▪ Tight shut-off design.

▪ One – piece body materials are either cast steel or
stainless steel for excellent corrosion resistance.

▪ High strength one-piece stem in A564 Gr.630 materials.

▪ISO 5211 mounting pad with square shaft permits
direct mount actuation for both Manual (Lever & gear),
pneumatic and electric actuators.

▪ Double off-set configuration with conical angled disc design.
Maximize flow and minimize resistance providing high Cv.

▪ Seat available in either Soft (PTFE / RTFE) NBR, EPDM, VITON or
Metal (A240 Tp 316 / 304).
Both soft seats and Metal seats are interchangeable.

▪ Gland Flange preventing uneven load distribution against packing.

▪ Internal travel stop design to prevent over travel of the disc.
Minimizing possible seat damage.


▪ Retainer ring surface finish is 125 to 200 AARH and is compatible
with both standard gasket and spiral wound gasket designs. Outside
diameter is recessed within a gasket sealing surface to prevent external
leakage.


▪ The heavy-duty handle and 10 position notch plates allow for
positioning the valve disc to precise angle stops.
