This product is a 2 3B flange-connected rotary electric three-way valve, which is a combined valve and electric actuator. The actuator adopts an AC24V low-voltage reversible rotating motor. Its control methods include the proportional control with the WY7211 digital controller with the feedback potentiometer, the proportional control with the T9065 T991 proportioning action electrical controller with the impedance input and the proportional control with the WY7211 R20/21 digital controller with the 4 20mA DC input and the proportional control with the WY7217 digital controller with the 2 10V DC input. Features: 1) Rotary electric three-way valve, small and light; 2) Valve and electric actuator integrated structure; 3) Rich and diverse control input signal types; 4) Low power consumption and long life of the electric actuator; 5) Linear flow characteristics
The AI-6303C VY54 is a compact, lightweight flange‑type electric three‑way valve that integrates the valve body and actuator in one unit. It supports a variety of control signal types and is intended for use in air‑conditioning and chilled‑water systems.
This manual covers safety precautions, installation steps, wiring diagrams, technical specifications, actuator details, part identification, and routine maintenance procedures to ensure reliable operation and long service life. This manual is written in Japanese.
