2. Small open height. The valve has the following advantages: 1. In the process of opening and closing tightly closed surface friction is smaller than gate valves, wear-resisting. By the time the valve in the pipeline mainly used as truncation. Q: as of valve's unique place and classification of answer: the valve is closed ( The disc) Along the core line movement of the valve seat. 3. Usually only a tightly closed surface, making craft is good, easy to maintenance. By the valve of the category is numerous, according to the position of the valve stem turnbuckle can be divided into: a, turnbuckle stem by valve by valve stem of the turnbuckle outside the body. By the valve using a more widespread, but because of the opening and closing torque is larger, the structure length is longer, common nominal diameter all limit below DN 200 mm or less. This structure is used for small diameter and temperature is not high. Its strengths is stem from the medium erosion, easy lubricating oil, the structure that suitable and more widespread use. 。 Marine valve according to the channel direction of the valve, can divide again; Straight through the valve, Angle type of valve and three general formula by the valve, the latter two by the end of Industrial Valves generally do change medium flow and distribution of media use. The structure of valve stem turnbuckle, direct contact with the medium susceptible to erosion, and there is no way to lubricating oil. By the end of valve fluid resistance loss is bigger. So the limit by the valve more extensive use. Second, under the turnbuckle stem by valve by valve stem threads in the valve body. Notes to the order: The national standard) A, A: B: product name, model, nominal size medium and temperature, pressure range C: whether there is attachment, delivery time, and special requirements so that we can correct selection for you.
