Description
ESBE MBA132 3‑Way Diverter Valve 1.25″ BSP Male 11.3 Kvs (43102600)
The ESBE MBA132 is a tough, reliable 3‑way motorised ball valve built for proper flow control in heating and cooling systems. If you want a valve that’s accurate, air‑bubble tight, and built to last, this is the one installers trust. Fully compliant with EN12266‑1, it delivers dependable shut‑off and smooth operation in demanding systems.
The actuator runs on 230V AC (50 Hz) using a simple 2‑point on/off signal — ideal for straightforward control without overcomplication. It comes pre‑wired with 0.85m of cable, includes a 6A auxiliary switch, and features an anti‑condensation resistor to protect the electronics. The valve rotates 90° with a full operating time of 40 seconds. A solid metallic spigot locks the actuator to the valve body, making installation and removal quick and secure. Available in DN20–25 sizes.
The MBA132 uses a G‑Type flat‑faced connection and must be paired with flat‑faced union connectors and washers. For a clean, leak‑free install, we recommend using three of the following adaptors:
1.25″ Flat Faced Union Adaptor x 28mm Press Fit
Features:
- Air‑bubble tight shut‑off for reliable system control
- Built‑in auxiliary switch for flexible wiring options
- Anti‑condensation resistor protects internal electronics
- Fast, simple installation with secure actuator mounting
