Ratings based on active length. Active length same as
total length.
**The Hot Water Ratings at 500 lb. Flow Rate are based on a standard water ow
rate of 500 lbs. per hour (one gallon per minute) through the Base-Ray. These ratings
should be used for all installations except as noted under 2000 Lb. Flow Rate.
*Add ½" to length for each bushing. Add 5" to length for each valve enclosure.
***Based on ¾" pipe connections.
For Ratings at the following temperatures, multiply the 150° rating by the multiplier of the desired temperature.
