RATE OF FLOW
PRESSURE REDUCING
114R (Globe) / 1114R (Angle)
RATE OF FLOW (“R” indicates over the seat flow)
Maintains a constant flow rate, adjustable, regardless of fluctuations
in line pressure. The rate of flow pilot senses the differential pressure
across a thin edged orifice plate mounted in the valve inlet flange. It
responds to changes in pressure and modulates the main valve to
maintain the desired flow.
SPECIFY:
Desired flow rate at time of order.
ACV 114R: flow over the seat (fail closed)
ACV 114: flow under the seat (fail open)
Additional combination functions:
114-1R Rate of Flow / Solenoid On-Off
114-2R Rate of Flow / Pressure Reducing
114-8R Rate of Flow / Pressure Sustaining
QUICK SIZE: Stay within parameters of capacity chart (below)
Points to consider:
– Orifice plate sized per application and per your
acceptable pressure drop - consult factory
VALVE FUNCTION
–
Limits flow rate to a constant preset maximum (adjustable)

115 (Globe) / 1115 (Angle)
PRESSURE REDUCING
Automatically reduces a higher inlet pressure to a constant lower
outlet pressure regardless of changing flow rate and/or varying inlet
pressure. Refer to ACV 115-7 for dead-end systems and/or systems
using high demand, on-off equipment.
NOTE:
Adjustment range:
Standard: 20-175 psig
Optional: 0-30 psig
100-300 psig
(stainless steel control)
Remote sense: ACV 115-1
QUICK SIZING:
Valve size one size smaller than line.
Points to consider: –
– See Engineering Data - Pressure Reducing Sizing
– Check maximum and minimum flow
– Check pressure drop - pressure reducing valves or cavitation chart
– If valve size required is smaller than line size, consider ACV 6115
Consult Watts ACV representative/factory
