The DN32 four-way mixing valve with servo drive is a device used in heating systems to regulate the temperature of the coolant. It controls the mixing of hot and return water from the boiler, ensuring the optimal supply temperature to the heating system. Thanks to four ports, the valve is able to effectively distribute liquid flows, mixing them in a given proportion.

The servo drive automatically adjusts the valve position depending on the controller signals, which allows maintaining a stable temperature in the system, responding to changes in external conditions and requests from thermostats. This improves the efficiency of the heating system, reduces equipment wear and saves energy resources.

Characteristics:

Connection to drive:

• Disassemble the valve handle, screw the anti-rotation element onto the valve cover and install the valve adapter onto the rotor shaft.
• Assemble the actuator, actuator handle, actuator position indicator onto the valve using screws: turn the adapter indicator to a position between 4 and 6 (at an angle of 45°) and make sure that the actuator handle is in the specified position – at an angle of 45°.

The Victaulic 90° elbow kit for hydraulic piping is designed to provide the most convenient connection for your boiler room. These accessories will help you complete the installation in the shortest possible time.

The proposed 90° elbow kit for hydraulic piping contains two 90° elbows, specially designed for use with a quick-connect kit with a 4-way mixer. Thanks to these elbows, you can easily change the direction of the outlets perpendicular to the boiler, ensuring the optimal connection of your system. The kit is ideal for those who need flexibility in installing heating equipment, allowing you to adapt the system to specific installation conditions. High quality materials guarantee reliability and durability in use.

What are they used for?

The pump group for quick connection kits is a ready-made solution for integrating pumps into a heating or water supply system. It includes all the necessary components for simplified installation, such as a circulation pump, shut-off valves, a check valve and thermometers. The pump group ensures efficient operation of the system by regulating the flow of the coolant and allows for easy connection to boilers or other elements of the hydraulic piping.
The proposed pump group for quick connection kits significantly simplifies the installation of the heating circuit, allowing you to connect a circuit with forced circulation for a pool, radiators or hot water supply. The group is not adjustable, but the pump speed is controlled by the system boiler.

Pump group for quick connection kits as a key element of the heating circuit

Pump groups are a key element of modern heating and water supply systems, ensuring optimal circulation of the coolant between the heat source and heating devices. They significantly simplify installation and operation, since they combine several functions in one unit: temperature control, pressure regulation and flow direction. Many pump groups are equipped with additional modules, such as bypasses, built-in safety valves and thermostats. This reduces the number of necessary connections, reduces the risk of leaks and increases the reliability of the entire system.

The FOCUS pneumatic cleaning system controller is a specialized device for automatic control of the heat exchanger and burner cleaning system from ash and other solid deposits, designed for installation on solid fuel boilers. It controls the supply of compressed air to the pneumatic cleaning system, ensuring regular removal of deposits from surfaces, which helps maintain high efficiency of the equipment. The proposed pneumatic cleaning system controller can operate in stand-alone mode or integrate with the boiler control system, ensuring synchronization of cleaning processes with its operation.

Why is it important to clean your boiler, and is it better to clean it automatically?

During the operation of the boilers, heat exchangers gradually accumulate ash deposits, which causes resistance to air flow and reduces the efficiency of heat exchange. This leads to a decrease in power and a decrease in efficiency. Manual cleaning requires a complete shutdown of the boiler, which is inconvenient for consumers and personnel. The controller for pneumatic cleaning systems is designed to control the cleaning of the boiler by pneumatic means.

The pneumatic cleaning system solves this problem automatically, without the need to stop the boiler. It uses compressed air to remove deposits inside the heat exchanger, significantly increasing the efficiency of the equipment. The device is mounted in the front of the heat exchanger and periodically blows high-pressure air through the internal components of the boiler, which helps remove accumulated ash.

The FOCUS pneumatic cleaning system controller controls the activation intervals of the pneumatic valves responsible for supplying air for cleaning. It allows you to adjust the frequency of operation, adapting the cleaning process to specific operating conditions.

During operation, boiler heat exchangers accumulate ash, which reduces their efficiency due to increased aerodynamic resistance. This leads to a decrease in efficiency and a decrease in boiler power. Manual cleaning requires a complete shutdown of the equipment, which is inconvenient for both consumers and service personnel.

The FOCUS Air Cleaning System automates this process, allowing the heat exchanger to be cleaned without having to shut down the boiler. It uses compressed air to remove ash deposits that build up inside the heat exchanger, helping to maintain optimum efficiency and increase boiler uptime. The cleaning process involves regularly blowing high-pressure air through the heat exchanger to help dislodge and remove accumulated residue.

FOCUS pneumatic cleaning system:

• ensures increased intervals between boiler cleanings;
• increasing the time of continuous heat generation;
• provides effective cleaning of deposits;
• reduces the need for manual labor for maintenance.

The pneumatic cleaning system allows to significantly increase the intervals between cleanings, reduces the need for manual work and is suitable for both FOCUS solid fuel boilers and boilers from other manufacturers.
