Steam Pressure Reducing Valve Manufacturer in Europe – Valvesonly Europe (Germany) 

Valvesonly Europe designs steam pressure reducing valves (PRVs) for stable, accurate control of downstream steam pressure in generation and distribution networks. Built in Germany to PED and EN/ASME standards with documented performance testing. 

Function & Working 

PRVs reduce a higher inlet steam pressure to a controlled outlet setpoint. Direct-acting designs use spring force against a diaphragm; pilot-operated designs use a pilot valve sensing downstream pressure for high accuracy and capacity. 

Advantages 

• Tight outlet pressure control across wide load changes 

• Options for saturated and superheated steam 

• Stainless/stellited trims for erosion resistance 

• Low droop; minimal hunting with pilot-operated types 

• Optional condensate-resistant internals 

Types Offered 

Direct-Acting • Pilot-Operated • High-Pressure PRV • Desuperheating PRV (with water injection)
