Gv. indoor - indoor, 1" FF, butterfly

Product detailed description

This indoor-to-indoor butterfly ball valve is commonly used in residential and commercial plumbing systems for water shut-off applications. Installers working on central heating, domestic hot and cold water supply, and irrigation systems will find this valve suitable for branch isolation and system maintenance. The compact design allows for installation in tight spaces such as under sinks, behind panels or within mechanical rooms.

The valve operates effectively in both heating and cooling applications where water is the primary medium. It is particularly useful in systems where frequent isolation of pipe sections is required during repairs or maintenance. The sealing mechanism ensures minimal leakage when closed and maintains integrity over repeated operation cycles.

Technical parameters

Installation and connection

Before installation, ensure the pipe ends are clean and free from burrs. The 1 inch female-female (FF) thread requires standard pipe sealing methods such as PTFE tape or thread sealant. Apply even pressure when tightening the connections to avoid damaging the valve body or sealing surfaces. Check that the valve is fully aligned with the pipeline axis to prevent stress on the threads.

Compatibility and accessories

This valve is compatible with standard copper or steel piping systems using 1 inch FF threaded connections. For complete system functionality, ensure that adjacent fittings and pipe sections also support the PN 25 rating. No additional accessories are required for basic installation, though pipe supports may be needed depending on the installation location and pipe length.

Technical background for designers

The butterfly ball valve operates via a rotating disc that aligns with the flow path when open and blocks it when closed. The nickel-plated CW617N brass body provides resistance to corrosion and ensures long-term durability in water systems. The material’s compatibility with potable water standards makes it suitable for applications involving drinking water. The valve integrates into systems requiring high shut-off reliability without significant pressure drop. Its performance is influenced by the quality of installation, correct alignment, and the condition of the sealing surfaces.

Service and operation

Regular inspection of the valve should include checking for leaks at the connections and verifying smooth operation of the handle. Ensure that the valve can be opened and closed without resistance, indicating no internal blockage or wear. No scheduled maintenance intervals are specified in the provided data. If the valve shows signs of leakage or operational stiffness, disassembly and inspection may be required to assess internal components.

Frequently asked questions

Can this valve be used in a domestic hot water system?
Yes, it is suitable for hot water systems with temperatures up to +120°C as indicated by the operating range.

Is this valve compatible with copper piping?
Yes, the FF threaded connection is compatible with copper pipes of appropriate size and thread type.

Does the nickel plating affect the sealing properties?
No, the plating serves primarily to protect against corrosion and does not interfere with the sealing surfaces.

Can this valve be used in a closed-loop heating system?
Yes, provided the system operates within the specified pressure and temperature limits.
