Can you wire 120ac solenoid directly to Leader pump without a controller

Hi everyone, My question is regarding adding a solenoid valve ormotorized valve right after the pump. (Leader Ecojet 110)
I don’t have a main controller and I don’t really need one. This is the only valve I need which needs to be controlled (added assurance for preventing siphoning)
Thanks jeff
My pump is going to be on a timer, (Niwa grow hub). What I’m wondering is it possible to wire the solenoid directly to the leader pump internal wiring. That way when the timer turns the pump on, the valve also opens and vise versa.

My solenoids could be hard wired to the controller in series off the controller leads to energize a 110 VAC pump. Series prevents pump running if solenoid fails. Another thought for you.

Help abounds here. It will come.

as stated above yes but electrically it may be expressed as a parallel circuit energizing a N.C ( valve opens when energized) so if you are buying new verify its a N.C solenoid) or you will have problems The pump and solenoid electrically energize at the same time in parallel.
If this is commercial we could trick it out but this abviously comes with an expense. Simple is good most of the time
Keep in mind with solenoid vs motorized is opening time in sec. solenoid is almost instantanious and probably cheaper. For this application the solenoid may be a better choice.
Full disclosure above is in response to what i think you are wanting to accomplish.

It may be worth noting although we are talking about 2 way valves meaning 2 ports directional flow is important when it comes to opening and closing due to the position of the valve seat . If installed backwards you may have problems, I suspect most people knows what it cant hurt to double check the valve postion prior to commisioning or filling system for test. Should be a arrow indicator on valve for flow direction.

One last thing just in case it gets over looked . solenoid should be installed on discharge of the pump. ( Centrifigal pumps which i assume you are using most always preform best with the least amount of restriction on the suction side to prevent unneccasary drop in NPSH but this may be more than you are asking
