Need an industrial valve but can't decide between a complete valve assembly and a valve actuator? Here are two different answers: the Sinclair Collins SC2000M Process Control Valve L234-1301, 350 PSI, DN20 2-Way at USD 159.95, and the Johnson Controls MP823E .75 Stroke 9-13 PSI Process Control Valve Actuator at USD 66.35. One gives you the full manifold-ready, two-way valve; the other is a replacement actuator with a 0.75-inch stroke. The right pick depends on whether you're building the whole assembly or replacing just the actuator.
Quick Verdict
Start with the bigger question: do you need a valve or an actuator? If you need the complete process control valve, the Sinclair Collins SC2000M is the pick-it brings the valve body, cylinder actuator, position indicator, and DN20 manifold mounting together in one unit. If you only need the actuator, the Johnson Controls MP823E is the lower-listed-price route at USD 66.35.
Price and Specs at a Glance
| Attribute | Sinclair Collins SC2000M | Johnson Controls MP823E |
|---|---|---|
| Listed price | USD 159.95 | USD 66.35 |
| Price bar | ||
| What you're buying | Process control valve with position indicator | Process control valve actuator |
| Condition | New - Open box | Used |
| Brand | Parker Hannifin | Johnson Controls |
| Origin | United States | United States |
| Mounting/stroke details | DN20 manifold mounting, 1/2-inch ports | 0.75 stroke, 9-13 PSI |
The listed-price spread is USD 93.60. That gap buys you a complete valve assembly instead of a bare actuator, so it isn't just a question of price-it's a question of scope.
Where Each One Wins
Sinclair Collins SC2000M wins when you need the full assembly. The SC2000M is configured for two-way normally closed operation and is described for steam, hot or cold liquids, air, and inert gas. It includes a position indicator, a cylinder operator, and a 316L stainless steel body, with DN20 manifold mounting and 1/2-inch ports. For a one-part solution that connects into a manifold, this is the listed option to choose.
Johnson Controls MP823E wins when you need the actuator only. This is a used U.S.-made MP823E actuator with a 0.75 stroke and a 9-13 PSI operating range, listed at USD 66.35. If your project is replacing an MP823E actuator rather than buying a valve, you're getting the exact component type at a much lower listed price.
Product Notes
Sinclair Collins SC2000M Process Control Valve L234-1301, 350 PSI, DN20 2-Way
This is the full assembly at USD 159.95. It's positioned as a process control valve with position indicator, two-way normally closed operation, and compatibility with steam, hot or cold liquids, air, and inert gas. The construction includes a 316L stainless steel body and DN20 manifold mounting with 1/2-inch ports. Choose it when the job calls for the complete valve, not just an actuator. The trade-off is condition: it's open box with no retail packaging, with minor exterior wear and a few spots of light oxidation from storage. The valve itself is described as new, never used, but expect cosmetic signs of handling.
Johnson Controls MP823E .75 Stroke 9-13 PSI Process Control Valve Actuator
This is the component-level option at USD 66.35. It's a used Johnson Controls actuator with a 0.75 stroke and a 9-13 PSI operating range, made in the United States. It is not a valve body, so it won't cover a job where you need a manifold-mounted valve assembly. But when the need is specifically an MP823E actuator, this listed price is far below the complete valve and the used condition goes with the lower listed price. The gtin is stated as not applying, so don't expect a retail barcode on this unit.
Final Choice by Use Case
Need a manifold-ready, two-way process control valve for steam, liquids, air, or inert gas? Choose the Sinclair Collins SC2000M at USD 159.95. Need an MP823E actuator with 0.75 stroke in the 9-13 PSI range? Choose the Johnson Controls at USD 66.35. The deciding factor is the scope of the job.
