Application purpose

The Legris 7886 22 22 is an air line lockout valve built for industrial compressed-air systems. Its nickel-plated brass body and PTFE seals handle a maximum operating pressure of 145 psi and a maximum temperature of 158 Degrees F. The valve mounts in-line with 1/2 in NPT male inlet and 1/2 in NPT female outlet connections.

Who should use it and who should not

Maintenance teams needing a compact shut-off for pneumatic lines will find the 2 1/4 in height and 1 1/8 in width easy to fit in tight machine envelopes. The single-inlet, single-outlet design suits simple branch isolation but cannot serve circuits requiring multiple outlets or integrated filtration. Buyers needing higher pressure ratings or different port sizes must select another series.

Deciding specification

The critical figure is the 145 psi maximum operating pressure combined with the 1/2 in NPT port size; both must match the system design data exactly. The valve also meets PED, REACH and ROHS standards and carries a California Proposition 65 warning for listed chemicals. Verify these parameters against your installation requirements before ordering.

Questions about this item

What does the 145 psi rating mean when the valve is installed in an air line?

It indicates the maximum operating pressure the valve can handle continuously without leaking or failing.

How does the 1/2 in NPT connection affect compatibility with existing fittings?

The male inlet and female outlet both use 1/2 inch NPT threads, so they mate directly with standard 1/2 inch NPT pipe or hose fittings.

What clearance is needed to mount the valve given its overall height and width?

The valve measures 2 1/4 inches tall by 1 1/8 inches wide, so allow at least that much space in the mounting area.
