Description: 3-WAY AIR VALVE 277 V
Category: Valves
Sub Category: Solenoid Valves
V11 Series
Three-Way Solenoid Air Valve
Application
V11 three-way valves are for use
in applications where the
operation of a pneumatically
operated device is dependent
upon an electrical circuit.
The valves direct supply air to
the pneumatic device when the
coil is energized or deenergized,
depending on the
supply and exhaust air
connections.
All Series V11 air valves are
designed for use only as
operating devices. Where
system closure, improper flow,
or loss of pressure due to valve
failure can result in personal
injury and/or loss of property, it
is recommended that additional
devices be added to indicate
proper system operation, (for
example, blade position
indication on the damper blades
in smoke damper applications).
Features
· Positive air seal.
· Some models may be
manually operated for testing
and checkout.
· Compact and lightweight.
· Can be mounted in any
position.
General Description
The solenoid air valve is
furnished for two-position action
and has three identified
connections: a normally open
(N.O.) port with 1/8 in. FNPT
connection, a normally closed
(N.C.) port and a common
(COM) port with 1/4 in. barbed
fittings. The ports in the diecast aluminum valve body have
No. 60 mesh (217 micron
openings) monel screens to
avoid allowing foreign material
from entering the valve ports to
give positive air seal.
In a typical application, supply
air is connected to the normally
closed port and the control
device is connected to the
common port. When the
solenoid is energized, a
magnetic field activates a
plunger-type valve stem and
supply air is directed to the
control device. When the
solenoid is de-energized,
the
supply air connection is closed
and the normally open port
exhausts air from the control
device. Reverse action may be
obtained by connecting the
supply air to the normally open
port, using the normally closed
port for exhaust.
