ISI-Certified 25mm Ball Valve (IS 9890)<\/span><\/h1>\n
\n

Overview<\/span><\/h2>\n

The\u00a0<\/span>ISI-Certified 25mm Ball Valve<\/span><\/strong>\u00a0is a precision-engineered, general-purpose flow control device designed for reliable on\/off operation in water, air, oil, and other fluid systems. Bearing the prestigious\u00a0<\/span>ISI Mark<\/span><\/strong>\u00a0\u2014 a certification from the\u00a0<\/span>Bureau of Indian Standards (BIS)<\/span><\/strong>\u00a0\u2014 this valve conforms to\u00a0<\/span>IS 9890:1981 (Specification for General Purpose Ball Valves)<\/span><\/strong>\u00a0, ensuring quality, safety, and performance you can trust<\/span>.<\/span><\/p>\n

A ball valve is a quarter-turn valve that uses a spherical disc (the ball) with a cylindrical bore to control flow. When the handle is turned 90 degrees, the bore aligns with the pipeline, allowing full flow; when turned back, the bore is perpendicular, completely shutting off flow. This simple yet effective mechanism provides reliable shut-off with minimal pressure drop and long service life.<\/span><\/p>\n

Available in multiple materials including\u00a0<\/span>Brass<\/span><\/strong>,\u00a0<\/span>Gun Metal<\/span><\/strong>,\u00a0<\/span>Cast Iron<\/span><\/strong>, and\u00a0<\/span>Stainless Steel<\/span><\/strong>, with either\u00a0<\/span>Full Bore<\/span><\/strong>\u00a0or\u00a0<\/span>Standard Bore<\/span><\/strong>\u00a0construction, the ISI-Certified 25mm Ball Valve offers the durability and performance you need for plumbing, water supply, industrial processing, and fire-fighting applications<\/span>.<\/span><\/p>\n
