SURGE RELIEF / CHECK
116-52 (Globe) / 1116-52 (Angle)
SURGE ANTICIPATOR RELIEF / REMOTE SENSE
Used in pumping systems to protect equipment from damaging pres-
sure surges or waves caused by rapid changes of flow within the
pipeline. The 116-52 responds by opening at a preset low pressure
setting, allowing for quick relief of the returning high pressure wave.
The valve remains open as the integral accumulator is charged and
then closes. This prevents possible excess system drainage should
pressure not return to/above the low pressure setting. It is also
equipped with a high pressure control pilot which allows for high
pressure relief service.
NOTE:
Adjustment range:
Low pressure: standard 20-200 psig, optional 0-30 psig.
High pressure: standard 20-200 psig, optional 0-30, 100-300 psig
QUICK SIZING:
Valve size one or two sizes smaller than main line.
Points to consider:
– Refer to Engineering Data - Flow Capacity Chart

CHECK VALVE W/ SEPARATE OPENING
& CLOSING SPEED CONTROLS
Valves 4" & smaller (6" & Larger use 118-4R/6118-4R)
The ACV 118-3R permits flow when inlet pressure exceeds outlet
pressure. Should pressure reversal occur the valve closes drip-tight.
Opening and closing speeds are separately adjustable.
118-R - no speed control
118-1R - no closing speed

4" & smaller
118-4R - Separate opening and closing speed (6" & Larger)
QUICK SIZING:
Valve size same as line.
Points to consider:
Distribution flow:
– Refer to Engineering Data - Flow Capacity Chart
– Pressure drop at required flow.
Refer to Engineering Data - Pressure Drop Chart.
Check Flow
– If check flow velocity exceeds valve chart, consider
adding a relief valve (ACV 116) to your system
VALVE FUNCTION
– Valve closes at a controlled rate (adjustable) when outlet/downstream
pressure exceeds inlet/upstream pressure
– Valve opens at a controlled rate (adjustable) when inlet/upstream
pressure exceeds outlet/downstream pressure
