Industrial Valves Guide: Compare 4 Process Control Valve Actuators, Coils, and Valve Bodies

Compare four industrial valve options: a used Johnson Controls MP823E at $61.91, a new MP823E at $897.64, a Powers 430 replacement coil, and a 1-inch stainless valve.

Last updated Aug 17, 2026

Quick take

When you are buying for an industrial valve setup, the first question is what you actually need: the actuator that moves the valve, the valve body itself, or a small internal replacement part. This set of four products spans all three. Two are Johnson Controls MP823E actuators, one is a Powers Series 430 replacement coil, and one is a 1-inch stainless process control valve. Start by matching the part to the gap in your system, then weigh condition and listed price. The listed-price range is wide, but that gap is not the whole story: the two actuators share a model name but not condition, and the coil and valve body solve different problems entirely.

Product notes

Johnson Controls MP823E .75 Stroke 9-13 PSI Process Control Valve Actuator

Johnson Controls MP823E .75 Stroke 9-13 PSI Process Control Valve Actuator

This is a used Johnson Controls MP823E actuator with a 0.75-inch stroke and a 9-13 PSI range. Choose it when the actuator model matches your setup and the lowest listed price in this set is your priority. The used condition is the main trade-off compared with the new MP823E. It is listed as manufactured in the United States, and the model number is MP823E. If your project can work with a pre-owned unit, this is the direct route to that model at the lowest listed price.

Johnson Controls MP823E Process Control Valve Actuator

Johnson Controls MP823E Process Control Valve Actuator

This is a new MP823E actuator in the same 0.75-inch stroke and 9-13 PSI family as the used version. Choose it when you want a new unit and are comfortable with a higher listed price. It is an actuator rather than a complete valve assembly, so it is the motion-control component of a larger valve setup. This is the direct new counterpart to the used MP823E in this set.

NEW POWERS PROCESS CONTROL VALVE SERIES 430, # 432 REPLACEMENT PART COIL

NEW POWERS PROCESS CONTROL VALVE SERIES 430, # 432 REPLACEMENT PART COIL

This is a Powers Process Controls replacement coil for a Series 430 Hydroguard 432 mixing valve, with part number 432-1065. It is listed as New - Open box. Choose it for a repair that needs a 430-series coil instead of a complete valve or actuator. The model number 430 and part number 432-1065 give a concrete reference for matching. Since it is a coil part rather than a full control valve, the scope of the project should already be clear: this replaces a coil, not the whole valve assembly.

Process Control Valve 1\" Stainless A743 CF8M

Process Control Valve 1" Stainless A743 CF8M

This is a 1-inch stainless A743 CF8M valve listed as New - Open box. It is rated at 1500 PSI CWP and identified as pilot-operated with a pin-type controller and motorized operation. Choose it when the valve body is the missing piece and you already have actuation or a controller in mind for the setup. The brand is listed as Research, so matching the valve to the right companion parts is part of the buyer's job. It represents the valve-body route in this set, distinct from the actuator and coil options.

Final recommendation by use case

  • If your project needs the MP823E actuator and you want the lowest listed price, choose the Johnson Controls MP823E .75 Stroke 9-13 PSI Process Control Valve Actuator.
  • If your project calls for the MP823E actuator and you prefer the higher-listed-price variant, choose the Johnson Controls MP823E Process Control Valve Actuator.
  • If you are repairing a Powers 430-series mixing-valve coil, choose the NEW POWERS PROCESS CONTROL VALVE SERIES 430, # 432 REPLACEMENT PART COIL.
  • If you need a 1-inch stainless valve body for a motorized control setup, choose the Process Control Valve 1\" Stainless A743 CF8M.
