SPECIFICATION

1) It is reliable in sealing. The more it closes, the tighter the sealing. It is suitable for medium pressure pipes with t he nominal pressure between 16MPa and 40MPa

2) At the time of opening, the disc can separate itself from the seat promptly, thus the friction torque is low

3) The adjustment can be done for compensation if the valve seat is worn, thus prolonging the service life

4) The sealing face of the valve seat is made of PTFE, which is suitable for a temperature between -30º C and 230ºC
