Spring Loaded Y Check Valves

Spring Loaded Y Check Valves These Y check valves are spring loaded to creat a seal even in the absence of back pressure. These are often used to reduce water hammer when pumps are started in an empty, open line. These are hand adjustible for opening at pressures from 2 to 15 PSI. PVC construction with FPM or EPDM seals, these Y check valves work in any orientation. True union connections are available.
