Valve opening and closing pieces are cylindrical piston design, when the valve is opened, the cylindrical piston will not be affected by the fluid blind force, the valve operating torque will be greatly reduced, the torque value of only conventional gate valve or butterfly valve One-third to one-fifth of the torque value. Piston opening and closing parts in the crank-slider mechanism to do linear motion, the valve flow coefficient and the valve opening between the approximate function of a linear (linear). Stainless steel piston in the copper alloy guide rails to do the axis of movement, the two materials with the flow so that sediment will not accumulate between the further reduce the operating torque of the valve.

The fan blade is a fluid-directing element in the valve with an alignment guide vane. As the fluid flows through the valve, the fluid upstream is forced to split into a small stream of small bunches of water that flows out in a spiral pattern and is directed to the center of the line, avoiding cavitation and other effects on the line damage. Because the cavitation bubbles are extremely unstable and will evaporate, the pipeline center is broken away from the surface of the pipe wall, so that the pipeline damage caused by cavitation can be avoided. When the water flow is cut off or blocked, the water flow through a small area of ​​the passage, the flow rate will increase, and the pressure will be reduced, so that when the water pressure drops below the evaporating water pressure, the bubbles will evaporate.

The squirrel-cage cylinder is a perforated part that extends from the piston. The size of the squirrel-cage can be designed to suit different conditions. When flowing through the squirrel cage, the water is throttled into many high-velocity fluids that flow through the squirrel cage toward the center of the runner and collide with each other. Because cavitation is controlled at the center of the runner, its energy will cancel each other out or gradually attenuate through the center of the line, thus leaving no vibration or cavitation damage to the duct. Fluid velocity energy (kinetic energy) through the piston valve is transformed into pressure energy, the pressure energy in a straight line can destroy the cavitation bubble cavitation, and thus protect the fluid damage to the pipeline.
