ADVANTAGES Provides Flow Control Can Work At High Temperatures Since the stroke distance is short, the number of opening and closing rounds is low. The seat does not damage the seat surface in contact with the seat. Metal-to-metal sealing is achieved very well. DISADVANTAGES As seen in the figure, as the fluid changes direction inside the valve pressure losses are high. Fluid accumulation occurs on the damper depending on the fluid type, which causes the stroke length to be shortened. It only allows one-way flow. (excluding gate valves)
