W45 / W45HMP Series - Spring Disc Check Valves

W45 Series

• In the absence of forward flow pressure, the electropolished spring returns the disc and holds it closed against the seat. Back flow pressure also pushes the disc into the closed position.
• Two available seal options: O-Ring or Tri-Ring; in the disc OD provides tight closure while metal-to-metal contact between the disc and seat allows for long-lasting, durable operation.
• Machined from 316L stainless steel bar with all polished surfaces < 32 Ra, the W45 check valve has smooth internal surfaces for superior cleaning.
• When free-draining is required, the W45 must be vertically mounted.
