Features & Benefits

  1. Butterfly valves come standard with an integrally cast actuator mounting pad; machined and drilled in accordance with ISO-5211 and MSS SP-101.
  2. Our butterfly valves utilize stainless steel shafts to resist corrosion and ensure long valve, bearing, and packing life. 316SS is the standard shaft material for CL 150B, while 630SS (17-4) stainless steel is utilized for CL 250B.
  3. Our fully rubber-lined bodies for 3”-24” valves eliminates the need for inner body coating and effectively prevent abrasion from particulate in the media.
  4. Our disc-to-shaft pinning connections are built in accordance with AWWA C504. We utilize a 630SS (17-4) pin that is held in place with stainless steel nuts, creating a strong and reliable connection. This ensures that our customers will get many years of dependable, backlash-free service from their valve.
  5. PTFE-lined fiberglass bearings are designed to provide low friction and long life, reducing the required maintenance and requiring no lubrication.
