Ball cap with filter - FILTER BALL, 1/2" FF

Product detailed description

Ball valves with integrated filters are essential components in heating, plumbing, and sanitary systems where particulate control is necessary. These valves are commonly installed in residential and commercial buildings, including apartment complexes, industrial facilities, and commercial kitchens. They are used in closed-loop systems, domestic hot water circuits, and pump circuits where debris accumulation can cause blockages or damage to downstream components. Installers often encounter these valves in systems where maintenance intervals require quick isolation and cleaning without system shutdown.

These valves are typically installed in locations where sediment or particulate matter may be present in the water supply. The integrated filter helps prevent clogging of downstream components such as thermostatic valves, heat exchangers, and flow meters. The compact design allows for installation in tight spaces, and the lever handle provides a clear indication of the valve’s open or closed position.

Technical parameters

Brand	IVAR

The nominal pressure rating of PN 16 at 100°C indicates the valve is suitable for medium-pressure systems operating at moderate temperatures. At higher temperatures of 150°C, the pressure rating reduces to PN 10, which is important for sizing and selecting the correct valve for the intended operating conditions. The 700 µm filter mesh ensures that particles larger than 0.7 mm are retained, preventing them from entering sensitive system components. These parameters are essential for ensuring the valve operates safely and effectively within its design limits.

Installation and connection

The valve is equipped with internal female threads (FF) on both ends, allowing for direct connection to standard piping systems. The 1/2 inch size is commonly used in domestic and light commercial applications. Before installation, the installer should verify that the pipe threads are clean and undamaged to ensure a leak-free connection. The lever handle should be aligned with the flow direction for an open position and perpendicular for a closed position. A common mistake is incorrect orientation of the valve, which can lead to improper sealing or operational inefficiency. The valve should be tightened using a wrench, ensuring that the sealing surface is not over-torqued, which could damage the seating surface or gasket.

Compatibility and accessories

This valve is compatible with standard copper, steel, and plastic piping systems that use 1/2 inch FF connections. It is suitable for use with potable water and is certified for such applications. No additional accessories are required for standard installation, although pipe fittings such as unions or adapters may be necessary depending on the system configuration. No related products are recommended for this model.

Technical background for designers

The valve operates on a standard ball valve principle, where a pivoting ball with a bore controls the flow of water. The integrated filter is a porous metal mesh that traps particulate matter. The body is made from CW602N brass, a lead-free alloy known for its corrosion resistance and mechanical strength. The absence of silicone in the sealing materials ensures compatibility with potable water standards. The valve is designed to be installed in systems where periodic maintenance is required, and the filter can be cleaned without removing the entire valve. The operating life is influenced by the quality of the water supply and the frequency of maintenance. High particulate load or aggressive water chemistry can reduce the efficiency and lifespan of the filter element.

Service and operation

The valve is designed for regular maintenance, with the filter element being accessible for cleaning. The lever handle allows for quick isolation of the flow, and the valve can be opened or closed without the need for tools. No specific service intervals are provided, but the filter should be inspected and cleaned periodically, depending on the water quality and system usage. During operation, the installer should check for signs of leakage, particularly at the connection points and around the lever handle. A properly installed and maintained valve ensures reliable operation and minimises the risk of system failure due to blockage or corrosion.

Frequently asked questions

Can the filter be removed for cleaning?
Yes, the filter element is accessible and can be cleaned without removing the entire valve from the system. This allows for quick maintenance without system downtime.

Is this valve suitable for use in potable water systems?
Yes, the valve is certified for potable water applications and constructed from materials that comply with relevant water safety standards.

Can this valve be used in systems with temperatures above 150°C?
No, the pressure rating reduces to PN 10 at 150°C, and the valve is not recommended for continuous use above this temperature without consulting the manufacturer’s technical data sheet.

What is the maximum particle size that the filter can retain?
The filter mesh has a porosity of 700 µm, meaning it retains particles larger than 0.7 mm. This is suitable for general particulate control in water systems.
