Pressure reducing valve - with fitting and pressure gauge - 2 "MM IVAR.5350

Product detailed description

Pressure reducing valves are essential in systems where the supply pressure exceeds the safe operating level for downstream components. This model is suitable for residential and commercial installations, including heating systems, water supply lines and irrigation circuits. It ensures stable pressure levels, protecting equipment such as boilers, heat exchangers and domestic appliances. Installers typically use this valve in mains-fed systems where pressure fluctuations are common, such as in municipal water supply lines or district heating networks.

Correct installation and sizing are crucial for system performance. The valve must be positioned in a location that allows easy access for maintenance and inspection. It is typically installed upstream of sensitive equipment to prevent damage from high-pressure surges. The pressure gauge included provides real-time monitoring of the reduced pressure, enabling adjustments to be made as needed.

Technical parameters

Material	Brass CW602N
Operating temperature	+40 °C
Nominal pressure	PN 25
EAN	8016615077025
Weight	4.304 kg
Code	535091
Brand	IVAR

The operating temperature limit of +40°C is suitable for most heating and plumbing applications, but not for high-temperature systems such as steam or condensing boilers. The PN 25 rating indicates that the valve is suitable for systems with a maximum allowable working pressure of 25 bar. The CW602N brass construction ensures good corrosion resistance and mechanical strength, making it suitable for use with water and compatible fluids.

Installation and connection

The valve is connected using external metric threads, ensuring compatibility with standard pipe fittings in European installations. The fitting included is designed for secure and leak-free connection to the system. During installation, it is important to ensure that the flow direction is correct, as indicated on the valve body. A common mistake is incorrect orientation, which can lead to improper pressure regulation or internal damage. The pressure gauge should be mounted in a visible location for easy monitoring. After installation, the system should be tested for leaks and the pressure adjusted to the desired level using the adjustment screw.

Compatibility and accessories

This pressure reducing valve is compatible with standard plumbing and heating systems that operate within the specified pressure and temperature limits. It is typically used in conjunction with expansion vessels, safety valves and check valves to form a complete pressure management system. For complete functionality, it is recommended to install a pressure relief valve downstream to prevent overpressure in case of failure. No additional accessories are included with this model.

Technical background for designers

The valve operates by reducing the inlet pressure to a set level using a spring-loaded diaphragm and adjustment mechanism. The CW602N brass body provides good thermal conductivity and resistance to corrosion, making it suitable for long-term use in water systems. The NBR sealing material is compatible with water and common additives such as antifreeze. The valve’s performance is influenced by the inlet pressure, temperature and the condition of the diaphragm and spring. To ensure long service life, the system should be free from particulate matter and chemical contaminants that could degrade the sealing materials.

Service and operation

Regular inspection of the pressure gauge and valve body is recommended to ensure proper operation. The pressure setting should be checked periodically and adjusted if necessary. No specific service intervals are provided, but the valve should be inspected after any system changes or if abnormal pressure readings are observed. If the pressure gauge shows erratic readings or the valve fails to maintain the set pressure, it may require servicing or replacement.

Frequently asked questions

Can this valve be used in a domestic hot water system?
Yes, provided the system operates within the temperature and pressure limits specified. The maximum temperature of +40°C is suitable for most domestic hot water applications.

Is this valve suitable for use with antifreeze solutions?
Yes, the NBR sealing material is compatible with antifreeze solutions commonly used in heating systems.

Can the pressure setting be adjusted after installation?
Yes, the pressure can be adjusted using the adjustment screw on the valve body. It is recommended to use a calibrated pressure gauge for accurate settings.

What is the maximum allowable working pressure of this valve?
The valve is rated for PN 25, meaning it can handle a maximum working pressure of 25 bar under normal operating conditions.
