In commercial HVAC systems, a substandard mixing or diverting valve creates a cascade of problems:
The reality: Every day your facility runs on an unreliable valve, you're losing money on energy, maintenance labor, and tenant comfort.
At Ningjin Thriveon Valve Co., Ltd., we've spent over a decade refining our HVAC three way valves to solve exactly these problems. Here's what sets our valves apart:
Class IV shut-off per FCI 70-2. Zero bypass leakage even at 200 psi differential, saving you 22-30% on chiller energy consumption.
Anti-blowout design with double O-ring sealing. Rated for 1 million cycles – 3x longer than standard brass-stem valves.
-20°F to +450°F continuous operation. EPDM or PTFE seats available for steam, hot water, or chilled water applications.
Full-face Class 125/150 flanges. Direct replacement for Jenkins, Nibco, Watts – no adapter plates needed.
Eliminate 3-4 layers of distribution markup. Your cost drops 35-50% vs. US-brand equivalents.
Air freight from Northern China to Chicago in 7-14 days. Customs-cleared with all documentation included.

"We replaced 48 Nibco T-34 three way valves with Thriveon units across a 300,000 sq ft campus. First-year energy savings hit 23%. Valve cost was 42% less than the Nibco quote. Installation was a direct swap – no modifications needed. We've standardized on Thriveon for all future HVAC projects."
"As a mechanical contractor working on federal projects, I need UL-listed, code-compliant valves. Thriveon's team provided full documentation – pressure test reports, material certs, and ASME compliance letters. Their support is faster than any US manufacturer I've worked with. Quote to delivery in 18 days."
"We've been sourcing butterfly and globe valves from Thriveon for three years. When our HVAC engineer specified three way valves for a new data center build, we didn't hesitate. The quality is consistent – every batch matches the sample. Their factory audit reports and ISO 9001 certification gave us confidence to approve this supplier."
A mixing valve has two inlets (A and B) and one outlet (AB). It blends hot and cold water to a set temperature. A diverting valve has one inlet (AB) and two outlets (A and B), routing flow to either the heating or cooling loop. Our valves are designed for dual-function use – install in any orientation with the correct actuator mounting.
Yes – our flanges match ANSI Class 125/150 dimensions exactly. Face-to-face lengths conform to MSS SP-67. For most common sizes (2"-8"), no pipe modifications are required. We recommend sending your existing valve's drawing or part number, and our engineering team will confirm compatibility within 24 hours.
Our standard MOQ is 25 units per size. However, for first-time buyers, we offer a trial order of 5 units at the same unit price. We also maintain a small stock of popular sizes (3", 4", 6") in our Los Angeles warehouse for same-week shipment.
We ship FOB Tianjin or CIF to any US port (Los Angeles, Seattle, Houston, New York). All shipments include commercial invoice, packing list, certificate of origin, and fumigation certificate. For air freight, we use DHL/FedEx priority – door-to-door in 5-7 business days. We have handled over 200 shipments to the US with 99.5% on-time delivery rate.
Absolutely. We provide OEM services including: custom body casting with your brand, specific seat materials (PTFE, EPDM, Viton), custom paint/RAL colors, and special packaging. MOQ for OEM is 100 units per size. Our engineering team will sign an NDA and provide a complete drawing within 10 business days.
All HVAC three way valves carry a 5-year warranty against manufacturing defects. This covers the valve body, disc, seat, and stem. Actuators (if purchased) carry a 2-year warranty. We replace defective units free of charge, with expedited shipping. Our quality department performs 100% pressure testing before every shipment.
Yes. We offer one free sample per company for evaluation. You pay only the shipping cost (typically $50-120 for DHL air freight). The sample valve is production-grade, not a prototype. We also provide a full refund guarantee on your first order of 5 units if the valves don't meet your performance expectations.
Take advantage of our limited-time promotion: Free sample valve + 5% discount on first order over $5,000. Valid for new customers only through March 2026.

"We manage 14 HVAC retrofit projects annually. Thriveon's three way valves cut our material costs by 38% without compromising quality. The ISO 5211 mounting pattern fits our Belimo actuators perfectly."
– James O'Brien, Mechanical Engineer, Delta Controls Inc.
"First-time international valve buyer. I was nervous, but their sales engineer walked me through the specification sheet line by line. The valves arrived with full inspection reports. I've already reordered twice."
– Sarah Chen, Facility Manager, Irvine Company Office Properties
"We installed 36 three way valves in a district energy plant. After 8 months of operation, zero failures. The Class IV shut-off reduced our bypass leakage from 12% to under 2%. The ROI on this switch was under 6 months."
– Tomás Rivera, Plant Superintendent, Enwave Energy Corporation
"As a contractor specializing in chiller plant optimization, I've specified Thriveon valves on six projects now. The lead time is consistently under 3 weeks — something no domestic manufacturer can match. Highly recommend for performance and value."
– Marcus Greene, PE, LEED AP, Mechanical Design Solutions
