Product Description
Norgren P72E-3AN-NNN General Purpose Soft Start Valve
PN: P72E-3AN-NNN
Soft start valves allow a controlled increase of pressure onto downstream cylinders/machines offering protection to personnel and equipment.
- EXCELON design allows in-line or modular installation
- High-flow, spring return, 2 port/2 position normally closed valves
- Reduces rate of downstream air pressure buildup at system start up
- Cylinders and other air operated devices are eased into normal starting positions, reducing the possibility of equipment damage and hazards to the user.
- Adjustable rate of pressure increase
- Cushioned poppets for long service life
- Port Size: 3/8"PTF
- Fluid: Compressed air
- Maximum pressure: 17 bar (250 psig)
- Minimum operating pressure: 3 bar (44 psig)
- Temperature range*: -20° to +65°C (-0° to +150°F)
- Ports: PTF ports, ISO G ports, ISO Rc ports
- Maximum flow with 6,3 bar (90 psig) inlet pressure and pressure, drop of 0,5 bar (7 psig): 21 dm3/s (45 scfm)
Snap pressure:
- Full flow when downstream pressure reaches 50 – 80% of inlet pressure
- Charge time: For 2 litre (0.53 gallon US) downstream volume and 6,3 bar / (90 psig) inlet pressure / 0,8 sec. minimum / 76 sec. maximum
- Average flow factor (Cv): 1,35
Materials:
- Body: Zinc alloy
- Elastomers: Synthetic materials
- Internal components: Brass/steel
