Smooth Start Valves and
TIme Delay Options
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, inline, or on valve.
Port Size
Smooth Start Valves: 1/4" – 1-1/4" PTF, BSPP, or ISO Rc.
3-Port/2-Position Time Delays: 1/4" PTF, BSPP, or ISO Rc.
Operating Pressure Range
Smooth Start Valves: 30 to 300 psig (2.1 to 20.7 bar).
3-Port/2-Position Time Delays: 30 to 150 psig (2.1 to 10.3 bar).
Other Time Delays: Equal to or greater than main valve inlet
pressure but not less than 30 psig (2.1 bar) and not greater than
150 psig (10.3 bar).
Operating Temperature
Smooth Start Valves: -20°F to 75°F (-29°C to 79°C).
All Time Delays: 35°F to 130°F (2°C to 54°C).
Consult Technical Service for use below 35°F (+2°C).
Materials
Body: Aluminum alloy body, acetal, or aluminum check valve,
stainless steel adjusting screw.
Elastomers: Nitrile rubber seals.
