Emergency shut-off valve for copper tube systems

This lead-free brass ball valve provides emergency shut-off for 1-1/2 in copper tube installations. It is rated for a maximum pressure of 250 psi and suits glycol and water systems. The valve includes 518 gasket sealant for the connection.

Brass body handles pressure

The brass construction manages the 250 psi rating using a quarter-turn ball mechanism. No external power or actuators are required for normal operation. Thermal and acoustic characteristics follow typical brass valve behaviour in plumbing circuits.

Sweat connection with supplied sealant simplifies

The sweat-end design requires soldering to copper tube, and the included 518 gasket sealant assists the joint. Lead-free brass meets potable-water regulations. The valve serves as a single-point shut-off; systems needing isolation at multiple points will require additional valves.

Questions about this item

How do I sweat the 1-1/2 in brass body onto copper tube without leaks?

Clean the tube end and valve socket thoroughly, apply flux evenly, heat the joint uniformly with a torch, then feed lead-free solder until it flows around the full circumference; the included 518 gasket sealant is for threaded connections, not the sweat joint.

Which component will need replacement first in a glycol system?

The PTFE seats and stem seals inside the ball valve will wear before the brass body; inspect them during routine maintenance and replace the seat kit if seepage appears at the stem or ports.

At what pressure does the 250 psi rating become the limiting factor during sustained operation?

The 250 psi maximum working pressure is the first hard limit; sustained pressure spikes above this value can deform the ball or seats, so install a relief valve set below 250 psi for continuous duty.
