Gv. indoor - outdoor, 1/4" FM, butterfly

Product detailed description

Ball valves of the EVOLUTION series are commonly used in residential and commercial buildings for controlling water flow in heating, plumbing, and sanitation systems. This model is specifically designed for applications involving both internal and external connections, such as pipe transitions between indoor and outdoor environments. It is often found in domestic hot and cold water lines, where the need for reliable sealing under varying temperatures is critical. The extended thread ensures proper alignment and leak-free performance during installation.

The valve is suited for systems that operate within a wide temperature range, particularly in regions with freezing conditions. Installers should ensure that the system includes expansion joints or flexible couplings when connecting to rigid piping to accommodate thermal movement and prevent stress on the valve body.

Technical parameters

Material	Nickel-plated brass CW617N ATEST for potable water
Operating temperature	-20 °C
Nominal pressure	PN 50
Weight	0.14 kg
Code	80004015
Brand	IVAR

The PN 50 pressure rating indicates that the valve can handle high-pressure water systems, making it suitable for pressurised mains and closed-loop circuits. The operating temperature range from -20°C to +120°C means it can be used in both chilled and heated water systems. These parameters are essential for ensuring correct valve selection based on the system’s hydraulic and thermal requirements.

Installation and connection

To install the IVAR 80004015, first inspect the threads of both the valve and the pipe for damage or debris. Apply a suitable thread sealant compatible with potable water systems. The valve connects via a 1/4 inch female metric thread (FM) on one side and an external thread on the other. Ensure the valve is fully open before tightening to avoid over-torquing the stem. After installation, verify the tightness of all connections using a wrench, but avoid excessive force which could deform the threads. A common mistake is neglecting to align the valve correctly with the pipeline axis, which can cause misalignment and leakage over time.

Compatibility and accessories

This valve is compatible with standard water supply systems and can be paired with copper, PPR, or steel pipes using appropriate fittings. When connecting to plastic or composite materials, ensure that the thread type matches the pipe fitting. For systems requiring additional isolation or pressure regulation, consider installing upstream pressure-reducing valves or filters. Related products include other EVOLUTION series ball valves from IVAR, but no specific alternatives are provided.

Technical background for designers

This ball valve operates via a rotating spherical disc with a through-hole that allows full flow when aligned with the pipeline. The nickel-plated brass body offers corrosion resistance and durability in potable water systems. The CW617N alloy provides mechanical strength while meeting the ATEST certification for drinking water safety. The extended butterfly-style lever ensures ease of operation even in confined spaces. Proper integration requires ensuring that the valve is positioned for easy access and that the surrounding system minimises thermal stress and vibration that could affect long-term performance.

Service and operation

Routine inspection should focus on checking for leaks at the thread connections and verifying smooth operation of the lever. No scheduled service intervals are specified in the technical documentation. If the valve becomes stiff or difficult to turn, disassembly and cleaning of the stem mechanism may be required. In cases of suspected internal wear, replacement is recommended rather than repair to maintain system integrity.

Frequently asked questions

Can the IVAR 80004015 be used in underground water supply lines?
Yes, provided the installation is protected against direct soil contact and mechanical damage. The valve is suitable for internal-to-external connections but not for fully submerged use.

Is this valve suitable for use with chemical solutions other than potable water?
No, the technical data sheet specifies compatibility only with potable water. Using it with aggressive chemicals may void the warranty and compromise the seal integrity.

How does the extended butterfly lever affect torque requirements?
The lever is designed to provide sufficient mechanical advantage for manual operation without the need for additional tools under normal working conditions.

Can this model be replaced with a similar IVAR ball valve of a different size?
Replacement with a different size is possible only if the new valve maintains the same thread type and pressure rating. Always refer to the system design specifications before changing components.
