Product Details
- The disc seating surface is precision machined and polished for low operating torque and longer seating life
- The primary stem seal is achieved between the disc and seat. Secondary seals are incorporated into both the upper and lower stem to backup the primary stem seal
- Three radius seating profile reduces operating torque while providing bubble-tight and positive shut-off
- Uniform and smooth surface finish. Streamlined for maximum flow and minimum seat wear
- Stem material is heat treated with 400 series stainless steel material that provides additional tensile strength
- The 10 position lever handle is lockable to provide tamper-proof flow control. Locking mechanism accommodates standard padlocks
- Secured and precision connection on stem-disc joint provides maximum strength of disc/stem connection and minimum unwanted free travel
- Integral flange seals molded into the edge of the seat require no flange gaskets
- The rigid backing ring eliminates high torque and premature failure caused by elastomer distortion found in butterfly valves with non-rigid seat designs
- Non-collapsible phenolic backed cartridge seat provides superior sealing integrity
