Features & Benefits

  1. RECESSED GLAND: Our recessed gland packing eliminates the requirement for mounting kit and reduces overall package height. A rocker design gland flange and packing gland are utilized to ensure even compression of the packing.
  2. EXTENDED NECK: Bonnet to flange clearance is a minimum of 2” allowing for piping insulation on all sizes of valves.
  3. BODY: High quality one-piece casting provides consistent uniformity. Body is available in Wafer or Lug style. Body materials include carbon steel (WCB) and stainless steel (CF8M).
  4. INTEGRALLY CAST DISC POSITION STOP: Machined position stop in the body locates the disc in the seat to achieve maximum sealing and seat life.
  5. SEAT RETAINER PLATE: Constructed of the same material as the body, our seat retainer plate assures proper sealing and allows for full rated bi-directional dead end service.
  6. SHAFT: Our 17-4PH Stainless Steel shaft provides maximum strength and stability for high pressure applications.
  7. BONNET: Allows for direct mounting of all types of actuation. Standard drilling conforms to ISO 5211.
  8. PACKING: Multi-layered, V-type PTFE packing allows for even compression against shaft and body, providing a positive seal even under high pressure / high cycle applications.
  9. BLOWOUT PROOF STEM: Our shaft retention system is designed per API 609 standards.
  10. SEATS: High Performance Butterfly Valves feature an innovative free-floating, pressure-assisted, solid seat design that ensures a positive seal under both low and high pressure requirements. Unlike traditional valves, our seat does not rely on secondary components like O-rings or springs, resulting in a longer service life with minimal maintenance.
  11. DISC TAPER PINS: Pins are offset from the center of the stem which places them in compression and gives them a yield point greater than the stem itself.
  12. DISC: Standard construction is 316 stainless steel. Designed to have minimum deflection and movement under pressure, which reduces torque and improves cycle life. Double offset discs produce a camming motion, allowing it to release from the seat within the first few degrees of opening and reducing wear.
  13. BEARINGS: Woven fabric steel backed bearings provide excellent load-bearing capabilities, are self lubricating to provide improved wear life, and are tolerant to harsh high pressure applications.
