1. The unique design of three-way eccentricity enables frictionless transmission between the sealing surfaces and prolongs the service life of the valve;
2. Elastic seal is produced by torque;
3. The ingenious wedge-shaped design enables the valve to have an automatic sealing function of tighter and tighter closure, with compensatory and zero leakage between the sealing surfaces;
4. Small size, light weight, light operation and easy installation;
5. Pneumatic and electric devices can be configured according to user requirements to meet the needs of remote control and program control;
6. The material of the replacement parts can be applied to various media, and can be lined with anti-corrosion (lining with F46, GXPP, PO, etc.);
7. Continuous structure diversification: wafer, flange, butt welding;
