Introduction
This manual provides essential information for the installation, operation, and maintenance of the ESBE MBA132 DN25 3-Way Motorized Ball Valve. The MBA130 series valves are designed for efficient switching in heating and cooling systems, ensuring reliable performance and bubble-tight sealing according to EN12266-1. Please read this manual thoroughly before installation and operation to ensure safe and correct usage.
Product Overview
The image displays a typical ESBE motorized ball valve, similar to the MBA132 model. It consists of a metallic 3-way ball valve body with threaded connections (visible as G 1" in the product title, though the image shows DN 20 / 3/4"). Mounted on top is a black electrical actuator, labeled 'ESBE MBA100', which controls the valve's position. The actuator is powered by 230V AC and features a 0.85m long electrical cable for connection. The unit is designed for a 90° rotation angle, facilitating on/off or diverting functions in fluid systems. The actuator also includes an anti-condensation resistor for enhanced durability.
- Valve Type: 3-Way Ball Valve
- Actuator Type: 2-point control, On/Off function
- Power Supply: 230 V AC, 50 Hz
- Rotation Angle: 90°
- Sealing: Bubble-tight according to EN12266-1
- Features: Auxiliary switch, anti-condensation resistor
Setup and Installation
1. Unpacking and Inspection
Carefully remove the valve and actuator from its packaging. Inspect all components for any signs of damage during transit. Ensure all parts, including the valve body, actuator, and any included screw kit, are present.
2. Mounting the Valve
The MBA132 valve is designed for easy integration into piping systems. It features external G 1" threads for connection. Ensure the system is depressurized and drained before installation. Apply appropriate thread sealant to ensure a leak-free connection. The valve can be installed in any orientation, but ensure sufficient space for the actuator and future maintenance.
3. Attaching the Actuator
The actuator is designed for quick and easy attachment to the ball valve using a pin mechanism. Align the actuator with the valve stem and secure it firmly. Ensure the actuator is properly seated and locked into place to allow for correct valve operation.
4. Electrical Connection
The actuator requires a 230 V AC, 50 Hz power supply. Connect the 0.85m cable to the appropriate electrical terminals. The actuator features a 2-point control for on/off functionality and an additional auxiliary switch. Consult a qualified electrician for wiring if you are unsure. Ensure all electrical connections comply with local regulations and safety standards.
Operating Instructions
The ESBE MBA132 operates with a simple on/off function, controlled by the 2-point actuator. When power is applied, the actuator rotates the ball valve 90° to either an open or closed position, or to divert flow in a 3-way configuration. The auxiliary switch can be used to provide feedback on the valve's position or to control other components in the system.
- Power On: Applying power to the actuator will initiate a rotation to its designated position.
- Power Off: Removing power will typically cause the actuator to remain in its last position, or return to a default position if designed for spring return (check specific model details).
- Manual Override: Some actuators may have a manual override lever or knob. Refer to the actuator's specific instructions if manual operation is required.
Maintenance
The ESBE MBA132 valve and actuator are designed for long-term, maintenance-free operation under normal conditions. However, periodic checks are recommended:
- Visual Inspection: Regularly inspect the valve and actuator for any signs of leaks, corrosion, or physical damage.
- Connection Integrity: Ensure all pipe connections are secure and free from leaks. Check electrical connections for tightness and integrity.
- Actuator Function: Periodically observe the actuator's operation to ensure smooth and complete rotation.
- Anti-Condensation Resistor: The integrated anti-condensation resistor helps protect the internal electronics. No user maintenance is required for this feature.
Before performing any maintenance, ensure the system is depressurized, drained, and the power supply to the actuator is disconnected.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Actuator does not move | No power supply; Incorrect wiring; Actuator fault | Check power supply and circuit breaker. Verify wiring connections. If problem persists, contact support. |
| Valve not fully opening/closing | Obstruction in valve; Actuator not properly mounted; Actuator fault | Inspect valve for debris. Re-check actuator mounting. Contact support if mechanical issue. |
| Leakage from valve connections | Improperly sealed threads; Damaged threads/fittings | Ensure proper thread sealant was used and connections are tight. Replace damaged components if necessary. |
