116-31 (Globe) / 1116-31 (Angle)
PRESSURE SUSTAINING / SOLENOID ON-OFF
Installed in a mainline it prevents upstream pressure from dropping
below a preset minimum. Solenoid override of the sustaining function
allows for electrical on-off operation.
NOTE:
Adjustment range:
Standard: 20-200 psig
Optional: 0-30 psig,100-300 psig
Solenoid max. W.P.:
At time of order, advise factory actual system working pressure for
correct solenoid selection. (consult factory if over 150 psig.)
Enclosure: NEMA 1, 2, 3, 3S, 4, 4X
Optional: Explosion proof
NEMA 3, 3S, 4, 4X, 6, 6P, 7, 9
Specify energized to open or energized to close main valve.
QUICK SIZING: Valve size same size as line.
Points to consider:
– Refer to Engineering Data - Flow Capacity Chart
Pressure drop at required flow
Refer to Engineering Data - Pressure Drop Chart
PRESSURE RELIEF / SUSTAINING
116 (Globe) / 1116 (Angle)
PRESSURE RELIEF / SUSTAINING
Installed on a by-pass line, mainline pressure is accurately controlled
by relief of excess pressure. Installed in a mainline it prevents
upstream pressure from dropping below a preset minimum.
NOTE:
Adjustment range:
Standard: 20-200 psig
Optional:
0-30 psig
100-300 psig
Additional relief/sustaining
functions:

116 RELIEF
QUICK SIZING: Valve size one or two sizes smaller than main line.
Points to consider:
– Refer to Engineering Data - Flow Capacity Chart.
If valve size required is smaller than line size, consider ACV 6116.
Consult Watts ACV representative/factory.
