Balancing valve - 1/2"; Kv 1,75 IVAR.CIM 787

Product detailed description

This balancing valve is commonly used in residential and commercial heating and cooling systems to ensure even distribution of thermal energy. Installers and service technicians use it to regulate flow rates and maintain differential pressure in closed-loop systems. It is suitable for applications such as underfloor heating, fan coil units, and radiant panels, where precise control is essential for system efficiency.

During installation, the valve is integrated into the circuit to allow flow adjustment without the need to drain the system. It is particularly useful in multi-zone systems where individual circuits require specific flow settings. Its compact design and durable construction make it ideal for tight spaces and long-term operation in fluctuating conditions.

Technical parameters

Installation and connection

Installers should ensure the valve is positioned in a straight section of pipe with sufficient clearance for access. The 1/2 inch connection requires standard thread preparation and sealing methods such as PTFE tape or thread sealant. Before tightening, check the alignment of the valve body to avoid stress on the pipe joints. Common installation errors include incorrect orientation and over-tightening, which can damage the internal components. Always verify the direction of flow indicated on the valve body to prevent improper operation.

Compatibility and accessories

This valve is compatible with standard heating and cooling systems using water as the heat transfer medium. It can be paired with differential pressure controllers and flow meters for enhanced system control. For accurate flow setting, a manometer or pressure gauge may be required. Additional components such as union fittings or isolation valves might be needed depending on the system configuration.

Technical background for designers

The valve operates by adjusting the cross-sectional area through which fluid flows, allowing precise control of flow rate and pressure drop. The CW602N-M brass alloy offers good mechanical strength and thermal conductivity, ensuring reliable performance over time. Integration into the system requires consideration of the overall hydraulic balance and the impact of the valve’s flow characteristics on pump performance. Long-term efficiency depends on proper sizing, correct installation, and regular inspection for signs of wear or blockage.

Service and operation

Periodic inspection is recommended to ensure the valve continues to operate within specified parameters. Check for signs of leakage, corrosion, or blockage, especially in systems with high mineral content. The presence of fixed end members allows for measurement without draining the system, facilitating routine checks. No scheduled service intervals are specified in the provided data; however, any abnormal operation should be investigated promptly.

Frequently asked questions

Can this valve be used in a closed-loop cooling system?
Yes, it can be used in closed-loop cooling systems provided the operating temperature does not exceed +120°C and the fluid is compatible with brass materials.

Is it possible to measure flow without removing the valve from the system?
Yes, the valve includes fixed end members that allow flow measurement without the need to remove or drain the valve.

What type of sealing method is recommended for the 1/2 inch connection?
A standard sealing method such as PTFE tape or thread sealant is suitable for the 1/2 inch threaded connection.

Can this valve be used with glycol-based fluids?
It is suitable for glycol-based fluids as long as the concentration and temperature remain within the operating limits of the material and system.
