Good To Know

Q: Can this swing check valve be installed vertically? A: This model is specifically designed for horizontal lines, as gravity assists the internal swing flap in closing properly.

Q: Is this valve suitable for chemical or fuel lines? A: It is primarily designed for water and non-corrosive fluids; check material compatibility before using with fuels or acids.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
