Opinions on B&G Snap Zone Valve

Anyone has any experience with this B&G zone valve?

I like the shape design etc, and the unions.
I'm curious about the wear of the actuator, and the wear of the plunger.
I don't like rubber shutoffs, they don't last as much as ball valves.

Any experience in the audience?
Thanks in advance

Never used one.

IMHO the Taco Sentry are the best designed.

Just to be clear, Caleffi components all have a 2 year warranty, not 1 as the chart indicates.

The Z-one zone valve has a 5 year warranty if installed with Caleffi Z-one relay panel.

Odd that the comparison doesn't compare other thermal electric style? I think all those brands offer one?

The Caleffi 6767 checks all the boxes has a 5.6 Cv, manual open, and a wide selection of connection tailpieces.

Thermo-electric are common on hydronic manifolds and are commonly used for zoning where silent operation is desired.
Most thermal actuators are 250 mA, so you can get up to 12 on a 40 Va transformer.

Thanks guys,

I'm looking to install this in a building.
Less excited about manual option, because if it's easy then anyone can turn on anytime and leave it on, and most of these can't be closed electrically if opened manually I believe.

Any zone valve recommendation with this type of requirement in mind?

The TwisTop does release when powered up, just so you know.

I suspect the B&G valve works just fine, low power draw, quality brass construction.
