The SV241, SV242, and SV261
Series valves are 3-way, directacting, and normally closed. The
SV241 and SV242 can be used for
liquids or gases, while the SV261
offers a quick-exhaust feature and is
limited to air use. The most common
application for these 3-way valves is
the control of single-acting cylinders
or spring-return actuators. The
pressure inlet port is blocked in the
de-energized position.
A 3-way normally closed valve has
3 ports labeled 1, 2, and 3. When
de-energized, no flow occurs from
port 1, but there is flow from port 2
to 3. When energized, flow occurs
from port 1 to 2, but no flow occurs
from port 3. Usually,
3-way valves are used
to control larger pneumatically activated
valves. Port 1 is connected to the pressure
source, port 2 is connected to the cylinder
controlling the pneumatic activation, and
port 3 is the exhaust port vented to
the room.
The SV251 is a multipurpose 3-way
valve and can be used as normally open

or normally closed. During
installation, for normally
closed select port 1 as supply
pressure. Port 2 is connected
to the pneumatic cylinder,
and port 3 is the exhaust
port. To configure as normally
open, select port 3 as supply
pressure. Port 2 is connected
to the pneumatic cylinder, and
port 1 is the exhaust port. The
SV251 can be used for liquids
or gases.
The SV271 is a 4-way, 5-ported
solenoid valve, rated for
air applications only. It is a
2-position, pilot-operated valve
typically used to control doubleacting cylinders or pneumatic
actuators. A 4-way valve has
ports labeled 1, 2, 3, 4, and
