Pressure reducing valve - with fitting and pressure gauge - 1 "MM IVAR.5350

Product detailed description

Pressure reducing valves are essential in water supply systems where mains pressure exceeds the safe operating range of downstream components. This model is commonly used in residential, commercial and light industrial applications to regulate pressure in domestic water lines, heating circuits and irrigation systems. It is particularly suited for installations where pressure stability is critical for the longevity of fixtures and appliances. The inclusion of a pressure gauge allows for real-time monitoring of the output pressure, ensuring accurate adjustment and system performance.

Correct selection of pressure reducing valves depends on system requirements such as inlet pressure, flow rate and media type. This model is designed for use with potable and non-potable water systems, and its brass construction ensures resistance to corrosion and mechanical stress. The adjustable range and gauge make it suitable for systems requiring precise pressure control.

The nominal pressure rating of PN25 indicates the valve is suitable for systems with a maximum working pressure of 25 bar. The operating temperature limit of +40°C means it is appropriate for cold water applications and systems where temperature does not exceed this threshold. The material, brass CW602N, is a standard alloy for water system components due to its durability and resistance to wear. These parameters are essential for ensuring compatibility with existing piping and for determining the valve’s suitability for a specific installation.

Installation and connection

The valve is designed for installation in water lines where pressure reduction is required. It features external metric threads for connection to the supply and outlet piping. The fitting includes a union for ease of installation and future maintenance. Installers should ensure that the inlet and outlet ports are correctly aligned with the direction of flow indicated on the valve body. A common mistake is reversing the direction of flow, which can lead to improper operation or damage. The pressure gauge should be checked for correct orientation and secure mounting to ensure accurate readings. Prior to installation, the system should be isolated and drained to prevent water ingress during fitting.

Compatibility and accessories

This pressure reducing valve is compatible with standard water supply systems using metric threaded connections. It is typically used in conjunction with isolation valves, pressure vessels and expansion tanks in domestic and industrial water systems. No additional accessories are included in the standard package. For complete system integration, installers may need to order isolation valves, unions or pressure relief valves separately. The valve is not designed for use with steam or high-temperature media.

Technical background for designers

The operating principle of this valve is based on a diaphragm mechanism that adjusts the opening in response to the set pressure. The NBR sealing material provides a flexible and durable seal against the valve seat. The brass body ensures structural integrity and resistance to corrosion in water environments. The integration of a pressure gauge allows for real-time monitoring of the reduced pressure, which is essential for maintaining system performance. The service life of the valve is influenced by the quality of the water, the frequency of pressure fluctuations and the accuracy of the initial adjustment. Proper installation and regular inspection are key to maintaining efficiency and preventing leaks or failures.

Service and operation

The valve requires minimal maintenance but should be periodically inspected for signs of wear, leakage or blockage. The pressure gauge should be checked for accuracy and replaced if it shows signs of inaccuracy or damage. The sealing material may degrade over time, especially in systems with high mineral content or frequent pressure surges. If the valve shows signs of reduced performance, such as inconsistent pressure output, it should be isolated and inspected for internal damage. No specific service intervals are provided in the technical data, but regular visual and functional checks are recommended as part of routine system maintenance.

Frequently asked questions

Can this valve be used in a domestic hot water system?
No, the operating temperature limit of +40°C makes it unsuitable for hot water applications. A higher temperature-rated model would be required.

Is the pressure gauge adjustable?
No, the gauge is fixed and provides a readout of the output pressure. Adjustment of the reduced pressure is done via the valve body, not the gauge itself.

Can this valve be installed vertically?
Yes, the valve can be installed in either horizontal or vertical orientations, provided the flow direction is maintained as indicated on the body.

What is the maximum inlet pressure for this model?
The nominal pressure rating of PN25 indicates the valve is suitable for systems with a maximum working pressure of 25 bar.
