Specifications

13
115-2 (Globe) / 1115-2 (Angle)
PRESSURE REDUCING / SUSTAINING
Automatically reduces a higher inlet pressure to a constant lower
outlet pressure regardless of changing flow rate and/or varying inlet
pressure. Equipped with a pressure sustaining control which prevents
the upstream pressure from dropping below a preset minimum.
NOTE:
Adjustment range:
Standard: 20-175 psig
Optional: 0-30 psig
100-300 psig
(stainless steel control)
Additional Combinations:
115-11 Reducing/Sustaining/Check
115-32 Reducing/Sustaining/Solenoid
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 6115-2
Consult Watts ACV representative/factory

115-3 (Globe) / 1115-3 (Angle)
PRESSURE REDUCING / CHECK
Automatically reduces a higher inlet pressure to a constant lower
outlet pressure regardless of changing flow rate and/or varying inlet
pressure. Equipped with a hydraulic check feature to prevent reverse
flow on pressure reversal.
NOTE:
Adjustment range:
Standard: 20-175 psig
Optional: 0-30 psig

(stainless steel control)
QUICK SIZING:
Valve size one size smaller than line.
Points to consider: –
