EB50D
Electric Drainage Ball Valve
Design Features
The electric steam trap ball valve features a floating ball mechanism and steam-specific valve seat design, enabling rapid 90° on/off actuation via an electric actuator. The valve body undergoes anti-cavitation hardened treatment with streamlined drainage port flow paths to ensure high-flow condensate discharge, while integrating thermal compensation sealing to compensate for temperature fluctuations. It is equipped with 4-20mA signal control and Modbus communication capabilities for intelligent operation.
