-Plastic-Zero-Differential-Electric-Solenoid-Valve-2PCG-3-4-D.htm

Body Material: PA66 Nylon Plastic

Seal Material: NBR (Buna N) Diaphragm & Plunger Tip

It looks like the body is nylon, will this crack/become brittle with repeated exposure to salt water?

Seal is made out of nitrile, so I think that's reef safe?

Other options I looked at were the anticorrosion solenoid on the same website but their rep said it needed a minimum pressure of 5psi to be safe to open and I checked out an actuated ball valve from another site that was close to $140.

It looks like the wetted surfaces would be OK

Thank you!

This one specifies safe for saltwater but it is more expensive.

Yeah, that's the one I looked at originally, but the rep from the company said that it needs maybe a 5psi opening pressure to work properly which won't work with the gravity feed for a Genesis diy.

I got a reply from the manufacturer.


"Thank you for your inquiry. This 2PCG series valve is a diaphragm type, the liquid or salt water will contact the metal parts such as spring and plunger inside the armature tube. Therefore, it is not recommended for salt water application."

So that's a no go.

The valve shown xr33, will stay where it is during power failure. It requires power to move in either direction. So if you are topping off and power fails, valve stays open.

Battery backup.

I contacted this company and they suggested I buy that and the XR22 module and swap so that it actuates closed automatically.
