Check valve EURA SPRINT, 1" FF, Kv 10,40

Product detailed description

Check valves are essential components in pump and heating systems where unidirectional flow must be maintained. They are commonly used in residential and commercial buildings, including heating circuits, circulation systems, and pump stations. Installers often encounter these valves in applications where backflow could damage equipment or reduce system efficiency. The IVAR EURA SPRINT model is specifically suited for such environments, offering reliable performance in systems with moderate to high flow rates and temperatures.

Correct selection and installation of check valves are critical to system integrity. The valve must be sized to match the flow requirements and installed in a way that minimises turbulence and pressure loss. In systems with variable flow conditions, the valve must respond quickly to flow changes without causing excessive pressure drop or vibration. The EURA SPRINT model is designed for these conditions, ensuring stable operation in a range of hydraulic environments.

Technical parameters

Material	nickel-plated brass CW617N
Operating temperature	+150 °C
Nominal pressure	PN 4
Weight	0.39 kg
Code	CIM30VA025
Brand	IVAR

The operating temperature limit of +150°C allows the valve to be used in high-temperature heating systems. The nominal pressure rating of PN 4 indicates suitability for systems with moderate pressure levels. The Kv value of 10.40 is a key factor in determining the valve's capacity to handle flow rates, which is essential for proper sizing in system design.

Installation and connection

The EURA SPRINT check valve is equipped with 1 inch FF (female-female) connections, which are standard in many heating and pump systems. Installers should ensure that the mating threads are clean and free from debris before tightening. The valve should be installed in the correct orientation to allow flow in the intended direction. A common mistake is reversing the valve, which can lead to leakage or failure. It is also important to check that the system pressure does not exceed the PN 4 rating to avoid mechanical stress on the valve body.

Compatibility and accessories

The valve is compatible with standard heating and pump systems that use 1 inch FF connections. When installing, ensure that the system includes appropriate fittings and seals to maintain a tight connection. No additional accessories are required for standard installation. The valve is not listed as compatible with any specific alternative models in the product range.

Technical background for designers

The EURA SPRINT check valve operates using a flap mechanism that opens under forward flow and closes to prevent backflow. The nickel-plated brass CW617N construction provides resistance to corrosion and wear, making it suitable for long-term use in water-based systems. The material's mechanical strength supports the valve's ability to withstand operating pressures and temperatures. The valve's integration into a system depends on the flow dynamics and the need for minimal pressure loss. The Kv value is a key factor in determining the valve's impact on system performance.

Service and operation

The valve requires minimal maintenance under normal operating conditions. Regular visual inspections can help identify signs of wear or corrosion. If the valve is used in systems with particulate matter, it is advisable to check for debris accumulation that could affect the flap's movement. No specific service intervals are provided in the technical data.

Frequently asked questions

Can the EURA SPRINT check valve be used in a heating circuit with a circulation pump?
Yes, the valve is suitable for use in heating circuits with circulation pumps. It is designed to operate at temperatures up to 150°C and supports flow rates according to its Kv value.

Is the valve compatible with systems using glycol-based media?
There is no specific information on compatibility with glycol-based media. Refer to the manufacturer's technical data sheet for confirmation.

Can the valve be installed in a vertical position?
Yes, the valve can be installed in a vertical position as long as the flow direction is maintained and the system pressure does not exceed the PN 4 rating.

What is the maximum allowable operating pressure for this model?
The valve is rated for a nominal pressure of PN 4, which means it is suitable for systems operating at up to 4 bar pressure.
