Choosing between two industrial valves usually comes down to the pipe you already have and the job the valve has to do. The two candidates here are built for very different parts of that job. One is a handwheel-operated globe valve; the other is a ball valve. The right pick depends on your line size, connection, and how you want to control flow.
Quick verdict
If your priority is precise throttling, the KITZ valve is the better match. If your system calls for a larger valve, the Spears valve is the one to buy. The comparison table below shows the exact sizes, connections, and ratings.
At a glance
| Decision point | KITZ Valve | Spears Valve |
| Listed price | USD 39.99 | USD 99.95 |
| Size | 1 inch | 3 inches |
| Connection | Female NPT threaded | Socket |
| Pressure rating | 200 WOG | 235 psi |
| Suitable media | Water, oil, gas | Water |
| Condition | New surplus | New open box |
Where each product wins
The KITZ valve's edge is controllability. The design is meant for gradual adjustments, which matters when you're throttling flow rather than just opening or closing a line. It also brings corrosion-resistant construction to systems where you want a valve that handles water, oil, or gas service.
The Spears valve's edge is capacity and simplicity. The socket connection and EPDM O-ring are practical details, and the valve is built for a larger line. This is the pick when you need a straightforward line rather than precisely throttled flow.
Product notes
KITZ Globe Valve
The KITZ is a new-surplus valve with a handwheel and a threaded body. Its 200 WOG rating is part of the spec to note. Keep the condition in mind: new-surplus items can show minor cosmetic marks from storage. If you need a working component rather than a display piece, that's a fair trade. The handwheel-driven design is the real reason to choose it-it lets you make smaller, more deliberate flow adjustments than a quick on/off valve. The limitation is that it's aimed at controlled flow, not fast shutoff in a large-diameter line. For a threaded setup where regulation matters, this is the one that deserves your attention.
Spears Ball Valve
This Spears is a new open-box valve made in the United States with an EPDM O-ring. No other parts or accessories are included with it, so you're getting the valve as shown-nothing extra. That makes it a practical pick if you already have the surrounding piping in place. The limitation is the open-box condition: it comes without a full retail package. If you need a straightforward shutoff and don't want to source extra hardware, this condition is the trade-off. The EPDM O-ring and U.S. origin are useful details to weigh, but the lack of included accessories is the main reason to plan your installation around what you see.
Final choice by use case
- For a 1-inch line where flow regulation matters, choose the KITZ.
- For a 3-inch line that needs a direct on/off valve, choose the Spears.
- If the 1-inch size works and the lower listed price is your tie-breaker, the KITZ is the straightforward pick.
