Rating & Purpose
Serve as by-pass valves to control full pump
capacity of 36,000 gpm at 636* F, and 2,125 psia,
or to control normal 23,500 gpm flow of the
36,000 gpm while balance of 12,500 gpm is con-
trolled via valves W4 thru the water coolers;
characteristics to be such that each valve can
control down to 50% of normal flow of 5,880 gpm
per valve; pressure drop per valve while passing
5,880 gpm at 4860 F to be no greater than about
10 to 12 psi at about a 530 valve open position,
with valve blade and shaft design to sustain up to
125 psi maximum differential while controlling
at smaller flows approaching a 00 open blade
Serve as by-pass around valves W2 to provide a
water flow circuit by which heated water may be
circulated to keep pumps at near operating tem-
peratures during standby condition.
Serves as cooling water pump suction shut-off
valve; maximum flow rate about 1,200 gpm at
70*F; maximum pressure drop about 4 psi.
Serves to check reverse flow thru pump; maxi-
mum flow about 1,200 gpm at 70*F.
Serves to by-pass pump flow back to suction
side of pump if pressure builds up to predeter-
mined values depending on control demands of
Serve to control shell-side water flow to water
coolers #1, #2, and #3, respectively; maximum
normal flow per valve about 480 gpm at 70*F;
characteristics per valve to permit handling
of 50% of normal flow.
Serve to release steam to atmospheric exhaust
from water coolers while maintaining preset
saturated back pressures corresponding to
those ranging from 320*F to 486*F shell-side
temperatures, and discharging up to the steam
volume equivalent of 400 gpm of 70*F water per
Sizes shown are applicable to double-seated
valves; however, butterfly, plug , or other
throttling-type valves in required number and
sizes may be provided for each cooler to meet
