Gate valve

Iím about ready to explode. Leaving the camp ground and at the dump station. Full black tank. The gate valve under the black tank wonít open. The valve handle is not connected to the gate and is loose! What can I do?

Push down and turn it clockwise for five or six twists.
Then pull up.
Below is a link to most of my modifications either accomplished or pending.

Hello. I had hardly any internet connection to get replies but we did figure it out. The handle would not re-connect. Fortunately a friend was nearby and had a Dremel I used to cut away the sleeve where the valve seats. I pulled out the gate with some pliers, not entirely a clean job as you can imagine. The black tank emptied to the next gate where I opened that and it free-flowed and emptied into the dump station where I did this job. Thankfully there was no one waiting to use it. I will be replacing the valve today. I can only imagine how much it would cost to have an RV mechanic do this, especially with a full tank. My dealer doesn’t have a dump station so I don’t know what we would have done. Plus, driving 400 miles with a full black tank might have ended in disaster.
