Direct-operated Pressure Reducing Valve with Stainless Steel Trim and Adjustable Outlet Pressure for Steam Systems

The VYC 513 (screwed), 514 (flanged) and 614 (high-capacity) are direct-operated pressure reducing valves for steam, water, air and neutral gases. They automatically maintain a constant lower outlet pressure regardless of inlet pressure fluctuations or flow changes. These models are simple, robust and widely used in steam distribution, compressed air systems and water networks.
