FEATURES

● Top plate drilled to fit ISO 5211 bolt circle dimensions. All handles, gear operators and Deltorq® actuators are designed to mount directly to DelVal® valves.

● Bi-directional ‘U’ cup stem seal.

● One-piece disc/stem in high strength design. Available in stainless steel and other alloy steel (thin profile, with hand polished edge and hubs).

● Precision machined radius on the upper and lower disc hubs is pressed against upper and lower seat sealing faces for achieving primary sealing between disc and stem.

● Heavy duty acetal bushing absorbs the forces acting on the stem/disc assembly due to line pressure.

● Heavy-duty, two-piece body with extended neck for 2” piping insulation. Two coats of hard, zinc-rich epoxy for excellent corrosion resistance is optional.

● Two flange locating holes for sizes up to 12” for easy alignment of valve during installation. They meet ANSI#125/150 or other international drilling standards.

● Unique heavy-duty seat design virtually eliminates any seat movement during the seating and unseating of the disc. Available in PTFE lined EPDM materials.
