Service Notice:
• The Series 63-N4 is not repairable. When
any performance problems are detected
during routine inspection, replace valve
immediately.
• For S63-N4/N7 Solenoids, see O&M In-
structions for information on: Wiring,
Solenoid Temperature, Cause of Improper
Operation, and Coil Replacement.
DESCRIPTION
Series 63 valves are 3-way or 4-way, 5 ported 2
position piloted spool type single or dual sole-
noid valves designed for air or inert gas service.
Valves are made of rugged anodized aluminum.
A built-in manual operator allows manual opera-
tion when desired or during an electrical power
outage. Each valve may be used for 3-way (nor-
mally closed) or 4-way operation by using the
appropriate flow plate provided. Flow plates are
marked (3/2) for 3 Ports, 2 Positions (3-way op-
eration) or (5/2) for 5 Ports, 2 Positions (4-way
operation). These valves are supplied with all
necessary hardware for a NAMUR direct mount
installation i.e. flow plates, gaskets, mounting
screws and a locating set screw. See Flow Selec-
tion And Mounting section.
APPLICATIONS
Typically, the 3-way (3/2) normally closed mode
is used for a single acting (spring return) actuator;
4-way (5/2) mode for a double acting actuator.
Port Markings: 1 = Supply, 2 & 4 = Open/Close
Actuator ports 3 & 5 = Exhaust
OPERATION
NOTE: Minimum operating supply pressure,
differential 30 psi; maximum 150 psi.
Breather Function 3-way (3/2) mode only: Al-
lows for spring side of a spring return actuator to
vent at all times through valve exhaust port 3.
Single Solenoid: This type of operation is used
where automatic return of the valve on electri-
cal power failure or loss of main line pressure
is required.
