About the Airtac 7V Solenoid Valve 7V22008B050
With a DC24V coil and a 0.5 m lead, the AirTAC 7V22008B050 is a 5/2-way double-solenoid valve with PT1/4 supply and outlet ports with PT1/8 exhausts. A pulse on either coil shifts the spool and it stays there until the other coil is pulsed, so it keeps its position through a power cut. The catalog flow on PT1/4 is 14.7 mm2 (Cv 0.87). The DC24V coil (code B) draws 0.7 W, is class F and dust-protected, responds in 0.05 s or less and plugs in horizontally or vertically; the 050 code gives a 0.5 m lead.
It is pilot operated from 0.15 to 0.8 MPa (21-114 psi) on air filtered to 40 um, proof pressure 1.2 MPa, -10 to +50 C, at up to 5 cycles/s, and weighs 135 g. The die-cast aluminum-alloy body collects the pilot exhaust and vents it through the R and S ports. No lubrication is needed; once lubricated air is used, keep using it with ISO VG32 oil.

How to choose
Within the 7V220, AC220V, AC110V and DC12V coils replace the B with A/C/F; 7V22008B200 has the 2.0 m lead; the other ports of this body are Dia 8 mm push-in (7V220J08B050) and Dia 10 mm push-in (7V220J10B050). The same body comes as 7V210, 7V230C, 7V230E and 7V230P: 10 single solenoid, 20 double solenoid, 30C/30E/30P the 5/3-way centers. PT threads are standard; G (BSPP) and NPT are marked G and T at the end of the code. Several 7V200 valves can share a 7V200M manifold base of 1 to 20 stations.
Applications
Holds position on power loss
A pulse from a 24 V DC PLC output switches the cylinder and the valve keeps that position until the other coil is pulsed.
Machine pneumatics
Cv 0.87 on PT1/4 suits medium cylinders.
DC24V control circuits
The DC24V coil connects to a 24 V DC PLC output; the 0.5 m lead plugs into the coil terminal.
FAQ
What are the key figures of the 7V22008B050?
5/2-way double-solenoid valve, 7V200 series; PT1/4 ports; catalog flow 14.7 mm2 (Cv 0.87); 0.15-0.8 MPa (21-114 psi), proof 1.2 MPa; -10 to +50 C; up to 5 cycles/s; DC24V coil, 0.7 W, class F; 0.5 m lead; response 0.05 s or less; 135 g.
What does the 7V22008B050 do with the coils off?
A pulse on either coil shifts the spool and it stays there until the other coil is pulsed, so it keeps its position through a power cut.
