The Type 92B Pressure Reducing Valve (PRV) is the standard steam valve for the industry. It can withstand dirty operating environments while providing accurate and stable pressure control.
The Type 92B steam valve is designed to provide decades of continuous service, and is applied as a main pressure reducing valve in industrial process heating applications such as heat exchangers, evaporators, digesters, and reactors.
It is diaphragm actuated, thus providing a simple, accurate, and easily maintained valve. The Type 92B steam valve is rated for inlet pressures to 300 psig (20,7 bar) at 600°F (316°C). The inlet (upstream) steam operates the pilot in this self-powered control valve.
