Questions about this item

What does the 600 psi CWP rating on this Jomar 102-303 valve mean for water, oil or gas lines?

It certifies a maximum cold working pressure of 600 psi for non-shock liquid or gas service; steam service is not rated.

What pipe threads are required to connect the 1/2 inch FNPT ends on this brass ball valve?

Each port accepts a 1/2 inch male NPT thread; apply PTFE tape or pipe dope on the male threads only.

How is the blowout-proof stem on this 102-303 valve installed, and what common error should be avoided?

The stem is assembled from inside the body and retained by the packing nut; do not remove the packing nut while the line is under pressure.
