Zhejiang Jigong Valve Co., Ltd. is one of the most reliable manufacturers and suppliers of l-port valve ball in China. If you're going to wholesale cheap l-port valve ball made in China, welcome to get pricelist from our factory. All customized products are with high quality and low price.
Product Introduction
The L-port valve core is a special fluid control component designed for **90° right-angle reversing only**, with a built-in single right-angle flow channel that only realizes two-way pipeline switching and does not involve medium mixing or shunting. The whole flow channel is polished and formed, with no redundant cavities, which ensures the medium only flows in a fixed right-angle path. It is specially used for simple pipeline reversing and on-off control in conventional industrial systems, with stable action and no medium cross-contamination hidden danger.

Common Questions
Can this L-port core realize medium mixing function?
No, it only has 90° right-angle reversing function, no medium mixing or three-way shunting function.
What is the switching angle of the L-port valve core?
Standard 90° rotation switching, matching the action stroke of conventional ball valve actuators.
Will there be medium cross-contamination during switching?
No, the single flow channel design has no residual cavity, and medium will not mix or remain during reversing.
Is it suitable for frequent switching operation?
Yes, compact structure and low friction make it ideal for frequent cyclic reversing control.
What kind of valve body is this core suitable for?
Only suitable for three-way ball valves that need simple reversing, not for multi-channel mixed transmission valves.
