Aleum (Fivalco) Grooved Swing Check Valve 300psi
VGSCV-(size OD)
- Model #DGC
- Size Range: DN50 to DN300
- Max. Working Pressure: 300psi (2100kPa)
- This Check Valve is a Compact, Cost Effective Valve Offering Low Pressure-Drop, Non-Slam Performance.
- The Assembly is Lighter, and Installation is Faster, and Less Costly Than Flanged Valve Assemblies.
- DN15 Tapping Points Provide Above and Below the Clapper For Drain Down or Pressure Switch or Gauge.
- In Full Operation, Swing Clapper is Held Tightly Against the Valve Body, Out of the Flow Stream, to Provide Maximum Flow Area and Prevention of Clapper Flutter. The Spring Assisted Clapper Design Produces Quick, Non-Slam Closure Before Flow Reversal Can Occur While Meeting Requirements For an Anti-Water Hammer Valve Rating.
- Each Valve is Hydrostatically Tested For Leak Tightness to 3500kPa. The Clapper-Seat Design Permits Leak Free of Back Pressure Sealing in Service Pressure Conditions.
- UL Listed
- FM Approved
