CHECKFLO SERIES DGB NOZZLE CHECK VALVES
CheckFlo Series DGB Nozzle Check Valves are a Central Shaft Design that prevent Water Hammer and reverse flow and insure long and trouble free operation.
Each check valve in our range balances the capital cost with ease of installation and performance to provide an optimum solution to the end user.
CheckFlo Check Valves were designed utilising the latest in Finite Element Analysis (FEA) and Computational Fluid Dynamics (CFD) software. Each validated design was heavily prototyped and refined followed by independent flow and hydrostatic testing. This has resulted in a light weight moving assembly with excellent flow and dynamic characteristics for each design type. The result is that CheckFlo Check Valves provides the best combination of flow efficiency and excellent dynamic response in comparison to any conventional check valve design.
CheckFlo Series DGB Nozzle Check Valves
Size Range:
DN 50 – DN 1200 – Larger valves available on request
Pressure Range:
PN 10 – PN 64
Features
- Non slam closure
- Low pressure loss
- Maintenance free
- Metal to Metal or Soft Seal options
- Highly customisable
- Choice of Face to Face length
The Venturi design and streamlined flow path allows for high pressure recovery and minimising pressure drop across the valve. This efficient design combined with the highly responsive non slam operation makes it ideal for critical pump applications.
Type DGB-SF:
This is a short face to face Central Shaft design available in both wafer and flanged options, this design is perfect for conditions where surge protection is imperative and where space and weight is at a premium.
Type DGB-LF This is a long face to face Central Shaft design. Its optimum designed aerodynamic flow path results in very low pressure losses. It is also available in customised face to face lengths to suit the clients flow and installation needs.
