Application: The spectacle valve is used in gas pipelines of blast furnace, converter and coke oven gas.

Max. working pressure: 0.25 MPa to DN 1400

Max. working temperature: 250 ° C (sealing Silicone)

Technical description: Ecological eyeglass valve consists of a body and two side casings screwed to the body, a movable sealing board, a clamping device and a stroke drive. The pressing of the sealing surfaces to the sealing board is carried out automatically by means of Belleville springs. The movement of the board is controlled using a strong chain and chain sprocket. The end positions of the board are optically visible, and in addition are protected by limit switches. The individual hydraulic circuits are switched off automatically.

Management: Moving can be carried out hydraulically, pressing and releasing the board is possible only hydraulically. The hydraulic control system is part of the supply of valves. In an emergency, you can control the valve manually.

Применение: Очковая задвижка применяется в газопроводах доменного, конверторного и коксового газа.
