MIX PLUS RANGE mixing valve

Product catalog summary

Overview
The document provides a comprehensive overview of the Diamix PLUS and Compamix PLUS motorised valves by Comparato Nello SRL. These valves are designed for mixing hot and cold fluids, temperature regulation in thermal exchange systems, and are suitable for high/medium temperature heating systems with weather compensation. They are applicable in both civil and industrial settings and compatible with Building Management Systems (BMS).

Functions
The valves offer fixed-point temperature control, weather compensation with external probe reading, remote temperature setpoint adjustment via a 0-10V signal, and remote control using the Modbus-RTU protocol. The MixTool software facilitates communication between a PC and the mixing valve.

Specifications
The valves operate on 230V or 24V 50Hz power supply, with a maximum power consumption of 15-20 VA. They have an IP65 protection degree and can operate in temperatures ranging from -10°C to 50°C. The fluid temperature range is -10°C to 100°C, extendable to -20°C to 120°C with a spacer. The valves use a contact-type NTC 10kΩ temperature probe and have a precision of ±1°C.

Operation
The valves offer three types of operation: fixed-point regulation, weather compensation for heating systems, and analogical setpoint setting. The fixed-point regulation maintains a constant outlet temperature, while the weather compensation function adjusts the outlet temperature based on external temperature readings. The analogical setpoint setting allows temperature adjustments via a 0-10V input.

Remote Management
The valves are equipped with a MODBUS RTU interface, allowing for remote management and integration with BMS. The MixTool software provides a user-friendly interface for managing the valve's functions.

Electrical Connections
Electrical connections should be made inside a proper branch box. The system includes digital inputs for pump control and forcing towards hot or cold, as well as an analog input for temperature setpoint adjustment.

Versions and Installation
The Diamix PLUS is available in diameters ranging from 1/2" to 1", while the Compamix PLUS is available in larger diameters. Proper installation requires ensuring constant and similar pressure values at the valve inlets. The actuator should not be installed facing downwards.

Application Examples
The document provides examples of applications such as weather compensation for high-temperature systems and plate heat exchanger temperature regulation.

Additional Specifications
The valves feature electronic fixed-point, weather compensation, or 0-10V signal temperature regulation. They are equipped with an electronic PID regulator, remote control via Modbus-RTU protocol, and have an adjustment range of -15°C to +90°C with an accuracy of ±1°C. The operating time is 35 seconds per 90° rotation, and they function within an operational room temperature of -10°C to +50°C. The valves are made from brass CW617N and have a degree of protection rated at IP65.

Dimensions and Connections
The document provides detailed dimensions for various models, including DN sizes and corresponding measurements. The valves are compatible with ISO 5211 connections and are available with different union sizes.

Accessories
Accessories include insulation spacers and manual overrides, which can be added by appending "D1" or "D2" to the product code. Additional accessories include a brass immersion probe with connector (code "K"), RS485-USB interface (code USBMOD), and an external temperature probe (code RFSONDAE).

Standards and Certifications
The company, Comparato Nello S.r.l., is UNI EN ISO 9001:2015 certified, ensuring quality management standards are met.

Diamix PLUS - Compamix PLUS MIXING / TERMOREGULATING MOTORISED VALVES WITH ELECTRONIC FIXED-POINT, WEATHER COMPENSATION OR 0-10V SIGNAL TEMPERATURE REGULATION OPERATION Diamix PLUS and Compamix PLUS thermoregulating/mixing motorised valves operate thanks to a built-in electronics which allows an easy and user-friendly programming, directly from the actuator. Using the appropriate probe, the regulator detects the temperature of the water at the valve outlet and modifies the position of the sphere inside the 3-way ball valve by suitably mixing the hot inlet with the cold inlet. The outlet temperature...
