For Ratings at the following temperatures, multiply the 150° rating by the multiplier of the desired temperature.
No. 9A Base-Ray
®
Ratings – Steam and Hot Water (2000 LBS/HR Flow Rate **)
Ratings based on active length. Active length same as total
length.
9A Base-Ray Water Content - 2.5 lbs. or .3 gal. per linear ft.
**The Hot Water Ratings at 2000 lb. Flow Rate are limited to installations where the
water ow rate through the Base-Ray is greater than 2000 lbs. per hour (four gallons
per minute). Where the water ow rate through the Base-Ray is not know, the rating
at the standard ow rate of 500 lbs. per hour mst be used.
*Add ½" to length for each bushing. Add 5" to length for each valve enclosure.
***Based on ¾" pipe connections.
