Choosing an industrial valve for a process line often comes down to how much specification you need versus what you can spend. Sometimes you need a valve with a known model, size, and port configuration to match an existing system. Other times you just need something workable without breaking the budget. This head-to-head compares two used control valves at opposite ends of the price range: the Powers Process 593WM150STMS46RS Flowrite II Heavy Duty Bronze Control Valve and the Burkert Process Actuator Control Valve.
Quick Verdict
If you need a fully specified heavy-duty control valve, the Powers Flowrite II is the clear pick. If you can work with a more general actuator control valve and want to keep your spend low, the Burkert is a far more affordable option-but you'll be buying it with visible shelf wear and less specification detail.
Comparison at a Glance
| Product | Price | Condition | Key Details |
|---|---|---|---|
| Powers Flowrite II 593WM150STMS46RS | $1,126.98 | Used | 3-way mixing, 1-1/2-inch heavy-duty bronze, model 593WM150STMS46RS |

Where Each Product Wins
Powers Flowrite II wins if your priority is a fully identified control valve with a known specification and heavy-duty construction. It is the choice when you have a specific installation in mind and need a valve that matches it exactly.
Burkert Actuator wins if your priority is keeping the upfront cost low and you have the flexibility to source a general-purpose actuator control valve. The price spread between the two is wide, and the Burkert is the more accessible option.
Product Notes
Powers Process 593WM150STMS46RS Flowrite II Heavy Duty Bronze Control Valve
This is the valve that leaves little to guesswork. It is a Flowrite II heavy-duty bronze control valve with a 3-way mixing configuration and a 1-1/2-inch port. The model number, 593WM150STMS46RS, is stated clearly, which is a strong advantage when you need to confirm compatibility with your process piping. The trade-off is price: at $1,126.98, it is the higher-priced option of the two, so it's an investment that makes sense when the specification is non-negotiable. The described capabilities are clear and concrete, making it a solid choice for buyers who value certainty over cost savings.
Burkert Process Actuator Control Valve
This Burkert offers a much lower entry point at $159.99. It is a process actuator control valve made in Germany, identified here as a general-purpose unit rather than a fully specified model. The condition note describes good condition but with shelf age wear and dirt and dust from storage, so expect to clean it before installation. If you have the technical flexibility to work with a broader valve category and want to stay close to the $160 price point, this is the value pick. Just be prepared to do the legwork to confirm it works for your process.
Final Choice by Use Case
Choose the Powers Flowrite II when you need a 3-way mixing control valve with a known model, heavy-duty bronze construction, and the confidence of a clearly identified part. Choose the Burkert Process Actuator Control Valve when budget is your main driver and you can verify whether a general purpose actuator valve will work in your setup.
