Quick verdict
Both of these act as process control valve actuators for industrial valve work, and both carry the same Johnson Controls MP823E model designation. They also line up on the same .75 stroke and 9-13 PSI spec, which means the functional spec you are looking at is the same for both. The price split is wide: USD 61.91 for one, USD 897.64 for the other. With that kind of absolute spread, the question is not whether the model fits, but whether you are willing to start with a used unit or pay for new condition.
Price and condition snapshot
| Readable unit | Listed price | Price comparison bar | Condition |
|---|---|---|---|
| Johnson Controls MP823E .75 Stroke 9-13 PSI Process Control Valve Actuator | USD 61.91 | Used | |
| Johnson Controls MP823E Process Control Valve Actuator | USD 897.64 | New |
Where each unit wins
Used MP823E: This version wins when the purchase decision is dominated by the listed price. It brings the MP823E model number and the .75 stroke / 9-13 PSI spec to the table at the lower end of the price spread. The trade-off is straightforward: you are choosing a used unit rather than a new one, and the listed attributes reflect that with a GTIN of Does Not Apply.
New MP823E: This version wins when new condition is non-negotiable. It is the same MP823E model and the same stroke / PSI spec, but it is listed as new. It also includes the explicit MPN MP823E, so the part identification is direct. The trade-off is the higher listed price.
Product notes
#### Johnson Controls MP823E .75 Stroke 9-13 PSI Process Control Valve Actuator
If the deciding factor is getting the MP823E spec while keeping the initial purchase price low, this used unit is the one to weigh. It shares the .75 stroke and 9-13 PSI range with the new unit, and it is identified as Model MP823E with a United States country of manufacture. The main limitation is condition: this is a used unit, not a new one, and it has a GTIN of Does Not Apply instead of an explicit manufacturer part number. The used condition is also the reason the listed price sits at the low end of the spread. Choose this unit when a previously owned actuator is acceptable and the lower listed price is more important than a never-used state.
#### Johnson Controls MP823E Process Control Valve Actuator
Choose this new unit when you specifically want a Johnson Controls MP823E Process Control Valve Actuator that has not been used. It is the same MP823E model and the same .75 stroke and 9-13 PSI spec as the used version, but it is listed as new. It also provides the MPN MP823E, which makes the part identification explicit and removes the need to rely on a GTIN. The limitation is the price: the new unit carries the high end of the listed price spread, so it makes sense only when new condition is a genuine project requirement. If your goal is to minimize the amount spent on the actuator, the used unit will be the more fitting choice.
Final choice by use case
If the decision is driven by the absolute price on the page, the used Johnson Controls MP823E is the one to choose: it delivers the same model number and the same .75 stroke / 9-13 PSI spec at the low end of the spread. If the decision is driven by condition and you want a new unit with an explicit MPN, the new Johnson Controls MP823E is the appropriate pick. The two units share the core MP823E identity, so the final call comes down to whether used condition is acceptable for your project.
