I am tring to follow the footsteps of others and automate my Dad's DC. I have gates and I am on the lookout for cylinders. Now for valves, are these what I need:



Media:Air
Action:Internally piloted
Type:5 Port 2 position
Orifice size:16mm²(CV=0.78)
Port size:IN-OUT 1/4"PT,Exhaust 1/8"PT
Lubrication:Not required
Pressure range:1.5-8kgf/cm²
Proof pressure:12kgf/cm²
Temp. range:-5~60℃
VoltageC12V Single electrical control
Power consumption:3VA
Insulation:F Class
Protection:IP65
Connection:Socket with plug
Max. frequency:5 cycles/s
Min. activate time:0.05second
Package: 1*5 Port 2 position Pneumatic Air Solenoid Valve 1/4" DC12V I figure 12V from manual switch or automatic current sensor into a timer ( for delay ) to gate control. I believe using these valves, with needle valves on the exhaust ports, will enable to operate a small double action cylinder with some reasonable control.
If not, what type of valve?

Thx's, Fred.

Alan Schafter is the go to guy here. My valves are on a manifold- easier for me to deal with and better bargains on ebay. SY 3140 or 5140. I believe they are 5 port 2 way as is yours. Mine are 5LOZ which are 24 volt. The nice thing about the manifold is you can find them with the push in fittings included. Dave

Yes, Alan is the guy on this setup. Based on my experience with pnuematics and hydyaulics, I would put a flow control plate under the directional valve instead of using individual needle valves on the A/B cylinder lines. Just makes it cleaner.

I can't read the numbers but it looks correct. You need a transformer and then convert to DC. Dave

Current sensor switches are CR Magnetics 9321 PNP as I recall. Dave
