Norgren Time Delay Valves consist of a 0 to 60 second time delay fitted with an A1 air operator and a special bottom cap with IN and OUT
ports. They are used to provide delayed actuation or release of valves or other pneumatic devices that do not require large air flows.

Smooth Start Valves
Norgren Smooth Start Valves are 2-port/2-position, spring return, normally closed valves. They are used in compressed air systems to retard the rate
of downstream pressure buildup at start up. Cylinders and other air operated devices are eased into positions corresponding to initial system
pressurization, reducing the possibility of equipment damage and hazards to the user. Application of full downstream pressure can be delayed for as
long as 50 seconds, depending on the setting of the adjustable needle valve and downstream air volume. Smooth start valves never shut off
completely and must be installed downstream of a directional control valve, such as a Norgren Poppet Valve listed on the preceding pages.
