For procurement managers and plant operators who demand ASME-compliant, corrosion-resistant relief valves: our SRV Series delivers精准 cracking at ±3% set pressure, ships in 10-15 working days, and cuts total cost of ownership by 28% vs. premium European brands.
Trusted by 40+ buyers in USA, Saudi Arabia, South Africa & Italy
Every overpressure event that goes unrelieved — or is relieved late — eats into your bottom line. Here's what our customers told us before switching to Thriveon:
You don't need a cheaper valve. You need a stainless steel safety relief valve that works right the first time, every time — with full traceability and global certification.
Our SRV Series is built from 316L/304 stainless steel with PTFE or metal seats, designed for steam, chemical, cryogenic, and high-purity applications. Every valve is individually set and tested on our calibrated test benches.
Precision-ground spring and guided disc ensure repeatable pop action at set pressure — no chatter, no simmer.
316L/304 SS with MTR (Mill Test Report) included. Compliant with NACE MR0175 for sour service.
Third-party certified by TÜV and SGS. NB stamp available for USA projects.
Standard set pressures ship in 10 days. Custom set pressures (any value from 10 to 600 psi) ship in 15 days.
Need a special flange, end connection (BW/SW/Threaded), or cryogenic bonnet? Our engineers deliver custom designs in 5-7 days.
Same or better performance at a significantly lower landed cost — validated by 40+ active buyers in the USA.

* All valves are 100% factory tested and supplied with individual test certificate.
A stainless steel safety relief valve is specifically designed for corrosive, high-purity, or cryogenic environments. The 304/316L body provides superior corrosion resistance, while the seat materials (PTFE/PCTFE) offer chemical inertness. Standard carbon steel valves cannot handle acidic media or steam with high chloride content.
Our SRV series is ASME Section VIII certified with UV/UD stamp available. We also provide CRN registration for Canada. All valves are manufactured under ISO 9001:2015 and can be third-party inspected by SGS, TÜV, or BV upon request.
Yes. We offer any set pressure between 10 and 600 psi (0.7–41 bar). Standard values ship in 10 days; custom set pressures ship in 15 working days. Each valve is individually set and certified on our calibrated test bench.
Our MOQ is 1 piece for standard sizes (½" to 2"). For larger sizes (2½" to 8"), MOQ is 2 pieces. We understand that procurement teams often need a single valve for a critical application — we accommodate that.
We ship via FedEx / DHL / UPS for small volumes (5-7 days door-to-door) and via sea freight (FOB/CIF) for larger orders. For USA buyers, we offer prepaid duty and brokerage options. Shipping cost is typically 60-70% lower than shipping from Europe.
Yes. We offer free samples for qualified buyers (you pay only shipping). Test the SRV valve in your application for 30 days. If it doesn't meet your performance requirements, we'll refund the product cost — no questions asked.
We provide a 5-year warranty against manufacturing defects. Our engineering team offers free technical support via email, WhatsApp, or video call. If a valve fails due to manufacturing defect, we replace it at no cost — including shipping.
Simply visit our contact page or email info@thriveonvalve.com with your set pressure, media, end connection, and quantity. We'll respond with a detailed quotation within 24 hours on business days.
🔥 Limited-time offer: Free test report with every first order. First 20 new clients in March 2026 receive free priority shipping.
"Thriveon's SRV valve is a direct replacement for our legacy 316L relief valves. Same footprint, better performance, and 40% cost savings. We've placed 3 repeat orders this year."
"The technical documentation was flawless. Full MTR, CE declaration, and ASME data sheets — our auditor accepted everything without questions. Fast delivery too."
"We needed a custom set pressure of 28 psi for a special reactor. Thriveon delivered a perfectly adjusted valve in 11 days. The PTFE seat seals bubble-tight at 90% of set pressure."
"I compared their SRV against a major German brand side-by-side. Cracking pressure, reseat pressure, and leakage rate were virtually identical. But Thriveon's valve cost 1/3 less and shipped in 2 weeks."
"Excellent communication from the engineering team. They helped me select the right spring and seat material for our high-temperature steam application. Valve arrived with full test report."
