Use and design features:1. Mainly used for water system, adjust and closure equipment used to do;

2.3 "24 "rubber seat directly vulcanization to the body, can avoid the seat migration and medium pollution; 30 "72 "seat with press fixed in body, can achieve on-line maintenance, replacement;

3.30 "72 "eccentric structure, equipped with overflow valve disc way, can obtain higher intensity, light weight, the more more port area, higher Cv value

4. All specifications disc seal face for stainless steel, can reduce the valve shut up torque and longer service life.

5. Through the disc sold connection design, and greatly reduce the vibration and produce components loose because of possibility;

6. V type or U sealing ring from seal, prolong the service life of the valve;

7. According to AWWA C504 valve for switch life test, in the life of the valve, within the scope of reliable performance;

8. Design pressure, completely sealed, leakage is zero
