The present invention relates to a catheter valve for use with a catheter. The catheter valve comprises an inlet nozzle at a front end of the valve and an outlet nozzle at a rear end of the valve. The valve comprises a longitudinal stem encapsulated within a middle section of the valve which extends in between the front end and the rear end of the valve. The longitudinal stem is divided into a front end and a rear end by a rib and an O-ring is inserted into the front end of the stem; and a resilient means is inserted into the rear end of the stem; the front end of the longitudinal stem further comprises sectional longitudinal grooves which cuts across the longitudinal and cylindrical stem extending from a head end of the front end of the stem up till the rib of the stem and the head end is curved inwardly in between each sectional longitudinal groove; and the rear end of the longitudinal stem further comprises sectional longitudinal grooves which cuts across the longitudinal and cylindrical stem in a triangular form extending from a head end of the rear end of the stem up till a bottom interface of the rib.
