Should You Specify a 24Vdc Solenoid Valve on the Inlet to a Day Tank?

December 9, 2020 by David Hurtado

Every year, I hear of a few instances where the factory-supplied solenoid valve on a day tank inlet is changed from an AC-powered model to a DC-powered model. Is a solenoid valve installed on the day tank inlet required to be DC powered?

I am a novice on fuel systems and needed help with a detail, David jumped in and gave me direction and assistance. Thanks David

I was very impressed the first time I dealt with David. I was recommended to David’s company by our Cummins sales representative, and David helped me thru my first fuel delivery system project for a Florida Assisted Living Facility. He does not just send general cut sheets of systems, … but details such as pump HP values, cables sizes, fuel piping sizes, sensor requirements, etc. I would recommend him highly to anyone struggling with fuel system design.

I was introduced to David by a coworker who insisted I speak with him for a fuel project design. It has been the best advice given to me. David is a fountain of knowledge and is more than willing to help and provide service. He has been an invaluable source of information for me.

I recently completed a fuel oil system design associated with (2) 2.5 MW emergency standby generators and worked closely with David for equipment design support associated with bulk storage tanks, day tanks, pump skids, filtration skids, fueling ports and controls. It was the first time that I worked with David and found the experience to be nothing short of excellent. I appreciated David's expertise and advice provided in selecting equipment and drilling down into details. David was always very responsive and went out of his way to make sure I had everything needed to complete my work and to answer all my questions during and after business hours. It's nice to work with folks that understand the equipment they represent and have a passion for the finer details. David has an excellent understanding of the equipment and was very enjoyable to work with. I look forward to working with David on our next project.
