Principle: 

Bodies and bonnets are high quality cast and afterwards precisely machined, directing the attention to prevent stress concentration. The bodies of carbon steel gate valves consist of a straight through port that guarantees minimal turbulence and resistance to flow. In both designs, bolted bonnet and pressure seal, the bodies consist of guide slots to accommodate the wedge during opening or closing of the valve. Bonnets are made either of one piece only- the yoke then being an integral part of it- or have two pieces, depending on the size of the carbon steel gate valve. This ensures the perfect alignment with the body what leads to an accurate opening and closing.
