Ball valve water - with drainage - 6/4 "FF; lever FIV.08011

Product detailed description

This ball valve with drainage is commonly used in residential and commercial water supply lines, including heating and sanitation systems. Installers typically fit it in locations requiring frequent shut-off and drainage, such as riser pipes, meter chambers or branch lines. The nickel-plated brass construction ensures resistance to corrosion and scaling, making it suitable for both cold and warm water applications. The lever design allows for quick manual operation and clear valve position indication.

The internal threading (Innen FF) simplifies installation in standard pipe systems, while the drainage feature facilitates system maintenance by allowing controlled emptying of trapped water. This makes the valve ideal for use in frost-prone areas or during seasonal system shutdowns. It is often found in central heating systems, circulation loops and building automation systems where precise flow control and isolation are essential.

Technical parameters

Material	Nickel-plated brass CW617N
Nominal pressure	PN 25
Code	I08011112
Brand	IVAR

The nominal pressure rating of PN 25 indicates the valve can handle continuous pressures up to 25 bar at room temperature. This is important when selecting components for high-pressure applications such as circulation pumps or pressurised storage tanks. The material specification (nickel-plated brass CW617N) determines its chemical resistance and mechanical strength under varying operational conditions.

Installation and connection

This valve features internal female threading (Innen FF), compatible with standard copper or steel pipes. Before fitting, ensure the thread size matches the pipeline dimensions. Use a sealing compound or PTFE tape to prevent leaks. The lever mechanism should be positioned for easy access and full rotation. After installation, verify tightness by opening and closing the valve while monitoring for seepage. Common errors include incorrect thread alignment or over-tightening, which can damage the sealing surface or lever pivot.

Compatibility and accessories

This ball valve is suitable for integration with standard water distribution systems and compatible with most pipe insulation methods. For complex installations involving multiple valves or control systems, additional components such as isolation switches or pressure gauges may be required. Due to the absence of listed alternatives, consult the manufacturer’s technical documentation for recommended combinations with other IVAR components.

Technical background for designers

The valve operates via a rotating ball with a bore aligned with the flow direction when open. The nickel-plated brass body resists oxidation and maintains structural integrity under thermal expansion and contraction. Its PN 25 rating ensures suitability for pressurised systems, while the drainage port allows controlled release of residual water to prevent freezing or blockages. The lever design reduces actuation force compared to handwheel variants, improving usability in confined spaces. Long-term performance depends on the quality of the sealing surface and the absence of particulate matter in the fluid stream.

Service and operation

Routine checks should focus on the lever movement and the condition of the sealing threads. Any stiffness or irregular motion may indicate internal wear or debris accumulation. Clean the drainage port periodically to avoid clogging. While no scheduled service intervals are specified, immediate inspection is advised after prolonged non-use or exposure to extreme temperatures. Ensure the valve is fully closed during draining to prevent uncontrolled flow.

Frequently asked questions

Can this ball valve be used in hot water systems?
Yes, it is rated for use in hot water systems with a maximum operating temperature of +80°C. The nickel-plated brass construction ensures stability under thermal stress.

Is this valve suitable for installation in underground water lines?
It is designed for above-ground use due to its mechanical lever operation. Underground installations require protective enclosures to prevent lever damage and environmental corrosion.

Does the drainage function operate independently from the main valve?
Yes, the drainage port can be opened separately from the main flow path, enabling controlled emptying of the system without fully closing the valve.

Can this model be replaced with a motorised variant for remote control?
No, the lever operation is fixed and cannot be modified for motorised control. For automated systems, consult the manufacturer for compatible motorised models.
