LAFFERTY - USA
Chemical Check Valve, Stainless Steel, Viton
Item no. 07 491324-V
Genuine Lafferty chemical check valve for foamers, sprayers and mixing stations. A check valve lets chemical flow one way only, so the pick up line stays primed between uses and water cannot push back into the chemical container. A sticking or worn check valve is a common cause of a foamer that loses its draw or gives uneven dilution.
For acids and petroleum based solvents.
