Quick Take
Choosing an industrial valve or actuator can feel like comparing two different product categories: the upfront cost range is wide, and so is the condition gap. The options here span from a used half-inch process control valve to a brand new actuator for process control, with an open-box stainless valve and a used 40 PSI valve in between. Conditions vary from used to new, and the listed price spread reflects that range. Your first decision is whether you need a complete valve, a replacement actuator, or a valve with a known media compatibility. The comparison below helps you match each option to its best use.
Listed Price Comparison
| Product | Price | Bar | Condition / Key Detail |
|---|---|---|---|
| Jamesbury V1SD1A3ACON Stabilflo 1/2\" Process Control Valve | USD 33.17 | Used | |
| Johnson Controls MP823E Process Control Valve Actuator | USD 897.64 | New actuator | |
| Process Control Valve 1\" Stainless A743 CF8M | USD 220.00 | New - Open box | |
| SINCLAIR COLLINS C293-030 PROCESS CONTROL VALVE C668-012 40PSI | USD 88.00 | Used |
The table shows the full listed price spread. The new actuator carries the highest price, while the used Jamesbury valve carries the lowest. The open-box stainless valve sits in the middle, and the used Sinclair Collins is just above the lowest.
Decision Matrix
| Your situation | Best match | Why |
|---|---|---|
| Need a valve for a 1/2-inch line with minimal outlay | Jamesbury Stabilflo | Used, lowest listed price |
| Need a new control valve actuator, not a valve body | Johnson Controls MP823E | New actuator |
| Need a stainless valve for water service with motorized operation | Process Control Valve 1\" Stainless A743 CF8M | New open box, suitable for water |
| Need a used valve for a 40 PSI application | Sinclair Collins C293-030 | Used, 40 PSI in the title |
Product Notes
Jamesbury V1SD1A3ACON Stabilflo 1/2\" Process Control Valve
The Jamesbury Stabilflo is a used process control valve with a 1/2-inch size, and its listed price is the lowest in this set. If your project needs a compact valve and you want to keep initial spend down, this is the direct path. The condition is used, so the trade-off is that you are buying a previously owned unit rather than a new or open-box item. Its country of manufacture is the United States, and the model name is Stabilflo. This is a complete valve, not an actuator, so factor the overall system into your planning.
Johnson Controls MP823E Process Control Valve Actuator
The Johnson Controls MP823E is the only true actuator in this group, and it is listed as new. If you have a process control valve body that needs a replacement actuator, this targets that need directly. The model name is MP823E, and the listed price is the highest in this set, so it represents a more substantial investment. The trade-off is that it is a component, not a complete valve assembly. The new condition gives you a fresh unit, but the higher listed price means this option is best when you know an actuator is exactly what you need.
Process Control Valve 1\" Stainless A743 CF8M
This 1-inch stainless valve in A743 CF8M material is listed as new open box, with a price in the middle of the group. It is pilot-operated with a pin-type controller, and its operation is listed as motorized, with water as the suitable media. If you are looking for a stainless valve for water service and want it to be newer than a used unit, this is a strong fit. The condition is open box, so you are getting a valve that is new but not in original sealed packaging. Some stainless couplings appear in the photos but are unrelated to the valve. The listed price is USD 220.00.
SINCLAIR COLLINS C293-030 PROCESS CONTROL VALVE C668-012 40PSI
The Sinclair Collins C293-030 is a used process control valve with a 40 PSI rating in its title. If you need a valve for a 40 PSI application and want to keep the cost lower than the stainless and actuator options, this used unit sits at USD 88.00. The model number C293-030 / C668-012 is clearly listed, and the condition is used. That used condition is the main limitation to weigh against the price. This is a valve body, not an actuator, so plan for the rest of the control loop accordingly.
Final Recommendation by Use Case
For a half-inch process control valve on a tight budget, the Jamesbury Stabilflo is the lowest-priced option. For a new actuator, the Johnson Controls MP823E is the only actuator in the group. For a stainless valve suited to water, the 1-inch A743 CF8M valve offers a new open-box condition. For a used 40 PSI valve, the Sinclair Collins C293-030 fits that pressure spec. Match your primary need to the product that addresses it directly.
