The Role of Steam Pressure Reducing Valves
Enabling Efficiency in Your Steam System
Steam PRVs reduce pressure from high-pressure distribution lines to the lower levels required at points of use, providing automated pressure control without the need for external power. With over 80 years of industry experience, Fisher™ Steam PRVs are trusted to deliver accurate, reliable control for both wet and dry steam—improving efficiency, protecting equipment, and driving cost savings. Proper PRV sizing considers inlet and outlet pressure, flow rate, temperature, and steam quality/dryness—the proportion of vapor to liquid in the steam. Best practices include incorporating a bypass line for maintenance, isolation valves for safety, and steam traps to remove condensate and extend system life.

Controlling Pressure for Safe Steam Delivery
Steam PRVs automatically regulate downstream pressure without external power. They balance spring force and steam pressure to satisfy flow demand downstream at a desired setpoint. Used in direct-acting or pilot-operated designs, they’re one part of a full system ensuring safe, efficient steam control.
