Deciding between these two industrial valves comes down to a simple question: do you need a complete control valve or a targeted replacement component? The Powers Process 593WM150STMS46RS Flowrite II Heavy Duty Bronze Control Valve 3-Wa represents the full-assembly route, while the NEW Power Process Controls 227-340 Valve & H. Water Seat is a low-cost replacement part. They sit at opposite ends of the price range, but each can be the right buy for the right job.
Quick verdict
If your project calls for a complete control valve, the Flowrite II is the more complete answer, even though it is listed as used. If you need a new valve-and-seat part and want to keep the cost low, the Power Process Controls 227-340 is the practical pick.

Where each product wins
Powers Flowrite II wins when you want a complete control valve assembly rather than a repair component. Its specific model number and full build give you the main piece of a control system instead of a single seat-and-valve part.
Power Process Controls 227-340 wins when you are replacing a valve-and-seat assembly and want a new part. It carries a much lower listed price than the Flowrite II and comes in new condition, so you are not starting with a used component.
Product notes
Powers Process 593WM150STMS46RS Flowrite II Heavy Duty Bronze Control Valve 3-Wa

The Flowrite II is the pick when you need a full control valve rather than a repair component. It has a heavy-duty bronze body and a specific model number, 593WM150STMS46RS, so you can match it to your system's requirements. The limitation is the used condition: this valve will need a careful inspection before installation, and you should confirm it meets your application. At USD 1,126.98, it is an investment in a complete assembly. That model number also gives you a clear reference when coordinating with a technician, and the bronze body is the foundation of the full assembly.
NEW Power Process Controls 227-340 Valve & H. Water Seat

Choose the 227-340 when you want a brand-new valve-and-seat component at a listed price of USD 19.98. MPN 227-340 gives you a clear part number to reference, and the new condition means you are not inheriting wear. The limitation is fit: this is a specific replacement component, and you should confirm the part number with an authorized dealer before buying. It is a replacement component rather than a complete control valve, so it suits repair work more than a full valve installation. If your system only needs a replacement seat-and-valve piece, this is a direct and low-cost route.
Final choice by use case
If your system already has a valve body and only needs a seat-and-valve part, the 227-340 is the logical buy. If you are assembling from scratch, the Flowrite II is the more complete starting point.
- Complete control valve: Choose the Powers Process Flowrite II if you need a full three-way mixing valve assembly for an installation that starts with the main valve.
- Low-cost replacement part: Choose the NEW Power Process Controls 227-340 Valve & H. Water Seat if you need a new valve-and-seat component and want to stay near the $20 mark after confirming fit.
