2600
Series
Swing Type
Low Pressure and Lightweight
Constructed of lightweight aluminum, the 2600 Series
Swing Check Valve has a spring-loaded, trapdoor style valve.
The valve opens when system pressure approaches 1/2 psi to
permit full flow with low pressure drop. As system pressure is
relieved, the valve closes, retaining fluids upstream.
Parker’s 2600 Series are in-line check valves designed
especially for diesel and gasoline engine fuel lines. They are
also used for externally mounted oil filters, and coolers, as
well as transmission fluid lubrication lines. With a maximum of
1/2
psi cracking pressure, these Swing Check Valves are useful
in most low pressure air, liquid, or gas systems.
