Powers Process Flowrite II Valve vs Power Process Controls 227-340 Seat: Which to Buy?

A complete control valve and a replacement seat serve very different jobs. This head-to-head compares the Powers Process Flowrite II and the Power Process Controls 227-340 seat to help you choose the right industrial valve part.

Last updated Aug 17, 2026

Choosing between industrial valves often means deciding between two very different jobs. Here, you have a complete control valve on one side and a replacement valve seat on the other. The Powers Process Flowrite II is a complete control valve priced at $1,220.98, while the Power Process Controls 227-340 is a valve and seat for an existing assembly priced at $19.98. Those prices put them at opposite ends of the industrial-valve range, so the right choice depends on whether your job requires a full valve or a service component.

Quick verdict

If your system needs a complete control valve, the Powers Process Flowrite II is the part that can handle that job. If you already have the valve and need the specific 227-340 seat to service it, the Power Process Controls 227-340 is the replacement component to consider. The two aren't interchangeable, so picking by price alone would be a mistake. The decision is less about which one is "better" and more about which part matches the work you're actually doing.

Product notes

Powers Process Flowrite II Control Valve (593WM150STMS46RS)

Powers Process 593WM150STMS46RS Flowrite II Control Valve 3-Way Mixing 1-1/2

This is the complete unit. It's a Flowrite II control valve with a three-way mixing design and a 1-1/2-inch connection, identified by model 593WM150STMS46RS. It also carries the Powers Process brand, which makes it easier to match when you're ordering a replacement for a Powers Process system. The main thing to weigh is condition: this valve is listed as used, so you'll want to confirm it's in acceptable shape for your system before installation. If your project calls for a full control valve rather than a component, this is the option that fits that need.

Power Process Controls 227-340 Valve & H. Water Seat

NEW Power Process Controls 227-340 Valve & H. Water Seat

This is a new valve and hot water seat from Power Process Controls. It's a replacement component, not a complete valve, and it carries the 227-340 part number. Because it's new, it hasn't been used in a prior installation, which is often what you want when servicing a valve. For maintenance work, a new seat can be exactly what you need. The main limitation is fit: only an authorized dealership can verify that this part works for your application. So while the 227-340 is a specific component, you should confirm it's the right seat for your valve before purchasing.

Final choice by use case

If you're installing or replacing a complete control valve, choose the Powers Process Flowrite II. If you're repairing a Power Process Controls valve and the 227-340 seat is the part you need, choose the Power Process Controls 227-340. Match the component to the job, and you'll have the right industrial valve part on hand.
