FAQ
What is the advantage of electric butterfly valves over pneumatic?
Electric butterfly valves require no compressed air infrastructure, making them ideal for sites without air supply. They offer clean, quiet operation, lower energy consumption, and easy integration with control systems. Maintenance is limited to periodic inspections versus pneumatic filter maintenance.
What control signals are supported for modulating control?
KINKO electric butterfly valves support 4-20mA, 0-10V, 2-10V, and 1-5V control signals. HART and Modbus communication options are available for advanced diagnostics, calibration, and integration with DCS or building automation systems.
What is the typical response time for electric butterfly valves?
Response time depends on actuator size and torque requirements, typically ranging from 15 to 60 seconds for full stroke (90° rotation). For faster response (≤0.3 sec), pneumatic actuation is recommended. Electric is preferred for applications where speed is not critical.
Can electric butterfly valves be used in explosive atmospheres?
Yes. ATEX-certified explosion-proof electric actuators are available for Zone 1 and Zone 2 hazardous areas. These models feature explosion-proof enclosures and are suitable for petrochemical, gas, and other explosive environments.
Are electric butterfly valves suitable for high-cycle applications?
Electric butterfly valves are designed for moderate cycle frequencies. For high-cycle applications exceeding 100 cycles per hour, pneumatic actuation with 1-million-cycle durability is recommended. Electric is ideal for applications with lower cycle rates and remote monitoring requirements.
