0 to 5 Second Time Delays, & 0 to 60 Second Time Delays - Standard Applications and Special Applications
For Use With Air and Solenoid Operated Poppet Valves
Most Norgren solenoid and air operated poppet valves can be equipped with an adjustable 0 to 5 or 0 to 60 second time delay. Both available in two
functional models.
(1)
Time Delay on Operation (TDO), which delays shifting of the main valve poppet on application of the pilot signal, and releases the poppet
immediately upon removal of the signal, and
(2) Time Delay on Release (TDR), which shifts the main valve poppet immediately upon the application of the pilot signal, and delays release
of the poppet on removal of the signal.
Norgren Air Pilot Operated Poppet Valves can be equipped with a Special Application 0 to 60 second One Shot Model, which shifts
the main poppet respectively upon application of the pilot signal and releases the poppet after the time delay period is completed.
Ordering Information
● USE ONLY WITH valves as defined in the following diagram.
● To order valves with a time delay, note the desired valve model number from previous pages in Section 10. Insert the desired time delay model
number in the 7th and 8th positions of the valve model number as shown in the following diagram. For example: for a 4-Port/2-Position Air Pilot
Operated Inline valve, F1024C-00-A1, with a 0 to 5 Second Time Delay on release order: F1024C-02-A1.
● FOR 0 TO 5 SECOND TIME DELAY - DO NOT USE WITH 2" basic valves.
● FOR 0 TO 60 SECOND ONE SHOT SPECIAL APPLICATION - DO NOT USE WITH 3-way twin valves.
NOTES:
* Valves with an internal pilot supply are identified by a C in the 6th position of the model number. See Figure 1(on following page) for installation.
ALTERNATE CONFIGURATION - MODE - 23 ONE SHOT TIME DELAY: The Alternate Configuration of Model 23 Time Delay (see next page
for description) requires an unrestricted internal pilot supply passage. Select the desired valve model number as described above, then
change the 6th position of the model number to B, i.e. D1022B-23-A1, when ordering Model 23 Alternate Configuration. See figure 1 for installation.
When used with valves that have an external pilot supply (designated by an H or J in the 6th position of the valve model number), the pilot
supply must be connected to the operator (Figure 2). Zero to five second time delays do not have an external pilot supply port.
** An adjustment screw provides an adjustment range of 0 to 5 or 0 to 60 seconds.
For 0 to 60 second ONLY this range can be extended by increasing the volume of the time delay cavity in the timer body. A port is provided in
the body for connecting an additional external cavity which can consist of a short length of pipe (capped at one end) or other similar air receiver.
Increasing the cavity an additional 29.5 cubic cm., (1.8 cubic inches) will roughly double the delay time for the same adjustment screw
setting.There must be an A, B, C, D, E, or F in the 1st position of the desired valve model number.
There must be an A, B,
C, D, E, or F in the 1st
position of the desired
valve model number. There must be a C, H,
or J in the 6th position
of the desired valve
model number.*
