115-4 (Globe) / 1115-4 (Angle)
PRESSURE REDUCING / SOLENOID ON-OFF
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 solenoid override feature allowing for
electrical on-off operation of the valve.
NOTE:
Adjustment range:
Standard: 20-175 psig
Optional: 0-30 psig
100-300 psig (uses stainless
steel control)
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
Additional combinations:
115-5 Pressure Reducing/Solenoid/Check
SPECIFY:
Energized to open or energized to close main valve.
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 6115-4
Consult Watts ACV representative/factory
PRESSURE REDUCING
Flow Direction Shown: Under the Seat
Optional ‘R’ Flow Over the Seat: 115-4R/1115-4R
115-7 (Globe) / 1115-7 (Angle)
PRESSURE REDUCING / SURGE
Automatically reduces a higher inlet pressure to a constant lower
outlet pressure regardless of changing flow rate and/or varying inlet
pressure. Should flow rate decrease rapidly a pressure controlled
surge pilot closes the valve to prevent downstream pressure buildup.
Excellent in dead-end systems and/or systems using high demand,
on-off equipment.
NOTE:
Adjustment range reducing/surge:
Standard: 20-175 psig
Optional: 0-30 psig
100-300 psig
(stainless steel control)
Additional combinations:
115-43 Reducing/Surge/Sustaining
115-50 Reducing/Surge/Check
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 6115-7
Consult Watts ACV representative/factory
