Check valve EURA SPRINT, 1/2" FF, Kv 2,00

Product detailed description

Check valves are essential components in pump and heating systems where unidirectional flow is required. They prevent backflow and ensure system integrity in applications such as circulation pumps, condensate return lines, and domestic hot water circuits. Installers and technicians working on residential and commercial buildings often integrate these valves into systems to maintain pressure and flow stability. The IVAR EURA SPRINT model is suitable for systems with moderate flow rates and temperatures up to +150 °C, making it a reliable choice for a wide range of installations.

Proper selection and installation of check valves are crucial for system performance. The valve must be compatible with the system's pressure and temperature conditions and must be sized correctly to avoid flow restrictions or excessive pressure drop. The Kv value is a key factor in determining the valve's capacity to handle the required flow rate without causing turbulence or cavitation.

Technical parameters

Material	Nickel-plated brass CW617N
Operating temperature	+150 °C
Nominal pressure	PN 4
Weight	0.164 kg
Code	CIM30VA015
Brand	IVAR

The operating temperature limit of +150 °C allows the valve to be used in systems with heated water or glycol-based fluids. The nominal pressure rating of PN 4 ensures the valve can withstand typical pressures in low-pressure heating and pump systems. The Kv value of 2.00 is used in hydraulic calculations to determine the valve's flow capacity and to size the system components correctly.

Installation and connection

The IVAR EURA SPRINT check valve is equipped with a 1/2 inch internal thread (FF) connection on both ends. When installing, ensure the valve is oriented correctly with the flow direction marked on the body. The internal thread must be cleaned and lubricated with a suitable sealing compound before tightening. Use a wrench to secure the connection without over-tightening, which can damage the threads or the valve body. Common installation errors include incorrect orientation, which can lead to flow restriction or failure to close properly, and using incompatible sealing materials that may degrade under operating conditions.

Compatibility and accessories

The valve is compatible with standard heating and pump systems that operate within the specified pressure and temperature limits. It can be used in conjunction with circulation pumps, expansion vessels, and other system components. No additional accessories are required for standard installations, but sealing compounds and thread sealants should be selected based on the system's media and operating conditions. No related products are listed for this model.

Technical background for designers

The IVAR EURA SPRINT check valve operates on a lift disc mechanism, where the flow opens the disc and allows media to pass. When the flow reverses, the disc closes against a seat, preventing backflow. The nickel-plated brass CW617N construction provides good corrosion resistance and mechanical strength, making it suitable for use with water and glycol-based fluids. The valve's performance is influenced by the system's flow rate, pressure differential, and the viscosity of the media. Proper integration into the system ensures that the valve operates efficiently and does not cause unnecessary pressure loss or vibration.

Service and operation

The valve requires minimal maintenance under normal operating conditions. Regular inspection should include checking for leaks at the connections and ensuring the valve opens and closes freely. If the system is exposed to particulate matter or debris, the valve should be cleaned periodically to prevent clogging or wear. No specific service intervals are provided in the brief, but any signs of corrosion, leakage, or operational irregularities should be addressed promptly to avoid system failure.

Frequently asked questions

Can the IVAR EURA SPRINT be used in glycol-based systems?
Yes, the valve is suitable for use with glycol-based fluids as long as the operating temperature and pressure remain within the specified limits.

Is the valve suitable for installation in vertical pipelines?
Yes, the valve can be installed in vertical pipelines as long as the flow direction is maintained and the valve is properly supported.

What is the maximum allowable temperature for the valve?
The maximum operating temperature is +150 °C as specified in the technical data.

Can the valve be used in systems with frequent flow reversals?
Yes, the valve is designed to respond to flow direction changes and will close automatically when the flow reverses.
