Electric High Performance Butterfly Valves

Electric high-performance butterfly valve is an advanced valve combining electric actuator and optimised structural design, specially designed for high-precision flow regulation, severe working conditions and automation control needs, combined with sealing reliability, long life and high efficiency. The following is a detailed description of its core features and technical details:

1. core structure and technical characteristics
Structure design:
Top-mounted valve body: Adopting top-mounted structure reduces the number of connection bolts under high-pressure and large-diameter conditions, enhances the overall reliability and reduces the impact of self-weight on the valve's work.
Three-dimensional butterfly plate optimisation: the butterfly plate is disc-shaped and rotates around the axis (0°-90°), which reduces resistance and improves the flow efficiency through hydrodynamic design.
Intelligent actuator: Equipped with angle stroke electric actuator (0-90°swing), supporting remote control, automatic adjustment and fault self-diagnosis function.
Material selection:
Valve body and butterfly plate: carbon steel (WCB), stainless steel (304/316L) or alloy steel, pressure resistance up to Class 600 (PN100), applicable temperature range -29°C ~ +450°C46. 450°C.
Sealing surface: Cemented carbide surfacing (Stellite), PTFE soft seal or metal + graphite composite layer, adapting to high temperature, particle scouring and corrosive media.
2. Performance advantages
High precision control:
Flow regulation accuracy of ±1%, support for 20 ° - 70 ° opening range of fine-tuning, suitable for chemical industry, electric power and other need for accurate flow control scenarios.
Short response time of electric actuator (full open/close only takes a few seconds), suitable for emergency cut-off or fast switching system.
Seal reliability:
Leakage rate ≤ 10 ppm (in accordance with API 598 standard), two-way seal design can withstand reverse medium pressure.
Hard sealing type is wear-resistant, with a life span of over 100,000 openings and closings and long maintenance intervals.
Energy efficiency and adaptability:
Some models are integrated with solar power modules to reduce external energy consumption (e.g. agricultural irrigation scenarios).
Support flange, clamp and other connection methods, suitable for DN50-DN1200 pipeline.

Applications

Industrial automation system:
Petrochemical industry: high-temperature oil and gas transmission, acid medium shunt/combined flow control.
Electric power and metallurgy: boiler steam conditioning, blast furnace gas pipeline (temperature resistance ≤ 600 ° C).
Utilities:
Water treatment and municipal engineering: water supply and drainage system, fire-fighting water supply (low and medium pressure scene adapted to soft seal type).
HVAC: hot and cold water flow regulation, support -20°C~+150°C temperature range.
Special working conditions:
High-vacuum environment (vacuum ≤ 1.0×10-⁶ Pa) under the gas on and off control (need special high-vacuum models).
