You need precise flow control in your process line, but standard butterfly valves were never designed for continuous throttling. The result? Unplanned downtime, wasted product, and budget overruns.
➡ You don't need just any butterfly valve — you need a throttle butterfly valve engineered for precise modulation.
Designed with a linearized disc profile and low-torque seat, our valve gives you predictable, repeatable throttling from 10° to 70° opening — just like a control valve, at a fraction of the price.
Thanks to our precision-machined disc and gearbox interface, you get consistent Cv values every cycle. No drift, no surprises.
Patented disc edge profile reduces pressure drop across the disc, minimizing cavitation and noise — even at 40% opening.
7–15 days for standard sizes (2″–24″). Express service available for urgent orders. We keep popular sizes in stock.
Need a special disc coating? A custom flange drilling? Our engineering team modifies the design to your exact process requirements.
ISO 9001, CE/PED, RoHS, and API 609 in progress. Full documentation package provided with every shipment.
Compared to European or American control valves, our throttle butterfly valve delivers the same modulating performance at significantly lower cost — including shipping and duties.

A standard butterfly valve is designed for on/off isolation — fully open or fully closed. A throttle butterfly valve, on the other hand, has a specially profiled disc and seat that allows precise flow modulation across a range of opening angles (typically 10° to 70°). It provides predictable Cv values, low cavitation, and stable pressure control, making it suitable for regulating flow, pressure, or temperature in continuous processes.
Yes, in many applications our TBV-700 series can replace a traditional globe-style control valve at 30–50% lower cost. It works best for moderate pressure drops and where quick, repeatable positioning is needed. For severe service (very high ΔP, erosive media, or extreme temperatures), we can recommend metal-seated or lined configurations. Send your process data for a free sizing report.
For standard sizes (2″ to 12″) with pneumatic actuator and positioner, our lead time is 7–15 working days. For larger sizes (14″ to 24″) or special materials (Duplex, Hastelloy), lead time is 20–30 working days. We offer express service (3–5 days) for emergency orders — just contact our sales team.
Absolutely. Our engineering team has 15+ years of OEM/ODM experience. We can modify flange drillings, disc profiles, seat materials, coatings, and actuator interfaces to match your existing infrastructure. Just provide your drawing or specification, and we'll deliver a prototype within 3 weeks.
We accept T/T (wire transfer), L/C (at sight), and for long-term partnerships, 30% deposit + 70% against BL copy. For first-time buyers, we recommend T/T with 30% deposit and 70% before shipment. We also offer irrevocable L/C for larger orders. Minimum order quantity is 1 piece for standard sizes.
We ship via FOB Tianjin, CIF to major US ports (Long Beach, Houston, Newark), or DDP (door-to-door) for small orders. Our logistics team handles all export documentation, and we work with experienced freight forwarders who ensure smooth customs clearance. Shipping to US West Coast takes 18–22 days by sea, 5–7 days by air.
Yes, we offer free samples for qualified buyers (you pay shipping). Sample lead time is 5–7 working days. If you are a procurement manager or engineer evaluating our valve for a project, apply for a free sample here.
Every valve comes with a 12-month warranty against manufacturing defects. Our technical support team (English-speaking) is available via WhatsApp, email, or video call for installation guidance and troubleshooting. We also provide spare parts kits (seat, seals, disc) for long-term maintenance.
“We've been using Thriveon's throttle butterfly valves on our cooling towers for 2 years. Zero maintenance so far. The linearity at 30–60% opening is impressive — our temperature control is now within ±0.5°C.”
“Finally a Chinese supplier that delivers on quality and documentation. We ordered 35 pieces for a desalination project in Saudi Arabia. The valves arrived 3 days early, and all the paperwork was perfect.”
“We needed a custom throttling valve for a chemical dosing skid. Thriveon modified the disc profile and shipped within 2 weeks. The valve works exactly as simulated. Will order again.”
“I compared quotes from 5 suppliers. Thriveon offered the best price for a metal-seated throttle valve, but what convinced me was their detailed technical proposal and fast response time. Highly recommend.”
“We use Thriveon's throttle butterfly valve with electric actuator for our wastewater flow control. Over 500,000 cycles and still going strong. No cavitation, no leakage. Great value.”
