CHECK VALVES

Globe Style Silent Check Valve

Eliminate water hammer with a check valve that operates smoothly and silently itself. The Metraflex #900 Series features a center guided single disc and stainless to stainless seating with special stainless steel spring control to insure positive, noiseless opening and closing.

  • Made in fourteen standard sizes: 2-1/2" through 30"
  • Work in any position
  • Activated at 1/4 to 1/2 psi
  • Constructed of cast iron body with stainless steel trim
  • Compacted into shortest possible face-to-face dimensions
  • Designed with larger-than-pipe-size flow area for low pressure loss with maximum efficiency

Intended for liquid service only.

Note #1: 2-1/2" through 10" valves mate to wafer-style butterfly valves without use of spool pieces or other adapters.
