Description: NEMA 4X FLOW SW,SS Bellows&Pad
Category: Hydronic Controls
Sub Category: Flow Switches
F61 Series Flow Switches
The F61 Series Flow Switches respond to fluid flow in
lines carrying water, ethylene glycol, or other
nonhazardous fluids. Two subseries are available.
F61 Series Sensitive Flow Switches respond to low
fluid flow rates in applications with pipe sizes under
1-inch trade size.
F61 Series Standard Flow Switches use a variety of
paddle sizes to respond to fluid flow rates in
applications with pipe sizes greater than 1-inch trade
size.
Single-Pole, Double-Throw (SPDT) and Single-Pole,
Single-Throw (SPST) open-low versions of these flow
switches are available.
Features and Benefits
❑ NEMA 3 or NEMA 3R
Enclosure on Selected Models
Allows use in indoor or outdoor applications
❑ Stainless Steel Bellows on
Selected Models
Allow use in fluid lines carrying chlorinated water,
treated water, or other nonhazardous fluids
❑ Low-Flow Operation on
Selected (Sensitive) Models
Actuates switch with less than 1.0 GPM (3.8 L/min)
flow for water applications or 9.0 GPM (34.1 L/min)
flow for steam applications
❑ Gold-Plated Contacts on
MG Models
Reduces intermittent contact problems in
low-voltage and low-current circuits
❑ Maximum Fluid Pressure
of 150 psig (1034 kPa)
Permits use in a wide range of pressure flow
conditions
IMPORTANT: All F61 Series Flow Switches are
intended to control equipment under normal
operating conditions. Where failure or malfunction of
an F61 Flow Switch could lead to an abnormal
operating condition that could cause personal injury
or damage to the equipment or other property, other
devices (limit or safety controls) or systems (alarm or supervisory) intended to warn of, or protect against,
failure or malfunction of the F61 Flow Switch must
be incorporated into and maintained as part of the
control system.
! CAUTION: Risk of Equipment Damage.
Do not use F61 Series Flow Switches with
hazardous fluids or in hazardous atmospheres. Use
in these conditions may cause malfunction or
improper operation.
IMPORTANT: F61 Series Flow Switches must not
be used where the fluid in the pipes drops below the
fluid’s freezing point, causing an internal freeze-up.
