Features & Benefits
- 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/PH 17-4 materials.
- ISO 5211 mounting pad with square shaft 2"-12". Key Type connection 14"-24" 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 304/316), Fire-Safe Seat. 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 gasket sealing surface to prevent external leakage.
- Heavy duty handle and 10-position notch plates allow for positioning the valve disc to precise angle stops.
