Perfect adherence between the rubber joint lodged in the periphery of the disc and the seat of the
stainless steel body provides total watertightness.
Long lasting closing joint. During manouvers there is no drag of the seal against the body, making
contact with metal parts only in the last phase of closing.
Closing action is faster.
Considerable reduction of torque.
EPDM ring can be replaced without dismounting the valve.
“O” rings can be replaced without dismounting the valve. Installation in horizontal position.
We may include hydraulic dampers for a slower closing.
