VCV – Non-Slam Venturi Check Valve

The Non-Slam Venturi check valve is primarily used to protect pumps and compressors from damage caused by back-flow.

The Europa Non-Slam Venturi Check Valve is designed for severe service applications where fast reverse flow exists and conventional check valves are unsuitable for the existing flow conditions. 

Non-Slam Venturi Check Valve Benefits

Installation of the Non-Slam Venturi Check Valve’s offer the systems engineer the opportunity to:

  • Protect equipment, particularly compressors from expensive damage caused by reverse flow
  • Reduce downtime and loss of production due to failure or frequent replacement of unsuitable valves
  • Make energy savings as a result of a low-pressure drop
  • Eliminate chatter and reduce the possibility of sudden valve failure in reciprocating compressor applications
  • Reduce or eliminate water hammer
  • Lower maintenance costs; few moving parts
  • Reduce reverse velocity using the fast dynamic response of the Europa VCV non slam check valve
  • Smaller footprint than conventional check valves with associated dampers/levers
  • Flexibility to cope with variable flow conditions
  • API 6D end to end dimension permits interchangeability with most conventional swing check valves without expensive piping modification

Venturi Non-Slam Check Valve Applications

The Non-Slam Venturi Check Valve is primarily used to protect pumps and compressors from the damage caused by back-flow. Offering a combination of the fastest response and lowest pressure drop of any check valve type. Therefore it is the pinnacle of the check valve family.

Above all, the Europa Non Slam Venturi Check Valve is designed for severe service applications where fast reverse flow exists and conventional check valves are unsuitable for the existing flow conditions.

The Europa Non Slam Check Valves are specifically sized and designed for the flow condition of the specific location. In addition the valves are installed to enable optimum performance. Furthermore, it should be noted that there is no such thing as an off-the-shelf Non Slam Check valve. Customers should be wary of such products as this would raise major questions. For instance, given that sizing is so critical for this product to achieve the optimum performance with low pressure drops and long service life. The Europa Non Slam Venturi Check valve is designed for a long service life. Under typical operating conditions and installation locations, there should be little or no maintenance required.

The Europa Non-Slam Check valve can be manufactured for a wide range of applications and temperatures ranging from full cryogenic -196ºC up to valve operating over 500ºC. Covering a vast range of service including Natural Gas, LNG, Steam, Water, Sea Water, Desalination, Petro Chemical, Hydrogen, etc. In conclusion, as with all Europa Non-Slam Check valves are engineered in-house in the United Kingdom this allows for large flexibility of special application and configuration of valves we are offering.
