Vatac Non Slam Check valves are specifically designed for fast-reversing systems where backflow is a constant concern. In such critical service applications, Vatac Non-Slam or Nozzle Check Valves offer the following benefits. Axial Flow Non slam check valves or Nozzle Check Valves from Vatac are designed and manufactured strictly to updated International Standards of ASME B16.34 or Equivalent
» Minimizes the damaging effects of water hammer in fluid systems
» Removal of chatter associated with conventional valves in reciprocating compressor service
» Protects rotating equipment from damage due to flow reversal
» Minimizes pressure loss in piping systems
» Provides quick dynamic response reducing reverse velocity
Main Features & Advantages
» Few moving parts minimizing wear.
» Axial movement of disc resulting in low pressure drop.
» Short stroke of spring-assisted disc providing valve closure quick response
Vatac Non Slam Check valves deliver an effective dynamic response under various flow deceleration conditions, this unique design features result in superior performance, fast response and lower pressure loss in piping systems.
