Flanged PICV Valve.
Description
Pressure Independent Control Valves automatically adjust
to differential pressure changes, providing constant ow in
HVAC systems. This reduces “hunting” for the right setting,
and results in better control and increased comfort. Overall
system performance can be optimized with PICV, requiring
less pumping energy and contributing to more efcient
loading of boilers and chillers.
Siemens Pressure Independent Control Valves integrate
three functions into a single device: control valve,
adjustable ow limiter, and automatic pressure regulator.
The 2-1/2 and 3 inch valves have a 20 mm stroke and use
the SAX non-spring return electronic valve actuators and
the new SQV spring return electronic valve actuators.
Features
• 3-in-1 device includes a control valve, eld adjustable
ow limiter, and automatic pressure regulator.
• Full stroke regardless of maximum ow setting.
• Maximum ow preset is easily eld adjustable.
• Choice of low ow (up to 110 gpm for 2.5 inch and
150 gpm for 3 inch) or high ow (up to 154 gpm for
2.5 inch and 190 gpm for 3 inch) versions
• Available in both ANSI 125 and ANSI 250
pressure classes.
• Both SQV actuators (normally open and normally
closed) can be wired for oating, 0-10V or 4-20 mA
control signals
Applications
Typical applications include control of hot or chilled water
or water-glycol solutions up to 50% in closed
loop systems.
