Spirax Sarco has produced a movie demonstrating the principles of operations of its Model 25 Series pilot operated pressure reducing valves. The 25 Series was first introduced in 1959 as a versatile and simplistic family of self-acting pressure regulators with control pilots and interchangeable main valves for most steam applications. The interchangeable springs allow quick and easy change of downstream pressure range eliminating the need to isolate the valve or break the steam line.  The internal components are made of stainless steel for durability and corrosion resistance.  The fatigue-tested diaphragm is designed without a piston which prevents danger of sticking.
