Stucture and purpose
Used at the pumpoutlet to carryoutan accurate open orclose via the pilot controlof the solenoid valve and,asa checkcontrol valve,to prevent the me-dium from back-flow.When the pump is about to stop water supply,it is slowly closed by about 90%first to prevent both W ater hammer and water shocknoise from being produced due to sudden stop of the pump and,when the pump stops completely,it isfully closed to prevent the water from back flowwith the pump so as to effectively protect it from counter movement due to the shock of the back-flow.This valve C an effectively prevent water hammerand water shock noise , be reliably sealed and long time used and stably move.The solenoid valve can use either AC220V or DC24V power.
