Technical Data
Medium:
Smooth Start Valves: Filtered and lubricated compressed air or
vacuum.
3-Port/2-Position Time Delays: Filtered, nonlubricated dry
compressed air.
Other Time Delays: Filtered (5-micron), nonlubricated, dry
compressed air at a constant pressure and temperature. The
finer the filtration and the closer the regulation, the better the
accuracy and repeatability of the time delay.
Mounting:
Through-holes in valve body, in-line, or on valve.
Port Size:
Smooth Start Valves: 1/4" – 1-1/4" BSPP, PTF, or ISO Rc.
3-Port/2-Position Time Delays: 1/4" BSPP, PTF, or ISO Rc.
Operating Pressure Range:
Smooth Start Valves: 2.1 to 20.7 bar (30 to 300 psig).
3-Port/2-Position Time Delays: 2.1 to 10.3 bar (30 to 150 psig).
Other Time Delays: Equal to or greater than main valve inlet
pressure but not less than 2.1 bar (30 psig) and not greater
than 10.3 bar (150 psig).
Operating Temperature:
Smooth Start Valves: -29° to 79°C (-20° to 75°F).
All Time Delays: 2° to 54°C (35° to 130°F).
Consult Technical Service for use below +2°C (35°F).
Materials:
Body: Aluminum alloy body, acetal, or aluminum check valve,
stainless steel adjusting screw.
Elastomers: Nitrile rubber seals.
