Founded on a rich legacy originating from Flotte Thermal Engineering in 1995, Flotte Energy Saving Company was formally established in 2013 with a robust registered capital of 101 million yuan. With three decades of deeply accumulated technical expertise, Flotte has pioneered industry-leading innovations across water equipment, HVAC systems, industrial control systems, and complex water treatment setups.
We believe that precise fluid control is the key to energy efficiency. Butterfly valves, as standard shut-off and throttling components, represent an essential part of these mechanical assemblies. To support design engineers, purchasing managers, and HVAC installers worldwide, we offer comprehensive technical butterfly valve PDF specifications, detailing torque data, flow coefficients (Cv/Kv), dimensional profiles, and chemical compatibility parameters to ensure flawless on-site integration.
Decades of manufacturing capability backed by verified facility credentials, certified production capacity, and a global logistics footprint.
How downloading and evaluating our detailed technical catalogs ensures precise system matching, prevents cavitation, and optimizes fluid dynamics.
Concentric designs feature resilient EPDM/PTFE liners ideal for low-pressure municipal systems. Triple-offset butterfly valves employ metal-to-metal seating designed to handle severe service environments up to Class 600 pressure profiles, preventing wear during rapid cycle operations.
Uncontrolled throttling in butterfly valves often results in downstream cavitation. Our engineering PDF documents contain fluid dynamic charts detailing exact hydrodynamic limits and recommended disc opening degrees (typically between 30° and 70°) to sustain laminar flow.
Proper torque calculations are critical for reliable actuation. Flotte's datasheets provide wet, dry, and dynamic torque indexes for pneumatic, double-acting, spring-return, and intelligent electric actuators to prevent premature stem failure.
Purchasing valves without referencing structured PDF dimension sheets leads to over 34% of retrofitting failures in district heating projects. Always cross-check face-to-face dimensions according to API 609 or EN 558-1 prior to welding flanges.

| Double Eccentric Valve | Carbon Steel, WCB, SS304 | PN16 / PN25 / Class 150/300 | PTFE, RTFE, Polyurethane | Chemical processes, clean steam, pharmaceutical lines |
| Triple Offset Valve (TOV) | A216 WCB, A351 CF8M | Up to PN100 / Class 600 | Stellite Hard Face + Laminated Metal | High-temp thermal oil, steam systems, petrochemical |
Why global engineers rely on Flotte's integrated heating and fluid control systems.
Specializing in plate heat exchangers, it features patented corrugated plate design, achieving 2-3 times higher heat exchange efficiency than conventional equipment.
The products cover 8 core areas such as air conditioning, heating and ventilation, and central heating. Our solutions have been verified by projects in many places around the world, and can accurately match different regional conditions and compliance requirements.
The whole process quality control system runs through the production, the products have obtained a variety of certifications, and the preferred stainless steel, titanium and other high-end materials ensure stable and durable in harsh environments.
We provide customized design, after-sales maintenance and one-stop service, multilingual team + efficient supply chain, to ensure that global customers can get timely technical and logistical support.
In centralized district heating networks, municipal water distribution, and heavy chemical setups, butterfly valves function as critical flow control devices. To guarantee seamless project delivery across Europe, the Americas, and Southeast Asia, our butterfly valves are fully certified according to major international standards:
We work closely with local design engineering firms by exporting precise CAD models and detailed PDF catalogs containing installation space tolerances, dynamic flow resistance coefficients, and specific actuator matching indexes.
From raw metal forming to high-pressure seal testing, our manufacturing line operates with precision machinery and certified processes.
Operating under strict ISO 9001, ISO 14001, and ISO 45001 standards to maintain global reliability.
As a leading Chinese supplier, our core mission is delivering stability in global hardware procurement. The manufacturing process of high-performance butterfly valves relies heavily on supply chain synchronization—from casting foundries to precision CNC seal machining. We optimize sourcing parameters to insulate international projects from raw material price shocks and shipping delays.
We manage every critical manufacturing segment under one roof: design CAD layout, sand casting inspection, mechanical processing, seat vulcanization, and pneumatic pressure validation. This minimizes dependency on sub-vendors and assures quality consistency.
We source certified stainless steels (SS304/SS316/SS316L), Duplex steels, and Hastelloy materials directly from premium domestic mills. This allows us to craft corrosion-resistant valves customized for demanding industrial fluids.
Our technological roadmap focuses on integrating IoT diagnostic modules. Next-generation smart butterfly valves will feature integrated digital positioners and vibration sensors, enabling predictive maintenance schedules and reduced system downtime.
