Marine electric butterfly valve
Brand：Pneumatic eccentric butterfly valve 型号：YD971X-16T
船用电动蝶阀Based on comprehensive information, combined with technical parameters, application scenarios, and market product comparisons:
1. Technical characteristics and standards
Core structure: Adopting a double eccentric design, the sealing performance is enhanced with increasing pressure. The butterfly frame structure reduces flow resistance and supports installation in any direction.
Drive mode: Electric actuator (such as IP67 waterproof rating), torque range 4N · M~10560N · M, supports remote PLC control.
Material and Certification:
The valve body can be made of aluminum bronze (resistant to seawater corrosion), stainless steel or cast steel, and the sealing material is EPDM/NBR/PTFE.
Compliant with the GB/T 5744-2023 marine valve standard and certified by international classification societies such as CCS and DNV.
2. Product comparison (price and parameters)
Model/Brand Price (Yuan) Diameter (DN) Material Drive Torque
Customized aluminum alloy high torque electric actuator 17010
Electric actuator 2167 2000NM stainless steel 2000N · M
Aluminum bronze butterfly valve for seawater 1146-1698 DN50~300 aluminum bronze/stainless steel medium torque
3. Application scenarios
Ship system: fuel/oil pipeline control, seawater circulation system (requiring corrosion-resistant materials).
Industrial field: chemical fluid regulation, high-temperature steam pipelines (requiring metal hard seals).
4. Selection suggestions
Small vessels: Choose a pair of clamp type aluminum bronze butterfly valves with high cost-effectiveness.
High pressure scenario: Priority cast steel valve body+electric actuator combination (one standard 1710 yuan model).
