aluminum bronze. Disc: Ni-plated ductile iron, Nylon coated ductile
iron, **4S. S, **6S. S, aluminum bronze and monel. Shaft: **6S.
Sand**6S. S, ***4pH. Seat: EPDM, high temperature EPDM, food grade
EPDM, NBR, abrasive resistant NBR, Viton, high temperature Viton,
Hypalon, Silicon rubber PTFE over EPDM, PTFE over NBR, Neoprene.
Bushing: Glass backed PTFE
3. Working Pressure: :
2"to6" *0bar 8"to*6" *5bar
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 *6MPa and 4MPa
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 **0º C and **0º C
