Product catalog summary
Introduction
This document provides comprehensive technical specifications and guidelines for the use of balancing valves, specifically pressure independent control valves, in heating and cooling systems. It covers models such as RC2106, RC4240, and RC7240N, detailing their applications, functionalities, and installation procedures.
Specifications
The Tecofi balancing valves are designed for precise regulation in heating, sanitary, and cooling circuits. The RC2106 model features an oblique seat for enhanced adjustment precision and reduced resistance, resulting in minimal head losses and higher flow rates. The valves have a maximum working pressure of 20 bar and a temperature range from -10°C to +90°C, with test pressures of 30 bar for the body and 22 bar for the seat.
Applications and Benefits
Balancing valves ensure correct flow distribution in hydraulic networks, enhancing comfort, energy savings, and control. Properly balanced systems can lead to energy savings of 10-20% or more by preventing overheating or underheating in different building areas.
Installation and Adjustment
Instructions are provided for installing balancing valves on supply and return lines, with a recommended flow direction indicated on the valve body. The RC2106 model includes a digital wheel for precise adjustment and test points for measuring head losses and flow rates. The valve requires four complete turns to move from closed to fully open, with a factory preset at position 4.0.
Regulatory Compliance
The balancing process complies with the RT2000 Thermal Regulation, which mandates energy-saving measures in thermal installations. The valves meet standards such as EN 12266-1, DIN 3230, BS 5154, and ISO 5208.
Components
The valve is composed of materials like brass, ABS, PTFE, and EPDM, with detailed descriptions of each component's material and function.
DN Selection Guide
Instructions for selecting the nominal diameter (DN) based on required flow are provided, using diagrams and calculation formulas for Kv and Z coefficients. The guide explains how to calculate head losses and the importance of the Zeta ratio.
Technical Data and Charts
Detailed charts for pressure loss and Kv values for different DN sizes are included, providing essential data for system design and valve selection.
Balancing Valve RC4240
This section includes detailed balancing charts for various DN sizes, illustrating the Kv values at different positions to determine the pressure drop across the valve for specific flow rates.
Measurement Devices
The RCC balancing measurer is introduced as a tool for controlling flow rates and balancing heating and cooling systems, recording pressure and flow data viewable on its display.
Automatic Regulation Valves
Pressure-independent control valves (PICV) are described, designed for HVAC systems to maintain a constant flow rate despite differential pressure variations. They can be manually or automatically controlled, with options for on/off or proportional control using a thermo-electric actuator.
Specifications of PICV
The PICV is designed for HVAC installations, maintaining a constant flow rate regardless of differential pressure variations. It features a proportional actuator controlled by a regulator, with control signals of 0(2) - 10V or 0(4) - 20mA and an operating voltage of 24 VAC 50/60Hz. The valves have a caliber range of DN50-DN250, a flow rate range of 13-240m3/h, and are made from ductile iron QT450-10 with stainless steel stems and PTFE sealing rings.

Pourquoi équilibrer une installation ? Avantages de l’équilibrage d’une installation de chauffage et climatisation. Advantages of the heating and cooling system balancing. L’équilibrage hydraulique permet d’apporter les débits requis et donc de fournir en tout point de l’installation les quantités de chaleur désirées. Dans un même immeuble, par exemple, un certain nombre de locaux atteignent difficilement, voire parfois jamais, les températures prescrites, alors que d’autres locaux sont «surchauffés». Ce problème résulte généralement d’une mauvaise répartition des débits qui ne permet pas aux...

Exemple d’une installation simplifiée de chauffage mal équilibrée Example of a simplified heating installation badly balanced L’installation comporte trois colonnes montantes identiques, sans aucun robinet d’équilibrage. Le débit en sortie de chaudière, est calculé pour que chaque colonne reçoive un débit identique. The installation is made up of 3 identical rising columns, without any tap of balancing. La colonne 1, plus proche de la chaudière donc avec une résistance plus faible, reçoit un débit supérieur à son besoin, elle est donc sur-alimenteé. The first column, close to the boiler thus...
