Gv. indoor - indoor, 5/4" FF, butterfly

Product detailed description

This butterfly-style ball valve is commonly used in heating, plumbing and irrigation systems to control the flow of water in medium-pressure environments. It is frequently installed in industrial and commercial buildings such as factories, warehouses, offices and multi-unit residential complexes. The valve is typically found in systems that require reliable shut-off with minimal pressure loss, such as central heating circuits, hot water supply lines and pump stations. Installers should ensure that the system conditions match the valve’s operating parameters before fitting.

The valve is designed for use with potable water and is suitable for both new installations and system upgrades. Its internal-thread connection allows for straightforward integration into existing pipe networks, while the butterfly handle provides easy manual operation. The valve is often used in conjunction with other components such as pressure-reducing valves, filters and flow meters to maintain system integrity and performance.

Technical parameters

The operating temperature range of -20 °C to +120 °C makes this valve suitable for cold and hot water applications. The PN 25 rating indicates that it can handle medium-pressure systems, which is important when selecting the correct component for a given hydraulic design. The nickel-plated brass construction ensures durability and resistance to corrosion, especially in water systems where chemical stability is required. These parameters help determine whether the valve is appropriate for a specific installation based on system pressure, fluid type and environmental conditions.

Installation and connection

The valve is equipped with internal-thread connections on both ends, allowing it to be fitted directly into standard pipe fittings. Prior to installation, the threads should be cleaned and checked for damage. A thread sealant or PTFE tape should be applied to ensure a leak-free connection. The extended threaded stem allows for easier access to the operating handle in tight spaces. When positioning the valve, ensure that it is aligned with the direction of flow indicated on the body. Common installation errors include incorrect orientation, insufficient sealing material and failure to check the alignment of the valve with the pipeline.

Compatibility and accessories

This valve is compatible with copper, steel and polypropylene piping systems that use internal-thread fittings. It should be used in conjunction with standard pipe fittings such as unions, elbows and tees to facilitate installation and future maintenance. No additional accessories are required unless specified by the system design. There are no related products listed for this model.

Technical background for designers

The ball valve operates using a rotating ball with a through-hole that aligns with the inlet and outlet ports to allow or block flow. The ball is seated within a housing made of nickel-plated brass CW617N, which is certified for use with potable water. This material offers high mechanical strength and resistance to corrosion, making it suitable for long-term use in water systems. The valve integrates into the system without requiring additional flow regulation devices due to its full-bore design, which minimises pressure drop. The service life and efficiency depend on the quality of installation, the cleanliness of the fluid and the absence of excessive vibration or thermal cycling.

Service and operation

Periodic visual inspections are recommended to check for signs of leakage, corrosion or mechanical wear. The valve does not require scheduled maintenance under normal operating conditions. If the handle becomes difficult to turn, it may indicate internal wear or debris accumulation, and the valve should be disassembled for cleaning. No service intervals are specified in the provided data.

Frequently asked questions

Can this valve be used in a domestic hot water system?
Yes, the valve is suitable for hot water applications with a maximum temperature of +120 °C, making it appropriate for domestic systems.

Is the valve compatible with copper pipe fittings?
Yes, the internal-thread connection allows it to be used with copper pipe fittings that have matching thread profiles.

Can the valve be installed in a vertical position?
Yes, the valve can be installed vertically as long as the direction of flow is aligned with the marking on the body.

Does the valve require a special gasket for installation?
No, a standard thread sealant or PTFE tape is sufficient for sealing the connection.
