VP60

Proportional flow and directional control spool valve

Technical features

Medium	Air acc. to ISO8573-1 Grouping: 2-3-1, filtered (recommended < 3 μm), dried, non lubricated. The dynamic performance and service life of the valve may be significantly reduced if using unfiltered air containing water and oil!
Operating pressure on all ports	-1 … 16 bar (-14 … 232 psi)
Pneumatical flow coeff.	C = 290 Nl/(min bar)
Critical pressure ratio	b = 0,1 … 0,4
Calibrated flow rate (Qmax.)	1200 Nl/min at P1 = 6 bar (87 psi), P2, P4 = 5 bar (72 psi) Imperial vals. for 8 Nl/min -> 0.0081 Cv
Leakage	Typical value: 8 Nl/min at (P1 = 10 bar (145 psi), P2/P4 = 0 bar)
Port size	G1/4, 1/4 NPT or flange mounted according ISO 1
Spool deadtime	3 ms max
Risetime 10 ... 90%	5 ms
Threshold frequency -3dB	105 Hz
Service life	> 250 million full stroke operations with recommended air quality
Ambient/Media Temperature	Ambient: 0 … +60°C (+32 … +140°F) Media: +5 … +60°C (+41 … +140°F)
Storage temperature	-20 … +80°C (-4 … +176°F) Condensation not permitted! Air supply must be dry enough to avoid ice formation at temperatures below +5°C (+41°F).
Materials	Electronic enclosure: PAA Valve housing and internal parts: anodised aluminium Other static seals: NBR Actuator magnet: Fe, surface refined
