According to the spool of the angle valve, it can be divided into spherical spool, ceramic spool, ABS (engineering plastic) spool, alloy spool, and rubber rotary spool. The advantage of the spherical spool is that the caliber is larger than the ceramic spool, which will not reduce the water pressure and flow, and is easy to operate. It can be fully opened or fully closed by rotating 90 degrees. The spool can be chrome-plated. After chrome plating, it has high hardness and wear resistance. , long service life and avoid patina. The cost of ABS engineering plastic valve core is low, and it is difficult for some small manufacturers to guarantee the production quality. The advantage of the ceramic spool is that the switch feels smooth and light, suitable for families, with a long service life and relatively high cost. The rubber rotary valve core has been eliminated now, because it is time-consuming and laborious to open and close, and the angle valve of this material is rarely used in the family at present.
