PVDF Check Valves
from Asahi/America, Inc.
Swing check valves have the option to install an external spring assist assembly. This spring is made from 316SS and is mounted external to the valve. When fluid pressure starts to drop, the spring retracts the swing arm and brings the disc back into the seat position. This effectively reduces the... [See More]
