Body
GGG40 is standard - 3 layer coating EPOXY/EPOXY/PUR, 160 µ.
Types: wafer, lug and double flange.
Multi-standard alignment holes suitable for mounting flanges:
DN40 - DN300 wafer type:
EN1092 PN10, PN16 - ANSI150 -
BS10 TABLE D, TABLE E, JIS 10K, 16K.
DN350 - DN600 wafer type:
EN1092 PN10, PN16 - ANSI150 - BS10 TABLE D.
DN40 - DN150 lug type:
EN1092 PN10, PN16 or ANSI 150.
DN200 - DN600 lug type:
EN1092 PN10, PN 16 or ANSI150.
Mounting bolts lug: PN = Metric and ANSI = UNC
ISO 5211 top flange according to valve torque.
Relief track on the ISO top mounting flange.
Seat
A unique dynamic wave line rubber seat provides a highly efficient seal.
Reduced torque.
Extended sealing life span.
Making automation a very price competitive.
On the wafer type the seat is vulcanized to a phenolic back-up ring - a re-
placeable construction - on the lug type the seat is vulcanized onto the body.
Simple seat replacement.
100% tightness at full differential pressure (PN16 = 16 bar from DN40 -
DN150, PN10 = 10 bar from DN200 - DN600).
Ideal for full vacuum applications.
Trouble-free mounting between flanges.
Disc
Disc with two-piece shaft construction which enhances the Cv value of the
valve and reduces turbulence.
The shape and finishing of the edge of the disc, provides the lowest possible
operating torque with bubble-tight shut off, even at maximum operating pres-
sure, thus extending the life span of the valve.
