To install the new valve, first attach the valve to its hose. This is much easier to do now than when the valve is installed in the engine. If your valve is mounted in a convenient location, just press it into place and you're done. If it's less than convenient, grasp the PCV valve with your pliers and carefully press it in.
Tip: If your having a hard time getting the new valve to slide in, use a little motor oil as lubricant. Never use anything but oil.
