Entech supplies several types of nozzle checkvalves originally developed in 1905 for use with the company's pump products. Designed to provide long service life and nonslam performance, recent flowpath enhancements have provided these checkvalves an extremely low pressure drop. Nozzle checkvalves can be mounted in any position, and are suitable for liquid and gas service. Size ranges from 2 inch to 96 inch in ANSI 125 through API 15,000 in any commercially available material.
