Coliter®’s flange gate valves are precision-engineered for demanding applications in chemical processing, pharmaceuticals, food & beverage, and marine environments where corrosion resistance and leak-tight performance are critical. The series includes the Z41W stainless steel rising stem gate valve, Z45H non-rising stem type with metal seat, Z45T soft-seated variant, and advanced ZJM45X/Z45X soft seal densified models—all featuring CF8/CF8M (304/316) stainless steel bodies, full-port design, and flanged ends per PN16 (DN15–DN300) or ANSI 150# standards. With operating temperatures up to 180°C (soft seal) or 425°C (metal seal), these valves deliver zero leakage, smooth operation, and long service life in aggressive media, high-purity water, and steam systems.
