The material combines the chemical resistance of engineering plastics with significantly greater rigidity and impact strength than standard PA, making it well suited to pool circulation lines, irrigation headers, and greenhouse fertigation systems where light weight and corrosion immunity are priorities over metal fittings.<\/p>\n<p>Both ports are 1 inch female BSP thread, allowing direct installation between standard male-threaded pipe adaptors or pump outlets without reducers. The spring-loaded NBR disc opens at a low cracking pressure of 0.025\u20130.035 bar, ensuring minimal restriction to forward flow at the rated capacity of 17.9 m\u00b3\/h, while closing reliably against system pressure up to 6 bar. The stainless steel 316 internal spring resists corrosion across the full operating temperature range of 0 \u00b0C to 70 \u00b0C, covering cold-water supply through warm pool return applications.<\/p>\n<h3>Dane techniczne<\/h3>\n<ul>\n<li>Typ \/ Seria: Amita<\/li>\n<li>\u015arednica nominalna: DN25<\/li>\n<li>Connection type: Female thread, 1 inch BSP (both ends)<\/li>\n<li>D\u0142ugo\u015b\u0107 ca\u0142kowita: 81 mm<\/li>\n<li>Body material: PA glass fibre reinforced (PA-GF), black<\/li>\n<li>Materia\u0142 spr\u0119\u017cyny: Stal nierdzewna 316<\/li>\n<li>Materia\u0142 uszczelki \/ tarczy: NBR<\/li>\n<li>Maksymalne ci\u015bnienie robocze: 6 bar\u00f3w<\/li>\n<li>Ci\u015bnienie otwarcia: 0.025\u20130.035 bar<\/li>\n<li>Maksymalny przep\u0142yw: 17.9 m\u00b3\/h<\/li>\n<li>Operating temperature range: 0 \u00b0C to 70 \u00b0C<\/li>\n<li>Kolor: czarny<\/li>\n<\/ul>\n<h3>Kompatybilno\u015b\u0107<\/h3>\n<p>Suitable for potable cold water, pool water, and irrigation systems using 1 inch BSP male-threaded pipe fittings or pump ports (DN25).
