Electric plastic butterfly valves combine a plastic wafer butterfly valve with a quarter-turn electric actuator for automated isolation and general disc-positioning duties in corrosive fluid systems.
The valve body and disc can be manufactured from UPVC, CPVC, PPH, or PVDF to suit different chemical compatibility requirements. Compared with metal butterfly valves, plastic construction helps avoid corrosion caused by many acids, alkalis, salts, and other compatible chemical solutions. Material selection should be based on the process medium, concentration, temperature, and operating conditions.
The wafer-type body is installed between mating pipe flanges, providing a lightweight and compact solution for chemical piping, treatment equipment, and skid-mounted systems. Its reduced weight can simplify handling and installation, particularly in non-metallic piping systems or applications where corrosion resistance is a primary requirement.
EPDM and PTFE sealing options are available for different process conditions. The valve can be equipped with ON/OFF, modulating, or intelligent electric actuators for remote open-close operation, adjustable disc positioning, and local operating-status indication.
Electric plastic butterfly valves are commonly used in chemical dosing systems, water and wastewater treatment, electroplating lines, fume-scrubbing systems, chemical storage and transfer installations, and other corrosive fluid applications requiring electrically actuated valve control.
