Universal butterfly valve 6/4" full range

Product detailed description

Universal butterfly valves are commonly used in heating and plumbing systems to regulate flow in hot water circuits. This model is suitable for installations in residential and commercial buildings, including central heating systems, hot water distribution lines and industrial applications. Installers typically work with these valves during system design, commissioning and maintenance phases. The valve is intended for use in closed-loop systems where controlled flow regulation is required.

Its compact dimensions and robust brass construction make it ideal for tight spaces and high-temperature environments. The internal thread allows for direct connection to standard piping systems, reducing the need for additional fittings. The valve’s design ensures reliable sealing and smooth operation, even under fluctuating pressure conditions.

The valve is rated for a nominal pressure of PN15 and is tested to 40 bar, making it suitable for medium-pressure systems. The maximum operating temperature is 100°C, which is typical for hot water and heating applications. The opening pressure of 0.02 bar indicates the minimal pressure required for the valve to function correctly. These parameters are essential for correct sizing and selection in accordance with system requirements.

Installation and connection

The valve is installed using an internal thread connection, which must be aligned with the corresponding pipe thread. Before installation, ensure the thread is clean and free of debris. Apply a suitable thread sealant to prevent leaks. The valve should be mounted in a position that allows easy access for inspection and maintenance. Avoid over-tightening the connection to prevent damage to the threads or the valve body. Common installation errors include misalignment of the valve body and incorrect orientation, which can lead to improper sealing or restricted flow. Always verify the direction of flow indicated on the valve body.

Compatibility and accessories

This universal butterfly valve is compatible with standard threaded piping systems. It is typically used in conjunction with other components such as pressure regulators, expansion vessels and flow meters. For complete system functionality, additional accessories such as unions or sealing rings may be required, depending on the installation method. No specific related products are listed for this model.

Technical background for designers

The valve operates on a simple mechanical principle: a disc positioned perpendicular to the flow path opens or closes the passage when rotated. The disc is made of brass OT 58, a material known for its durability and resistance to corrosion in hot water environments. The internal thread ensures secure and leak-free connections within the system. The valve is designed to integrate seamlessly into hot water and heating systems, with its pressure and temperature ratings ensuring long-term performance. The service life and efficiency depend on regular maintenance and correct installation, as well as the quality of the surrounding system components.

Service and operation

Routine checks should include inspecting the valve for signs of wear, leakage or blockage. The sealing surface should remain clean and undamaged. If the valve shows signs of reduced sealing effectiveness or unusual noise, it should be inspected further. No specific service intervals are provided in the brief. In case of failure, the entire unit may need to be replaced, as repairs are not typically performed in the field.
