There are a number of benefits and advantages to using non slam check valves:

• protect pumps and compressor equipment from damage caused by backflow / reverse flow
• reduce down time and loss of production due to failure of unsuitable valves
• low pressure drop increases energy savings
• check valves are very effective in preventing water hammer
• eliminate chatter and reduce the possibility of sudden valve failure
• lower maintenance costs; fewer moving parts
• smaller footprint than conventional check valves
• flexibility to cope with variable flow conditions
• interchangeability with most conventional swing check valves without expensive piping modification
