F6/F7…HS/HSU Series Butterfly Valves
Resilient Seat, 304 Stainless Disc with AM/AR, GM/GR and AF Series Electronic Actuation
• 50 psi bubble tight shut-off (HSU Series)
• 200 psi bubble tight shut-off (HS Series)
• Long stem design allows for 2” insulation
• Valve face-to-face dimensions comply
with API 609 & MSS-SP-67
• Completely assembled and tested, ready
for installation
• Tees comply with ASME/ANSI B16.1 Class flanges
Application
These valves are designed to meet the stringent needs of
HVAC and Commercial applications requiring positive shut-off
for liquids.
Typical applications include chiller isolation, cooling tower isola-
tion, change-over systems, large air handler coil control, bypass
and process control applications.The large Cvvalues provide for
an economical control valve solution for larger flow applications.
Designed for use in Victaulic piping systems when mated to
Victaulic 41 series flange nipples.
Jobsite Note:
Valves should be stored in a weather protected area prior to
installation. Complete installation recommendations on page 38.

Dimension “A” is compressed, add .125” for relaxed state. Maximum actuator ambient temperature is 150°F.
Model SY1… does not have hand wheel - override is via 8mm wrench on bottom side of actuator.
Application Notes:
1.Valves are rated at 200 psig differential pressure in the closed position, (150 psi 14” and larger).
2.Valves are furnished with lugs tapped for use with ANSI Class 125/150 flanges.
Installation flanges and hardware are not included.
3.3-way assemblies are furnished assembled and tested, ready for installation. All 3-way assemblies require the customer to specify
the 3-way configuration prior to order entry to guarantee correct placement of valves and actuators on the assembly.
4.Dimension “D” allows for actuator removal without the need to remove the valve from the pipe.
5.Belimo SY Series actuators are NEMA 4, 4x rated.
6.Bolts supplied are for shipping purposes only. Upon installation, replace with an appropriate SAE grade 5 or better hardware.

Wire size vs. length of run for SY Series Actuators
The NEC mandates that 24 VAC over 100VA power requires CLASS 1 wiring conduit. Local Codes may vary. Do NOT mix CLASS 1 & CLASS 2 circuits in the
same conduit. Generally, 24 VAC actuators over 100VA should be changed to 120 VAC models.

Transformer sizing = SY actuator draw X 1.25 (safety margin)
(Ex. SY2-24 requires 3.0A x 1.25 = 3.75A,
3.75A X 24 VAC = 90VA Transformer).
Indicates an action or condition that may cause irreversible
damage to the actuator(s) or associated equipment.
Equipment damage!
Power consumption and input impedance must be observed.
CAUTION
Indicates a potentially hazardous situation which, if not avoided,
may result in minor or moderate injury.It may also be used to
alert against unsafe practices.

NOTES SY1…5-24
Each actuator should be powered by a single, isolated
control transformer.
• Isolation relays must be used in parallel connection of multiple actuators
using a common control signal input.
• "H" cannot be connected to terminal #3 and #4 simultaneously.
•Required: Terminal #7 needs to be field wired to enable heater circuit.
