V type regulating valve as the ball core with V type structure, with shear effect on the valve seat. Therefore suitable suspension medium in papermaking, chemical, metallurgical and other industrial enterprises contains small particles and fiber to control the process parameters, automatic control fluid is especially suitable for pulping, paper production process of paper pulp, white water, black liquor, white liquor and other suspended particles concentration, turbidity and slurry fluid medium
Product features:
■ with elastic load pressure auxiliary seal seat to ensure the seat and the ball core from efforts to eventually close contact
■ valve with integral type structure, there is no potential leakage may
■ with equal percentage characteristics, control process control range is very wide and stable, and can be widely used in a variety of processes
■ stem and ball core adopts involute spline connection, when the tooth profile is subjected to load, radial force on the teeth can play the role of auto-centering, strength and each tooth force uniform so high, long life
