Ball cap with filter - FILTER BALL, 5/4" FF

Product detailed description

This ball valve with filter is commonly used in residential and commercial heating, plumbing and sanitation systems. It is installed in circuits where media purity is essential, such as in domestic hot water lines, underfloor heating manifolds or in systems with sensitive downstream equipment. The compact design allows for installation in tight spaces, such as mechanical rooms or behind wall panels. The integrated filter prevents particulate matter from entering the system, reducing the risk of clogging in radiators, heat exchangers or pumps.

Typical applications include central heating systems, domestic hot water circuits and industrial process lines where particulate contamination is a concern. The valve is often used in conjunction with circulation pumps, expansion vessels or pressure-reducing valves. The operating temperature range is defined by the pressure rating, with PN 16 at 100°C and PN 10 at 150°C. This makes it suitable for both low-temperature and high-temperature systems, provided the pressure conditions are met.

The nominal pressure rating (PN 16 at 100°C) is a key factor in system design, ensuring the valve can handle the expected pressure and temperature conditions. The mesh size of 700 µm determines the particle retention capability, which is important for protecting downstream components. The internal thread (FF) allows for direct connection to standard pipe fittings without the need for adapters.Installation and connection This valve is installed using standard pipe-threading tools. The 5/4 inch FF connection requires matching internal threads on the pipe ends. Before tightening, ensure that the sealing material is compatible with the system media and operating conditions. A common mistake is over-tightening, which can damage the sealing surface or the valve body. Always verify that the valve is fully open during installation to avoid stress on the sealing components. After installation, perform a leak test by pressurising the system and inspecting the connection points for any signs of seepage.Compatibility and accessories This valve is compatible with standard copper or steel pipes with 5/4 inch FF threads. It can be used in conjunction with pressure-reducing valves, circulation pumps and expansion vessels. For systems requiring remote operation, an actuator can be added to the lever. No additional accessories are required for basic installation, but a sealing tape or compound should be used on the threads to ensure a leak-free connection.Technical background for designers The ball valve operates via a pivoting ball with a central bore that aligns with the flow direction when open. The integrated filter is a mesh screen with a 700 µm aperture, capturing particles larger than this size. The body is made from brass CW602N, a lead-free alloy suitable for potable water applications. The lever is designed for manual operation and can be adjusted to a fixed position. The valve’s performance is influenced by the media viscosity, temperature and the presence of abrasive particles. Regular cleaning of the filter is necessary to maintain flow efficiency and prevent pressure drop.Service and operation Routine maintenance includes inspecting the filter for clogging and cleaning it with a soft brush or compressed air. The valve should be checked for leaks after installation and at regular intervals during operation. If the filter becomes clogged, it can be removed for cleaning without disassembling the entire valve. No lubrication is required for the ball mechanism. If the sealing surface becomes damaged, the valve can be disassembled and the sealing components replaced.Frequently asked questions

Can this valve be used in potable water systems?
Yes, it is certified for potable water applications and constructed from materials that do not contaminate the water.

What is the maximum operating temperature?
At 100°C, the valve operates at PN 16, and at 150°C, the pressure rating reduces to PN 10.

Is the filter removable for cleaning?
Yes, the filter can be removed for cleaning without disassembling the entire valve.

Can this valve be connected to a 5/4 inch FF pipe?
Yes, the valve has a 5/4 inch FF internal thread for direct connection to compatible pipe fittings.
