P74F
● Excelon design allows in-line or modular installation
● Controls increase of downstream pressure on
start up. Cylinders and other air operated devices are
eased into normal operating positions, reducing the
possibility of equipment damage and hazards to the
user.
● 3 port/2 position, normally closed, soft start valve
with optional manual lockout slide
● Blocks inlet air and exhausts downstream air when
pilot signal is removed or when the optional manual
lockout slide is closed
● Optional manual slide can be padlocked in closed
position
● Solenoid pilot or air pilot operation
● Designed primarily for use in start-up and shutdown
of equipment, not as a frequently cycling directional
control valve. Norgren offers a wide variety of valves
designed for frequent cycling and other applications.
Please refer to the P72C and P74C valves, and to
other Norgren valve catalogs.
