Choosing between a complete process control valve and a separate actuator is a common decision in industrial valve work. You need to know whether you are replacing a full valve body or just the component that moves it. Two very different listings illustrate the tradeoff: the Schrader Bellows Sinclair-collins C064-4002 Process Control Valve 1in NPT and the Johnson Controls MP823E .75 Stroke 9-13 PSI Process Control Valve Actuator.
Quick verdict
If you need a complete 1-inch threaded valve that operates pneumatically and is made of bronze, the Schrader Bellows C064-4002 is the direct answer. It is listed at USD 664.70 and arrives in new open-box condition. If you already have a valve body and only need the actuator with a .75-inch stroke and 9-13 PSI range, the Johnson Controls MP823E is the focused, far lower-priced option at USD 66.35, though it is used. The listed price difference is substantial-roughly $598 between the two-so the right choice depends on what is actually missing from your setup.
Comparison at a glance
| Product | Listed price | Price bar | Key attributes |
|---|---|---|---|
| Schrader Bellows Sinclair-collins C064-4002 | USD 664.70 | Pneumatic, bronze, threaded, new open box | |
| Johnson Controls MP823E | USD 66.35 | .75 stroke, 9-13 PSI, used, made in USA |
The bar chart makes the price spread obvious: the actuator listing sits at roughly one-tenth of the valve listing. But the products are not interchangeable. The C064-4002 is a full valve; the MP823E is an actuator meant to drive a valve.
Where each product wins
Schrader Bellows Sinclair-collins C064-4002 wins when the job calls for the valve itself. The title specifies a 1-inch NPT process control valve, and the attributes confirm a threaded bronze body with pneumatic actuation. The new open-box condition adds to its appeal if you want a valve that has not been previously installed.
Johnson Controls MP823E wins when you need a replacement actuator with a defined stroke and pressure range. The title calls out .75 stroke and 9-13 PSI, and the manufacturer is Johnson Controls. It is also the more economical choice by a wide margin, which matters if the valve body is already in place.
Each product has a clear limit. The C064-4002 is a much larger investment, and the MP823E is a used component, not a brand-new full valve.
Product notes
Schrader Bellows Sinclair-collins C064-4002 Process Control Valve 1in Npt
This listing leads with a complete process control valve in a 1-inch NPT size. The attributes specify pneumatic actuation and a bronze material, plus a threaded mounting type. Because it is labeled new open box, you are looking at an unused valve that has had its original packaging opened. The listed price is USD 664.70, the higher end of this head-to-head. Choose this product when your system needs the valve body itself and the specification matches a 1-inch NPT threaded bronze pneumatic valve. The limitation is the price: it is a significant outlay compared to the actuator-only listing.
Johnson Controls MP823E .75 Stroke 9-13 PSI Process Control Valve Actuator
The Johnson Controls MP823E is explicitly an actuator, not a complete valve. The title identifies a .75 stroke and a 9-13 PSI operating range, and the attributes confirm it is used and made in the United States. At USD 66.35, it offers a much lower listed price than the Schrader Bellows valve. This is the right direction if you need to replace an actuator on an existing process control valve and the stroke and PSI specs line up. The limitation is the used condition, which introduces normal wear considerations, and the fact that it does not include the valve body.
Final choice by use case
If you are building or repairing a line where the valve is missing and you need a 1-inch NPT threaded bronze pneumatic unit, the Schrader Bellows Sinclair-collins C064-4002 is the more complete purchase. If you already own the valve body and only the actuator needs replacing, the Johnson Controls MP823E matches that need at a much lower listed price. Weigh the new open-box condition and full valve assembly of the higher-priced listing against the used actuator and substantial price gap of the lower-priced listing. Your specific missing part will determine which one is the correct buy.
