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.
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
