NPFC - MIL-V-18436 - VALVES, CHECK: BRONZE, CAST-IRON, AND STEEL BODY Organization: NPFC
Date: 1987-11-06
Description: Nonmetallic disks, when rated for media temperatures involved, result in quieter operation, will seat even when the media contains small particulate matter, and provide tighter closure at lower pressures, especially for air and gas service. Tilting disk check valves and spring-loaded check valves are characterized by rapid closure action which tends to minimize flow reversal and resultant hydraulic hammer.
