Ball cap with filter - FILTER BALL, 2" FF

Product detailed description

This ball valve with filter is commonly used in residential and commercial heating systems, plumbing installations, and irrigation circuits where particulate matter in the fluid stream can cause blockages or damage to downstream components. The valve combines a durable ball closure mechanism with a built-in filtration system, making it suitable for applications where regular maintenance is not feasible. Installers often use it in boiler circuits, pump lines, and domestic hot and cold water systems to protect sensitive equipment such as heat exchangers, thermostatic valves, and circulation pumps.

The FF (female-female) connection ensures compatibility with standard piping systems, while the CW602N brass body provides resistance to corrosion and mechanical stress. The valve is designed for use with water and is certified for potable water applications. The integrated filter element is designed to retain particles larger than 700 µm, reducing the risk of clogging in downstream components. The operating temperature range allows for use in both cold and hot water systems, with a pressure rating that adapts to the temperature conditions.

Technical parameters

The nominal pressure rating of PN 16 at +100°C indicates the valve's ability to handle standard operating pressures in most heating and plumbing systems. At higher temperatures of +150°C, the pressure rating reduces to PN 10, which is typical for brass components due to the material's thermal properties. These ratings are essential for correct sizing and system design, ensuring the valve can withstand the expected operating conditions without failure.

Installation and connection

Installation requires standard pipe-cutting and threading tools. The valve is connected using 2 inch FF (female-female) threads, which must be cleaned and checked for damage before assembly. Apply a suitable thread sealant or PTFE tape to ensure a leak-free connection. Ensure the valve is fully open during installation to prevent damage to the internal components. After installation, verify the tightness of the connections and perform a pressure test at the system's operating pressure to confirm integrity.

Common installation mistakes include using incorrect thread sealants incompatible with brass, over-tightening the connections, and failing to check for debris in the pipeline before installation. These can lead to leaks, thread damage, or premature failure of the sealing components.

Compatibility and accessories

This valve is compatible with standard copper, steel, and plastic piping systems that use FF thread connections. It is often used in conjunction with pressure-reducing valves, expansion vessels, and circulation pumps in heating systems. When installing in a new system, ensure that the upstream piping is clean and free of debris to reduce the frequency of filter maintenance. No additional accessories are required for basic installation, but a wrench suitable for brass components is recommended for tightening the connections.

Technical background for designers

The ball valve operates by rotating a solid ball with a central bore to control the flow of water. The ball is seated between two sealing surfaces, which are compressed by a tightening mechanism to ensure a leak-tight closure. The CW602N brass body offers good corrosion resistance and mechanical strength, making it suitable for long-term use in water systems. The integrated filter is made of a porous mesh material with a 700 µm pore size, which effectively removes larger particles from the flow. The filter should be positioned upstream of sensitive components to prevent clogging and ensure system efficiency.

The valve's performance is influenced by the quality of the incoming water, the frequency of flow changes, and the presence of suspended solids. Regular inspection of the filter element is recommended in systems with high particulate content to maintain optimal flow and prevent pressure drops.

Service and operation

Periodic inspection of the filter element is necessary in systems with high particulate content. The filter can be removed for cleaning or replacement without disassembling the entire valve. Check the sealing surfaces and the ball for signs of wear or damage, especially in systems with frequent flow changes. No specific service intervals are provided, but maintenance should be performed based on system performance and visual inspection.

Frequently asked questions

Can the ball valve with filter be used in a domestic hot water system?
Yes, the valve is suitable for domestic hot water systems with operating temperatures up to +150°C and a pressure rating of PN 10 at that temperature.

Is the filter element replaceable?
Yes, the filter element can be removed and replaced without disassembling the entire valve, allowing for maintenance without system shutdown.

What is the maximum operating pressure at 100°C?
The valve is rated for a maximum operating pressure of PN 16 at +100°C, which is suitable for most heating and plumbing applications.

Can the valve be used with PTFE tape for sealing?
Yes, PTFE tape is a suitable sealing material for the FF connections, provided it is applied correctly and not over-tightened to avoid damaging the threads.
