NOZZLE AXIAL & DUAL PLATE CHECK VALVES :
A wide range of Check “Non Slam” Valves are included in INVALVES manufacturing range.
Nozzle “Axial” Check Valves are the best and recommended solution for high pressure critical return flow applications,
(such as compressor and pumping systems, where return flow would cause damage to the equipment by driving them in reverse), and in all that systems where Low Pressure Loss, Quick Closure, Excellent Dynamic Behavior & Severe Duty are mandatory requirements.

Nozzle “Axial” Check Valves are manufactured in sizes up to 24” class 1500# & sizes up to 48” class 600#, with Flanged, Butt Welding & Hub Ended connections.

Dual Plate Check Valves, which are a recommended solution for non-return application in those systems involving rotating equipment, have significant benefits if compared to conventional swing check valves
