ESBE MBA121 2 Way Motorised Ball Valve Internal Thread, 230V

Description

The ESBE MBA121 DN25 motorised ball valve provides dependable on/off flow control for heating and cooling systems. With a high flow DN25 body, 230V actuator and air bubble tight shut-off, it is a practical choice for homeowners upgrading a heating system and for installers requiring a reliable zone control valve.

Its compact actuator operates with a simple 2 point SPST signal, while the anti condensation resistor helps protect the internal electronics. The valve delivers a Kvs flow rate of 60 m³/h and is suitable for water based heating and cooling circuits with media temperatures from 0°C to 90°C.

Key Features

High Flow DN25 Control

A 25mm nominal bore and 60 m³/h Kvs value support efficient flow control in larger heating and cooling circuits.

Reliable 230V Actuator

The 230V AC, 50Hz actuator uses a 2 point SPST control signal for straightforward open/close operation.

Air Bubble Tight Shut Off

Engineered to EN 12266-1 leakage rate A, helping to prevent unwanted internal leakage when the valve is closed.

Anti Condensation Protection

An integrated anti condensation resistor helps reduce moisture build up around the actuator electronics.

Easy Actuator Removal

A metallic spigot connection allows the actuator to be fitted or removed quickly and securely during installation or servicing.

Suitable for Heating & Cooling

Designed for water based heating and cooling applications, with a media temperature range of 0°C to 90°C.
