The integral automatic flow rate cartridge maintains the flow rate in the controlled circuit.
The optimum flow rate is maintained at a constant level even under fluctuating pressure conditions
from as little as 2 PSI to as much as 60 PSI of differential pressure.
In a properly designed system the valve automatically ensures system balance, regardless of changing
pressure conditions normally associated with variable speed pumping.
Integral P/T-ports for needle
system and/or drain are available as options, as are a variety of end connections on
valves from 1/2" to 2 1/2" in size, with either female NPT or sweat fixed ends, and a union end with
sweat, female NPT or male NPT. Valves are normally equipped with 1" long capped readout ports fitted
with internal check valves.
