Balancing valve - 1"; Kv 6,96 IVAR.CIM 747

Product detailed description

This balancing valve is commonly used in residential and commercial buildings for the precise control of fluid flow in heating and cooling circuits. Installers typically integrate it into systems where accurate flow regulation is essential for energy efficiency and system balance. The valve allows for the adjustment of differential pressure and flow rate, ensuring uniform distribution of thermal energy across the system. Its design includes fixed end elements for measurement without the need for draining the system, making it suitable for maintenance and diagnostics during operation.

Correct installation of this valve is crucial for maintaining system performance. It is often found in central heating systems, underfloor heating loops, and air conditioning units. The valve supports both manual and automated balancing procedures and is compatible with standard pipe layouts and instrumentation. Technicians must ensure that the valve is installed in the correct orientation and that all connections are secure and leak-free.

Technical parameters

Material	Brass CC752S
Operating temperature	-10 °C
Nominal pressure	PN 25
Weight	1.125 kg
Code	747100
Brand	IVAR

The valve is rated for a nominal pressure of PN 25, which means it can operate under pressures up to 25 bar. The flow coefficient, Kv 6.96, indicates the volume of water flowing through the fully open valve per hour at a pressure drop of 1 bar. These parameters are essential for determining the correct valve size and ensuring that the system maintains the required flow rates and pressure levels under varying load conditions.

Installation and connection

The valve is designed for 1 inch pipe connections and should be installed in accordance with standard piping practices. Prior to installation, verify the system pressure and temperature conditions to confirm compatibility with the valve's specifications. Ensure that the valve is positioned in a straight section of pipe with sufficient clearance for access and maintenance. Common installation errors include incorrect orientation, failure to align the flow direction, and neglecting to support the valve with proper pipe bracing. Always check the seating of the valve body and the integrity of the sealing surfaces before tightening the connections.

Compatibility and accessories

This valve is compatible with standard copper and steel piping systems and can be integrated with pressure gauges, flow meters, and control actuators for enhanced system management. When installing, ensure that all associated components, such as unions, gaskets, and mounting brackets, are correctly specified and available. No additional products are required for standard installation, but designers may consider supplementary components based on the specific application requirements.

Technical background for designers

The valve operates via a throttling mechanism that adjusts the flow passage to regulate the fluid flow rate. Constructed from brass CC752S, it offers high resistance to corrosion and mechanical wear, making it suitable for long-term use in closed-loop systems. The material's properties ensure dimensional stability over time and compatibility with common heating fluids. Proper integration into the system requires consideration of the hydraulic balance, especially when multiple circuits are involved. The valve's performance is influenced by the upstream and downstream piping configuration, as well as the presence of other flow control devices in the circuit.

Service and operation

Routine inspection is recommended to ensure the valve remains free from debris and operates smoothly. Check for signs of leakage, especially at the connection points and sealing surfaces. Verify that the flow adjustment mechanism moves freely and that the valve remains responsive to manual or automated control inputs. No specific service intervals are provided in the technical documentation; however, regular visual checks and functional testing are advised to maintain system reliability.
