There are various types of pressure control valves in the market today, this article will focus on stainless steel air pressure regulators that are designed to reduce and maintain stable outlet air pressure regardless of inlet pressure changes. Changes in air pressure system demands, air pressure reserves combined with changes in compressor minimum and maximum settings mean that compressed air pressures will change quite dramatically. This is compounded when high flow demands require high system air pressures or automation systems require high or low stable air pressures to operate. The best way to control air pressure supply to key pneumatic equipment is to install an air pressure regulator sometimes known simply as an air pressure reducing or regulating valve.
316 Stainless steel air pressure regulators are made entirely from 316 stainless steel, that means everything except the elastomer seals including the body, internals, handle, piston, locking nut, filter element, mounting bracket and screws are 316 stainless steel, except only the pressure gauge case that is 304 stainless steel. This makes this all stainless construction ideally suited for the offshore, food, petrochemical and semiconductor industries.
