Product Description
Shanghai Hongba Q941F46-16 DN65 Electric Fluorine-lined Ball Valve features PTFE-lined anti-corrosion design, suitable for controlling corrosive medium requirements, with long-lasting sealing and self-cleaning properties.
Core Features
Spherical Eccentric Seal Technology: Maintains a non-contact state of the sealing surface during the opening and closing process, achieves zero leakage through eccentric self-locking at the moment of closure, and reduces component wear.
Dynamic Scale Removal Design: The valve core movement path has been optimized, allowing for the removal of over 90% of crystalline or sediment deposits from the valve seat surface.
Full fluorine-lined structure: Valve body and channel covered with a 2.8mm thick PTFE layer, resistant to corrosion by strong acid and alkali media
Suitable for electric actuators: Supports on/off and adjustment control, maintenance cycle extended to twice that of conventional valves.
Application Conditions Compatibility
Suitable for pipeline systems with medium crystallization risks in industries such as chlor-alkali and metallurgy, operating pressure ≤ 1.6 MPa, temperature range -30℃ to 150℃.
Product Features
This valve body features a special anti-corrosion structural design, combined with multiple process innovations, providing a reliable fluid control solution for industrial processes.
Corrosion-Resistant Protective Structure
The main channel and ball core components are made using an integral plastic coating process, covered with a 2.5-3mm thick layer of fluoroplastic (F46/F4 options available), which has been laboratory-tested to withstand concentrations of ≤98% sulfuric acid, ≤36% hydrochloric acid, and strong alkaline mediums stably. The continuous working life exceeds 8000 hours.
Dynamic Sealing Solutions
Equipped with an elastic compensation sealing system, optimized contact pressure distribution through 3D simulation, actual leakage rate < 3×10^-6 mbar·l/s, meets ISO 15848 AH grade standard, suitable for operating conditions from -40℃ to 180℃.
Compact structural design
The flow channel has been optimized through fluid dynamics, resulting in a 42% increase in the Cv value over conventional valves and a 32% reduction in body weight. The modular design supports online maintenance, with standard maintenance operation time ≤2 hours.
Control Expansion Interface
Supports industrial-grade positioning device installation, accepts 0-10V/4-20mA control signals, stroke repeatability ±0.8%F.S. Available with multiple torque models (50Nm-2500Nm), compatible with DN10-DN400 valve bodies.
Certification Parameters
Meets GB/T 4213-2008 national standards, passes the API 607 fire resistance test, pressure-temperature ratings cover Class 150-600, suitable for corrosive medium control in the petrochemical, metallurgical, and other fields.
