Questions about this item

What size flanged pipe connection must my existing plumbing have to install this 2 in valve?

The valve uses a 2 in flanged connection, so the mating pipe or flange must also be 2 in to bolt directly to it.

Will the PVC body and FPM diaphragm handle the same 150 psi pressure rating as my older metal trap rated for 150 psi?

Yes, this valve is rated for 150 psi maximum pressure, matching that rating, and its PVC body with FPM diaphragm and seals is designed for that working pressure.

After installation, how can I confirm the valve is operating within its 40 to 140 Degrees F fluid temperature range?

Measure the fluid temperature at the valve inlet; if it reads between 40 and 140 Degrees F the valve is within its specified operating range.
