INTEGRAL MONEL SEAT IN BODY WITH ELASTOMER SEAL  RING IN DISC
An integral seat in body precludes the possibility of leakage from beneath a separate seat ring besides, eliminating components like ‘O’ ring for the seat, screws / nuts / washer and the seat ring itself. Monel, a cupro – nickel alloy, nickel in excess of 57%, is highly resistant to any form of corrosion and therefore the Monel integral seat is good for life and is maintenance free.
