The seller DN600 listing identifies a rising-stem parallel gate arrangement. Conflicting carbon-steel and stainless wording means the actual body material requires clarification.
Define the isolation duty, medium, pipe size, connections and operating conditions. Ask for the actual offered gate construction, body and sealing materials and operating arrangement with a drawing for the selected valve. Request the current catalogue or drawing for this item, and confirm the offered configuration and supporting documents with the company before specifying an order.
