The 26 flow stabilizer is a self-cleaning, opening speed control.

It is used in conjunction with a fixed restriction orifice that is usually threaded into port 3. The 26 stabilizer allows free flow down to the bonnet (port 1) and restricts flow up from port 1.

The 26 stabilizer is used as the standard flow stabilizer (opening speed control) on model 106-PR or 206-PR pressure reducing valves or any other model that requires low flow stabilization.
