  • FEATURES & BENEFITS
  • TECHNICAL
  • DOCUMENTATION
  • OPTIONS
  • APPROVALS
  • APPLICATIONS
  • Wafer and lug
  • ASME Class 150, 300, 600
  • Tight shut-off design
  • One-piece body materials are either Cast Steel or Stainless Steel for excellent corrosion resistance.
  • High strength one-piece 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 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.
  • Heavy duty handle and 10 position notch plates allow for positioning the valve disc to precise angle stops.
