You have to loosen the front half of the valve with a long flatblade screwdriver from the front of the rifle. Use a dowel and drive it out from the rear. There should be minimal resistance.

There is also a screw holding the valve on the bottom.

If you look in your manual, it's the screw no. 0500 - valve set screw. Just in front of the long threaded rod that holds the stock on.

The stock retaining stud (and the front breech screw) also locates the steel block behind the valve.... You have to remove that to push it and the valve our from the back....

Why do you want to remove valve is there something wrong with it or are you look to mod it ?

There are several ways you could remove it one is by making a valve tool like this one.
http://www.youtube.com/watch?v=riHZoknkFHg

or by how Bob explained it.

Or you can take out the valve retaining screw and push the complete assembly out the front useing a wood dowel with a 1/8 inch hole drilled in the center of it, slide the valve stem in the hole and then tap out toward the piercing cap end. This will save the seal on the valve it can be reused many times if you don't cut it tapping it out the front. The slots cut in the rear of the tube can cut it. Putting a couple drops of synthetic oil down the front of the tube will make the valve slide out easier. Just make sure to unscrew it a 1/4 to 1/2 turn before removing it. And don't forget to tighten the valve on reassembly doesn't have to be real tight just good and snug.
