Hello. Plug valves are a category of valve that can be confusing. They are often used to control the flow for HVAC systems as on/off valves. The Honeywell V8043 or VC valve are like these. The plug is on an arm that rotates and moves a ball (plug) to block flow, or to allow it. A globe valve also has a plug in it that is moved up or down to block flow...but I call those globe valves, not plug valves. A check valve does work like a plug valve in that it has a round ball that can allow flow in one direction, and if the flow reverse, close off the flow (not always a ball, a check valve may have a diaphragm, disk, other means of stopping flow). The principal difference is that the plug valve is a control valve... actuated by a motor of some kind. It allows flow in one direction or stops it. The check valve is more passive, allowing flow in one direction, or moving when the water flow direction is reversed to prevent back-flow. Does that help?
Hello Carlos. Please send an email to ecccustomercare@honeywell.com, so we can discuss this. Include a part number such as vgf31em30 and my name in the email so it gets routed to me.
Natural or LP gas valves often use solenoid valves, like the V4046 or V4295, and some humidifiers use them to allow water to flow into the humidifier, like the 32001639-002. However we do not have solenoid valves for HVAC on/off water control. (at least not that I am aware of in North America)
Easiest and the most effective description of valves, especially for beginners. Thanks a ton David !
You made my day!
such info helps us infield when we come across practical problems.Thsnks
Ahhh! David, you are a movie star! My favorite part of course starts at 13:25. Great to see you at the show.
Thanks Kristen! Great seeing you as well!
Thank you
Good over view. Need higher level sizing of the actuators.
good
Thanks SIr
Thanks Sir for the video.
In your presentation I think there is a confusion between Plug valve and Chech valve. Could you please confirm?

Hello David Arneson, I would like to download this presentation, can I get if in pdf or even as MS Power Point version?

Hello I want down load
solenoid valve is exist in honeywell?
