Many imported regulators take 12‑20 weeks. That means delayed projects and lost revenue. You need a supplier who ships in 4‑6 weeks.
Low‑cost regulators often fail within 6 months, causing frequent replacements and production losses. High quality should not mean premium prices.
Without proper CE, CRN, or ASME certifications, your equipment risks non‑compliance. You need a partner who understands global standards.
With over 15 years in valve and regulator manufacturing, we deliver first‑stage regulators that combine rugged construction, precision control, and rapid delivery – all while meeting international certifications.

Custom designs for oxygen, hydrogen, and high‑purity applications available.
A first stage regulator reduces high inlet pressure (e.g., cylinder pressure up to 300 bar) to a stable intermediate pressure, typically 5‑15 bar. The second stage further reduces it to working pressure. First stage regulators are critical for systems with long pipe runs or high flow demands, such as industrial gas distribution.
Absolutely. We offer adjustable spring ranges from 0.5 bar to 50 bar as standard. Connections include NPT, BSP, SAE, flanged, and custom dimensions. For OEM projects, we can design the regulator body and internal trim to your exact specifications. Minimum order quantity for custom: 100 pieces.
All standard models are ISO 9001:2015 certified, CE marked, and RoHS compliant. For North America, we can provide CRN registration and ASME B31.3 compliance upon request. Material certificates (EN 10204 3.1) are included with every shipment.
Our standard lead time is 4‑6 weeks from order confirmation. For urgent requirements, we offer an express service (2‑3 weeks) for a small surcharge. Shipping terms: EXW, FOB Tianjin, or CIF to your port.

Senior Process Engineer, North Carolina, USA
"We’ve been using Thriveon’s first stage regulators in our nitrogen distribution skids for over a year. Zero failures, rock‑steady pressure. Their shipping time beat our previous supplier by 6 weeks. Highly recommend for any industrial gas application."
Procurement Manager, Ontario, Canada
"We needed a custom first stage regulator for a high‑flow hydrogen panel. Thriveon’s engineering team responded within 24 hours and delivered prototypes in 10 days. The final product met all specs and saved us 35% compared to our previous supplier. The only minor was the initial documentation, but they fixed it quickly."
Maintenance Supervisor, Lima, Peru
"Excellent quality for the price. We switched from a well‑known European brand to Thriveon for our LPG tank farm. After 6 months of operation, the regulators show no signs of wear. The local agent provided great support. Will order again for our expansion."
Supply Chain Director, Saudi Arabia
"Thriveon has been our strategic partner for two years. Their first stage regulators comply with Saudi Aramco standards. Delivery is always on time, and the quality remains consistent. We appreciate their transparency and willingness to customize."
Technical Director, Munich, Germany
"I was skeptical about Chinese regulators, but Thriveon proved me wrong. We tested their regulator against a German equivalent and found comparable performance. The price difference allowed us to invest in additional safety systems. Good support and fast responses."
