Fixed Flow Control (FC)
A pressure compensated
automatic fixed flow device,
designed to limit the flow GPM
through the coil. This inline version
comes with a fixed flow rate in a
tamperproof housing. Desired
GPM must be specified.
Nominal size: 1/2" or 3/4"
Flow Range: 0.5 – 20.0 GPM
options
Body material: Copper
Pressure differential range: 2 – 80
psid
Temperature rating: 220ºF max.
Cv: Variable with inlet pressure
2-Way Modulating Control
Valve / Actuator
Valve operation is described
above. Actuators use a 0 – 10
Vdc control signal, are fail-in-
place design (non-spring return)
and provide proportional control
from minimum to maximum
water flow through the coil in
response to room demand from
a compatible controller.
Modulating valves are standard
on Nailor analog and digital
EPIC control package chilled
water valves.
Actuator are 3-wire 24 Vac only
(2.5 VA).
3-Way Modulating Control Valve
/ Actuator
Valve operation is described
above. Actuators use a 0 – 10 Vdc
analog control signal, are fail-in-
place design (non-spring return)
and provide proportional control
minimum to maximum water flow
through the coil in response to
room demand from a compatible
controller. Modulating valves are
standard on Nailor analog and
digital EPIC control package chilled
water valves.
Actuator are 3-wire 24 Vac only
(2.5 VA).
Flexible Hose Kits (FH)
See full description elsewhere in
catalog. Standard on all Vertical
Hi-Rise Units.
Core: Fabric reinforced EPDM
Braid: Stainless Steel
Fiting: Brass OT58
Ferrule: Stainless Steel
Gasket Seal: Fiber / EDPM
Cv: 3.5 (1/2"), 12.8 (3/4")
Adjustable Flow Circuit Setter
(AFS)
A pressure dependent ball type flow
control device, precisely calibrated
for use as a presettable balance
valve, variable orifice flow meter and
positive shut-off service valve.
Furnished with a calibrated
nameplate and memory stop
indicator and built in P/T ports.
Nominal size: 1/2" or 3/4"
Pressure rating: 200 psig max.
Temp. rating: 250ºF max.
Body material: Brass
Ball: Brass
Cv: Variable
Cartridge Fixed Flow Control
(FCC)
A pressure compensated
automatic fixed flow device,
designed to limit the flow through
the coil. This model features a
changeable flow cartridge. Y-design
allows changing the flow rate
without dismantling the piping.
Nominal size: 1/2" or 3/4"
Body material: Forged brass
Flow Range: 0.5 – 8.0 GPM options
Pressure differential range: 2
– 80 psid
Temperature rating: 220ºF max.
Cv: Variable with inlet pressure
