Gv. indoor - outdoor, 5/4" MF, butterfly

Product detailed description

This ball valve is commonly used in plumbing and heating systems where a reliable shut-off is required in both indoor and outdoor environments. It is suitable for applications involving water, air, and other non-aggressive media. The valve is designed for use in residential and commercial buildings, including systems that require resistance to low temperatures and frequent operation. The installation involves ensuring correct alignment and avoiding mechanical stress on the valve body to maintain performance and longevity.

Technical parameters

Installation and connection

Installation requires connecting the valve between external and internal male threads (MF) of 5/4 inch. Ensure the pipeline is aligned to avoid bending stress on the valve body. The valve must not be subjected to impacts or forced disassembly. A minimum distance of 20 cm should be maintained between the valve and any welding points to prevent heat damage. Check that the valve is fully aligned with the pipeline to prevent leakage and mechanical stress. Common installation mistakes include incorrect thread orientation, insufficient alignment, and welding too close to the valve body.

Compatibility and accessories

This valve is compatible with standard water and air distribution systems using 5/4 inch MF threaded connections. No additional accessories are required for standard installation. Ensure the system is designed to accommodate the valve's dimensions and operating parameters. No related products are specified for this model.

Technical background for designers

The valve operates using a specially shaped ball with surface depressions that reduce contact area with the sealing seat. This design minimises the accumulation of deposits and debris during operation. The CW617N nickel-plated brass body provides corrosion resistance and durability in water systems. The valve is fully sealed and cannot be disassembled for maintenance. The sealing integrity is maintained through the use of a fixed body design, ensuring long-term reliability in both indoor and outdoor conditions. The valve's performance is influenced by correct installation, system alignment, and adherence to temperature limits.

Service and operation

Regular operation is recommended to prevent the accumulation of deposits on the ball. In water systems, the valve should be cycled through its full range of motion at least once every six months. The valve is not designed for disassembly or maintenance. Any damage to the valve, excluding the lever or stem, requires replacement with a new unit. The valve must not be exposed to temperatures exceeding 185°C. Ensure the system is designed to avoid mechanical stress on the valve body during operation.

Frequently asked questions

Can this valve be used in outdoor water supply systems?
Yes, the valve is suitable for outdoor use due to its temperature range and construction from nickel-plated brass approved for potable water.

Is it possible to disassemble the valve for inspection?
No, the valve is designed as a sealed unit and cannot be disassembled. Any damage must be addressed by replacing the entire unit.

What is the maximum allowable temperature for this valve?
The maximum allowable temperature is +120°C during normal operation and 185°C as a limit for short-term exposure.

Can the valve be used in systems with aggressive media?
No, the valve is designed for non-aggressive media such as water and air. Use in systems with aggressive media is not recommended.
