Because of its highadjusting precision, small cavitation, noise and vibration, good energydissipation effect, ideal flow-open curve, easy to realize automatic control,the valve has been widely used in many large water conveyance project
Depending on the power operation, the dailyaverage power consumption is usually about a few degrees. Generally, the upperand lower water level (water pressure) is monitored by sensors. The controlsystem relies on water level or water pressure to control the actuator, andthen controls the valve opening degree to accurately control the flow throughthe valve. The theoretical error will not exceed 5% of the design flow. Thesite does not require complex calibration of the equipment. Can maintainconstant flow accurately
Piston valve is based on the piston insidethe valve body to move back and forth, to control the opening of the valve, soas to effectively control the flow, pressure and so on. The flow channel in thepiston valve is axial symmetry. When the valve is opened, the flow of watergathers at the outlet, the flow of fluid does not produce turbulence, andcavitation is effectively eliminated. Thus avoiding the transfer of upstreampressure.
