Need to Replace a Safety Valve?
Whether your valve failed a pop test, is leaking, corroded, or simply due for replacement — you don’t need to buy the same brand. Safety valves are interchangeable across manufacturers as long as the key specifications match. We’ll help you find the right Aquatrol replacement.
How It Works — 3 Simple Steps
Step 1: Upload Your Nameplate Photo
Every safety valve has a metal nameplate stamped with its specifications. Snap a photo with your phone and upload it using the form below. Don’t worry if it’s hard to read — our team handles these every day.
Step 2: We Identify the Replacement
Our engineers read your nameplate data and match it to the correct Aquatrol replacement valve — same specs, same fit. We verify all 5 critical attributes so you can order with confidence.
Step 3: Get Your Quote
We’ll email you the exact Aquatrol part number, pricing, and availability — usually within one business day. Most valves ship next business day with free shipping on orders over $500.
The 5 Things That Must Match for a Replacement Valve
Safety and relief valves are commoditized by specifications — brand is secondary. When replacing any valve, these attributes must match or exceed the original:
| Specification | Why It Matters | Where to Find It |
|---|---|---|
| ASME Code Section | Legal compliance — Section I (fired), IV (low-pressure), VIII (unfired) | Stamped on nameplate (V, HV, UV) |
| Set Pressure | Must not exceed vessel MAWP; typically operating pressure + 10% | Stamped on nameplate in PSI |
| Rated Capacity | Replacement must meet or exceed original (lbs/hr, SCFM, GPM) | Stamped on nameplate or catalog data |
| Inlet/Outlet Size & Type | Physical fit — NPT, flanged (150#, 300#), etc. | Stamped on nameplate or measure connections |
| Service Medium | Steam, air/gas, liquid — affects internals and capacity calculations | Stamped on nameplate or known from application |
Don’t have all this information? That’s exactly why we offer the nameplate photo service. Just upload a photo and we’ll pull the specs for you.
