The ACTIVAL VY51XXL electric two‑way valve manual provides specifications, control options, and installation accessories for PN16‑rated water and steam…
The ACTIVAL VY51XXL series is a flange‑connected electric two‑way valve with an integrated actuator. It is designed for cold/hot water control and meets a PN16 pressure rating. The actuator operates on 24 V AC low‑voltage reversible synchronous motor and supports five different control signal types.
The document lists accessory options such as sealing joints, auxiliary switches, and potentiometers, and provides a detailed selection table with valve sizes, Cv values, and electrical limits. This manual is written in Chinese.
| Valve body rating | PN16 |
|---|---|
| Actuator voltage | 24 V AC low‑voltage |
| Maximum external voltage/current | DC 30 V, 3 A |
| Wire diameter (for waterproof joint) | φ7 mm to φ9 mm |
The actuator can handle a maximum external voltage of 30 V DC and a current of 3 A.
No, you may add either auxiliary switches or an auxiliary potentiometer, but not both at the same time.
