ASME Section VIII certified safety valves designed for oil & gas, chemical, and power industries. Direct from the factory – faster delivery, wholesale pricing, and complete OEM/ODM customization.
In high-pressure systems, a single overpressure event can lead to catastrophic downtime, safety hazards, and environmental fines. Yet many procurement teams still rely on suppliers that offer:
According to a 2025 industry report, 43% of unplanned shutdowns in refineries are linked to safety valve malfunctions. The average cost? $500k per day in lost production.
Founded in 2008, Ningjin Thriveon Valve Co., Ltd. has delivered over 1 million industrial valves to 40+ countries. Our safety valve line combines decades of engineering experience with China’s most efficient supply chain. Here’s what you get:

Case in point: A Texas-based petrochemical plant replaced their European-source safety valves with Thriveon’s ASME-compliant models and reduced per-unit cost by 37% while maintaining the same cycle life. Their first order of 200 valves shipped in 4 weeks.
Compliance is non-negotiable. Every safety valve shipped from Thriveon comes with a full material traceability certificate (MTC) and hydrostatic test report. We meet OSHA, EPA, and local jurisdictional requirements.
"We switched to Thriveon safety valves for our Midland facility. Their ASME-stamped valves passed third-party inspection on the first try. The cost savings allowed us to reinvest in additional safety systems. Highly recommend."
— Robert M., Procurement Director, Permian Resources (USA)
Per ASME definitions, a safety valve (used for compressible fluids – gas/steam) opens rapidly (pop action), while a relief valve (for liquids) opens proportionally to overpressure. Thriveon produces both types; our safety valve range is designed for steam, air, and gas applications with full lift at 3% overpressure.
Yes. Thriveon holds ASME Section VIII Division 1 certification with the ‘U’ stamp (certificate # ISSUED BY NB). All standard models are available with U-Stamp upon request. We also provide NB registration and capacity certification per API 520.

"We've been buying butterfly valves from Thriveon for two years. When we needed safety valves for a new compressor station, they designed a custom spring-loaded model that fit our exact set pressure. The documentation made our local inspector very happy. Pricing was 35% below our previous supplier."
— Carlos G., Maintenance Manager, Gas del Sur (Argentina)
"Thriveon helped us replace aging German safety valves in our steam system. Their team answered technical questions over the phone immediately. The valves arrived with ASME stamps and full test reports. Two years in operation, zero leaks."
— Sarah K., Plant Engineer, Nouryon (Netherlands)
"I was skeptical about Chinese suppliers for safety-critical equipment. Thriveon’s factory visit changed my mind – they have modern CNC machines, a certified calibration lab, and a dedicated R&D team. Our trial order of 50 safety valves for a water injection project performed flawlessly."
— Adeel R., Project Manager, Saudi Maintenance & Supply Co. (Saudi Arabia)
"Fastest lead time we’ve ever experienced. Other suppliers quoted 14 weeks; Thriveon delivered in 5 weeks. And the quality is outstanding – we passed API inspection on the first attempt. Highly recommended for anyone needing reliable safety valves with short delivery."
— John T., Supply Chain Director, Eagle Energy (USA)
"We use Thriveon’s safety valves in our fire suppression systems. Their team customized the outlet threading and set pressure for our specific foam concentrate. Excellent after-sales support – they even sent a replacement spring free of charge when we mis-specified the temperature range."
— Hideo M., Safety Engineer, Sumitomo Chemical (Japan)
