🚀 Request Free Engineering ConsultancyFor procurement managers and plant operators in the chemical, oil & gas, and power generation sectors, a single overpressure event or valve failure can cascade into an operational and financial disaster. Relying on traditional supply chains for your pressure relief devices exposes you to five critical pain points:
A stuck or undersized relief valve can halt an entire production line. The average cost of unplanned downtime in the refining sector exceeds $50,000 per hour.
Non-certified valves violate OSHA PSM and ASME Section VIII standards. A single audit failure can result in massive fines or, worse, catastrophic injury.
Traditional suppliers require 12–20 weeks for custom-set ASME valves. To compensate, you stock excessive spares, tying up valuable CAPEX in idle inventory.
Broker markups, expedited shipping fees, and quality disputes with intermediaries inflate your total cost of ownership by 25% to 40%.
Buying from a distributor often means zero application engineering. Getting the wrong set pressure or material for your media (e.g., H₂S or cryogenic service) is a disaster waiting to happen.
Result: Increased total cost, higher risk, and constant firefighting. There is a better way.
Leveraging 15 years of global valve manufacturing expertise and a dedicated R&D team of senior engineers, Thriveon provides a complete range of high-quality pressure relief devices designed to meet the stringent demands of the American and European process industries. We are not just a supplier; we are your strategic sourcing partner for critical safety applications.
Every valve is backed by ASME Section VIII (UV Stamp), API 520/526, CE/PED, and ISO 9001:2015. Full material traceability and digital test reports included.
Download Certifications →Our integrated factory model (foundry to final assembly) allows us to ship custom ASME valves in 4–6 weeks—compared to the industry standard of 12–20 weeks.
By eliminating intermediaries, we offer a 15-25% cost advantage on equivalent ASME-certified safety valves without compromising on materials or testing.
Custom set pressures, specialized materials (316SS, Hastelloy C-276, Monel, Duplex), NACE MR0175 compliance, and custom end connections (flanged, SW, BW).
We offer live video witnessing of pop tests and seat leakage tests. You get 100% certainty before the valve leaves our facility.
Reduce vendor complexity. Alongside PRVs, we supply butterfly, gate, globe, and check valves—simplifying your procurement for major projects.

In short, a safety valve opens rapidly (pop action) and is typically used for compressible fluids like steam or gas. A relief valve opens proportionally to the increase in pressure and is used for liquids. Thriveon manufactures both types, including ASME Section VIII safety relief valves that can handle dual-service applications.
Yes. We are certified to manufacture and stamp safety valves per ASME Section VIII Division 1 (UV Stamp). Our quality system is also ISO 9001:2015 certified. We provide full capacity certification and documentation with every shipment.
For standard sizes and materials, our MOQ is just 2 pieces for engineering-to-order custom valves. For standard off-the-shelf relief valves, we can accommodate single-piece orders for urgent spares. We understand the need for flexibility in turnaround and project-based procurement.
Absolutely. We regularly supply pressure relief devices for sour service environments. We use materials that fully comply with NACE MR0175 / ISO 15156, including controlled hardness, Inconel X-750 springs, and appropriate trim materials.
We have extensive experience exporting to the USA and other English-speaking markets. We ship via air, sea, or express (DHL/FedEx) based on urgency. We handle all export documentation, including ASME Section VIII data reports, material certificates, and customs clearance support. Delivery to US ports or door-to-door is seamless.
Yes. For qualified projects and first-time buyers, we offer free sample valves (standard sizes) for qualification testing. You only pay for shipping. This allows you to verify our quality, documentation, and performance risk-free before committing to a bulk order.
Our engineering team specializes in custom solutions. We have successfully designed pilot-operated relief valves for complex systems with variable back pressure. Contact our engineering department with your process conditions (Flow rate, Set point, Back pressure, Media) and we will provide a technical proposal.
We offer a standard warranty of 18 months from the date of shipment or 12 months from the date of installation, whichever occurs first. This covers defects in materials and workmanship. We stand behind our manufacturing quality.
Don't let long lead times and high costs compromise your plant safety. Get factory-direct pricing on ASME certified pressure relief devices tailored to your exact needs.
