Brass & Polymer Switch Valve (Security Isolation Valve)

Информация о продукте

The Brass & Polymer Switch Valve (SWV-Series) is a secure isolation valve engineered for potable water distribution networks, residential plumbing, and irrigation systems. Manufactured through hot forging technology, the brass valve uses a nickel-plated brass ball to ensure smooth and corrosion-resistant performance. The brass body meets DIN seventeen-thousand-six-hundred-sixty international standards. The valve is designed to withstand hydrostatic pressure according to INSO sixteen-thousand-two-hundred-twenty-two and BS EN thirteen-thousand-eight-hundred-twenty-eight international standards. Equipped with a special wrench mechanism, it prevents unauthorized operation, making it ideal for applications requiring restricted valve access. The sealing components comply with BS EN six-hundred-eighty-one for high-quality water-tight performance. The polymer-coated brass version offers enhanced corrosion resistance and reduced installation costs while maintaining the same mechanical reliability. Both versions are available in half-inch sizes.
