Detail

This product is a 90° rotary ball valve with excellent sealing performance, large flow capacity, low flow resistance coefficient, and features such as simple structure, easy maintenance, and long service life.

The valve body channel and connecting pipe diameter are equal and form a single diameter, allowing the medium to flow through with minimal loss. Coupled with high-performance actuator institutions such as JL and JLQ, the product is typically used in applications with strict sealing requirements. In addition to controlling gas, liquid, and steam media, it is also suitable for controlling sewage and media containing fibrous impurities.

It is widely used in various fields such as petroleum, chemical industry, metallurgy, light industry, papermaking, power generation, and refrigeration.
