Will this pressure switch replace a DeVilbis switch # Z-D24918, 240 volt single phase?

No! Yours is a single stage, and the new one is a two stage. Much higher pressure. Your compressor is not rated that high. Will cause damage and possible injury. The safety valve on a single stage unit is preset to release at 125psi. That switch is rated at 135 to 175psi.

I don't know. The replacement had the switch in the same position as the original so I just installed it and it worked fine.

No, this is a single port switch, you need a 4 port switch, you can tell by looking at the bottom. Your switch needs 4 places where you can run pipes into for your regulator, Safety valve, gauge, and connector.There are plenty of 4 port pressure switches on Amazon. Good luck to you. Bob

I'm not sure. I had an electrician install these switches for me. I can only tell you the switch works great!

Jim, it might. what I'd do is remove this switch and have someone check it with a VOM (volt/ohm meter). If the switch is bad (it was in mine) chances are good it will cure your problem. Five bucks to save a $100+ service call is worth testing it. Good luck, Ed

No. It is rated for 120 volt single phase. You would have to reduce the 240 volt to 120 volts.

Not really sure; suggest checking with a licensed electrician. I am using this switch as a replacement to an identical one that controlled my 1hp pool pump, a use that this switch was primarily designed for.

I used brass airbrake fittings and airbrake tubing to replumb from the compressor head to the manifold, I don't think the voltage will be a problem, its just a matter if the replacement valve will fit in the place of the original. Much better switch than the what sears offers

The switch has two sets of contacts. You can use a single set of contacts for 120v or both sets for 240. It has a ground lug on the body. It is meant for simple 3 wire (2 wires with ground) pump. It's just a water pressure operated relay. Be sure to check and adjust the actual pressure it's operating at, I had to. The pressure number on the box is just the factory pre-set.

It should as it is a 3 to 1 switch. Unfortunately I don't have a way to test that configuration.

I believe it should work --- if not directly, then by using the ground, neutral, and single "hot" wire with the pressure switch to activate a relay controlling the 240 volts. (I am assuming the 240 consists of 4 wires --- two "hots", one neutral, and one ground. If this is not so, then disregard my comments.) Square D offers several models with specified pre-set on/off points. Their switches are easy enough to "tune" to your particular needs. Some models include extra-easy "external" adjusters. Within reason, you can raise or lower the on/off points together or tune them individually. Good luck; I think you can do it.

Sorry, I don't know the answer on that. I installed it in a Craftsman drill press after carefully measuring the old switch.

Unfortunatley, I have no idea.. I would think if you had an electric start before, this switch would work as a replacement. What I did find out is there are two sizes.. FOr the 9.9 I would by the smaller of the two switchs. Just so to can ensure you don't run into any space limitations when you preform the install.

I'm not sure, this switch didn't end up working I sent it back and went to local junk yard

My old one was a GT912 and my wife's was one we threw away (3 button "T" shaped unit) and this unit works very well. I believe if your old unit was an 8 or 12 dip switch type it should work. If you are a prime member, it can be returned for free.

I am not familiar with your model number, pull out the old switch and compare, if the look alike most likely it will fit, these companies use interchangeable parts for the part. you may also ask the seller.

I'd check out this model instead, it's a 40/60 unit - Square D by Schneider Electric FSG2J24CP 40-60 PSI Pumptrol Water Pressure Switch
