Air controlled solenoid valve
We have this solenoid valve that is controlled by air rather than electricity. Its kind of hard to explain. It looks exactly like a normal double acting solenoid valve except it has two more holes for the air to control the valve.
The reason we decided to use a air controlled valve rather than an electrically controlled one was because the airflow was very restricted with our original solenoids. The problem is the air controlled valve is huge. It has output holes at 3/8" diameter. We're not sure if this is legal. Below I've attached a picture of the box it came in. One of the teachers took it with him to find connectors for it. Any suggestion as to whether this is legal or not is appreciated. |

Re: Air controlled solenoid valve
This is not a solenoid valve at all.
Solenoid valves are controlled by a solenoid, which is basically an electromagnet. This allows them to be activated electrically. What you have there is an air-op valve. It, as you said, is controlled by a change in air pressure. As far as I know, air-op valves are not legal for FRC use. I could be wrong on that though. |

Pneumatically controlled valves are not legal on FRC robots, nor are valves with greater than 1/8" NPT ports. |

Re: Air controlled solenoid valve
I think the regular Pesto FRC approved solenoids are good enough. They are actually electric and air actuated.
There is an electric solenoid that allows air to a pneumatic plunger which then switches the ports. That's why you have to have air to those solenoids for them to switch. They can also be a little complex to open up and clean as I did with 3 of ours. I was also a little interested in the insides anyway. |

Can we bypass using solenoids by using a servo to release the air into the solenoids.

Re: Air controlled solenoid valve
Basically. No. Valves you can use are limited. Q&A has essentially said you cannot use a servo to turn a valve. In other years, they had a different answer.
