UPVC Butterfly Valve With Electric Actuator
The butterfly valve with actuator utilizes a structural UPVC body to prevent material cracking. The non-metallic electrically actuated butterfly valve ensures leak-free performance and superior chemical resistance in industrial acid-base pipelines.
Stainless Steel Electric Wafer Butterfly Valve
The butterfly valve with actuator utilizes a structural UPVC body to prevent material cracking. The non-metallic electrically actuated butterfly valve ensures leak-free performance and superior chemical resistance in industrial acid-base pipelines.
Electric Flanged Soft Seat Butterfly Valve
These electric-actuated butterfly valves feature a standard double-flanged body design. The heavy-duty actuated butterfly valve integrates a resilient soft seat to ensure zero-leakage, gas-tight sealing under standard pressure in municipal and industrial utility lines.
Fluorine Lined Wafer Motorized Butterfly Valve PTFE FEP PFA
The electric butterfly valve features a fluoroplastic liner using PTFE, FEP, or PFA. The corrosion-resistant electric actuator butterfly valve ensures zero leakage for aggressive chemicals in chemical, food, and pharmaceutical systems.
Food Grade Tri-Clamp Electric Operated Butterfly valve
The butterfly valve with actuator utilizes sanitary tri-clamp connections for rapid disassembly and washdowns. The polished electric-actuated butterfly valves fully comply with hygiene standards in food, beverage, and pharmaceutical manufacturing.
Electric Butterfly Valve By Hard Seal
Why Choose Hearken Electric Actuated Butterfly Valves?
Low-Torque Configuration With Zero-Leakage Isolation
Hearken offers dual-seat configurations for different working conditions. Our soft seals utilize rubber or PTFE to fill sealing gaps through material deformation. Our hard seals feature advanced metal surfacing to withstand high temperatures and high pressures. Both configurations use a bi-directional self-tightening design to ensure zero leakage.
This triple eccentric structure utilizes multi-eccentric layouts of the stem, disc, and body. This unique geometry allows the disc to generate a self-tightening force via line contact upon closing. This low-torque design eliminates seat friction throughout the rotational stroke, allowing a compact and cost-effective actuator pairing.
The integrated electric actuators precisely control this drive system to ensure tight disc-to-seat shutoff. This automated setup supports both analog and on-off control modes. Built-in overload protection effectively prevents seal damage during abnormal working conditions.

FAQ
No. Our design uses the standard ISO 5211 platform to mount the actuator directly onto the valve flange. This integrated connection eliminates brackets and couplings, preventing alignment shift or switch drift during transit.
Every electric actuator contains a thermal overload protector inside the motor windings. If a valve stalls or a blockage occurs, the sensor cuts power automatically to prevent seat damage and motor burnout.
We size our motorized packages with a 30% to 50% safety torque margin over the valve’s peak breakaway torque. This extra power allows the motor to overcome initial rubber friction easily under full working pressure.
Yes, severe pipeline misalignment creates high bending stress that can strip the actuator gears over time. To handle minor, unavoidable pipeline tolerances, our precision machining aligns the actuator centered onto the heavy-duty ISO 5211 pad to stabilize the shaft and prevent uneven wear.
Our standard IP67 weatherproof enclosures handle outdoor rain, and you can add internal heaters to prevent condensation. For fully submerged or flooded applications, we recommend our HEA(D) series IP68 submersible actuators.
We pack bulk orders in reinforced wooden crates with custom cradles. These cradles secure the heavy valve body tightly to isolate the top-heavy actuator from shift and impact.
No, standard on/off configurations cannot be modified into modulating control after delivery. To cover different requirements, we offer three factory options: dedicated on/off types, dedicated modulating types, and multi-functional models that support both modes.
No. The valve utilizes vulcanized-to-body or rigid-backed cartridge liners that mechanically lock inside the valve cavity. This rigid backing prevents the rubber from migrating or tearing when the disc rotates open after storage.
