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

Product detailed description

Indoor-outdoor ball valves are commonly used in residential and commercial buildings to manage water distribution systems that cross from internal infrastructure to external components such as garden taps, irrigation lines, or heating circuits. These valves ensure secure isolation of water flow and are essential in frost-prone areas where thermal expansion and contraction can affect pipe integrity. Installers working on central heating, plumbing, or irrigation systems often encounter these valves during maintenance, system upgrades, or new installations.

The extended-thread design of this model allows for precise alignment and secure sealing between the internal and external piping segments. The full-flow configuration minimises pressure loss, making it suitable for both low- and medium-pressure applications. This makes it ideal for use in domestic hot and cold water systems, as well as industrial systems where consistent flow rates are critical.

Technical parameters

Installation and connection

Installation begins with ensuring the pipeline is free of debris and properly aligned. The valve features internal and external FM threads (female-male), allowing it to connect directly to standard threaded fittings. Use appropriate sealing tape or compound on the threads to prevent leaks. A common mistake is misalignment of the extended thread, which can compromise the seal. Always verify that the valve is fully tightened and that the actuator is positioned for easy access. Confirm that the valve is installed in the correct orientation for the system layout, especially in systems with directional flow requirements.

Compatibility and accessories

This valve is compatible with standard water supply systems using threaded connections. It pairs effectively with other EVOLUTION series valves and fittings from IVAR. For optimal performance, ensure that the entire system uses compatible materials and thread types. Additional sealing compounds or gaskets may be required depending on the system’s specifications.

Technical background for designers

The valve operates via a rotating ball with a bore that aligns or blocks the flow path when turned. Its approval for potable water use means it meets strict health and safety standards. Integration into a system requires consideration of flow dynamics and pressure drops. The full-flow design reduces turbulence and maintains efficient flow, particularly beneficial in systems with high-volume demand.

Service and operation

Periodic inspection is recommended to ensure the valve remains leak-free and functions smoothly. Check for signs of corrosion or wear on the threads and body. If the valve shows resistance when turning, disassemble and clean the internal components if necessary. No specific service intervals are provided in the brief, but routine checks should be included in maintenance schedules for critical systems.

Frequently asked questions

Can this valve be used in a frost-prone area?
Yes, the valve is rated for operation down to -20°C and up to +120°C, making it suitable for locations exposed to freezing conditions.

Is the valve suitable for potable water?
Yes, the nickel-plated brass body is certified for use with drinking water according to the relevant standards.

Can the valve be installed in a vertical position?
Yes, provided the system allows for unrestricted movement of the actuator and that the internal components remain unobstructed by sediment or debris.

What sealing method should be used during installation?
Apply thread sealant or PTFE tape to the FM threads to ensure a watertight connection and avoid over-tightening, which could damage the threads.
