Chrome-Plated Brass Ball Valve 90° Elbow Male/Female 3/4''

Chrome-Plated Brass Ball Valve 90° Elbow Male/Female 3/4'' (Reference: 298-34)

This professional-grade ball valve combines strength and reliability for all your irrigation and hydraulic installation needs. Made from OT58 brass with a chrome finish, it provides exceptional resistance to corrosion and weathering. Its 3/4'' male/female elbow configuration with union fitting makes installation easy in tight spaces while ensuring a perfect seal. ACS and CE certified, it is perfectly suited for food-grade applications and meets the strictest European standards.

Applications and Benefits

This shut-off valve is particularly well-suited for automatic irrigation systems, domestic water network installations, and light industrial applications. Its elbow design makes it ideal for corner connections, under sinks, or in technical access chambers where space is limited. Professional gardeners and homeowners alike appreciate its red butterfly handle, which allows easy operation even with work gloves on.

The full bore design ensures optimal flow with no pressure drop, essential for maintaining constant pressure in your irrigation systems. This feature makes it a preferred choice for drip systems, rotary sprinklers, and micro-spray installations that require precise flow control.

Technical Specifications and Materials

The fully OT58 brass construction (body, ball, and stem) gives this valve exceptional resistance to corrosion and thermal variations. The chrome coating reinforces this protection while providing a lasting aesthetic finish that resists scratches and oxidation.

The PTFE seats (Teflon) ensure a perfect seal and optimal chemical resistance, while the EPDM O-rings guarantee superior durability at extreme temperatures (-40°C to +120°C). The double O-ring technology on the stem eliminates any risk of leakage, even after thousands of operations.

The ISO228 thread ensures universal compatibility with all standard fittings on the market. The nominal pressure rating PN32 (32 bar) allows use in high-pressure installations without risk of failure.

Installation and Use

Installation of this elbow valve is simplified by its union fitting, which allows easy disassembly without unscrewing adjacent pipework. Use thread sealant paste or PTFE tape on the threads to ensure a perfect seal. Tighten firmly but without excess to avoid damaging the seals.

The butterfly handle allows quick opening and closing with a simple quarter turn (90°). In the closed position, the handle is perpendicular to the valve axis, and in the open position, it is aligned with it. This intuitive design prevents any confusion during operation.

For maintenance, simply clean the chrome surface regularly with a soft cloth and a non-abrasive degreasing product. Periodic lubrication of the internal mechanism is not necessary thanks to the self-lubricating materials used.

Expert Tips and Product Synergies

To optimise your irrigation installation, pair this valve with our Camlock or Express fittings for quick and watertight connections. In frost-prone regions, install this valve in a protected access chamber or use our heating cables to prevent pipe bursts.

A professional tip is to install several valves in series to create independent irrigation zones in your garden. Combine it with our Gardena programmers to fully automate your irrigation system.

For industrial applications, this valve can be integrated into cooling or heating circuits thanks to its high operating temperature (120°C). However, avoid sudden thermal shocks that could affect the seal integrity.

The presence of the batch number and production date engraved on the body facilitates traceability and quality monitoring, a valuable asset for professional installations subject to inspection.
