Full-bore isolation for water, heating and industrial circuits

MT gate valves provide full-bore, low-pressure-drop isolation for service lines that operate either fully open or fully closed. The rising stem visually signals position; the wedge-disc closure delivers leak-tight shut-off when seated. Brass range in CW617N for hydraulic service (DN8 to DN65, threaded F-F BSP per ISO 228) up to PN-16, -20 Β°C to +120 Β°C.

Cast iron range (GGG-40 / GG-25) with epoxy coating RAL 5013 and stainless-steel internals (stem, disc) for HVAC, fire protection and large-bore water distribution up to DN300 / PN-16. Flanged connections per EN 1092-2 (PN10/PN16). Designed for infrequent operation β€” when full flow with minimal pressure drop is required.
