1.5 Inch Check Valve

Description

A 1.5 inch check valve is a mechanical device that allows liquids and gases to flow in only one direction, preventing the flow from being reversed. They are classified as one-way valves, which means they have two openings in the body, one for fluid to enter and one for fluid to leave.
