By utilizing the fluid characteristics, the suspended particles with larger proportion and diameter will not enter the control system, ensuring the smooth circulation of the system and ensuring the safe and reliable operation of the valve. The system operates smoothly, has high strength and long service life. It is suitable for pipelines with diameter below DN600 mm.
