VYC 513 514 614 Direct Acting Pressure Reducing Valve with Stainless Steel Internals and Adjustable Outlet Pressure for Steam Gas Regulation
The VYC 513, 514 and 614 are direct-acting pressure reducing valves designed for steam, water, air and non-corrosive gases. The 513 is screwed, 514 is flanged, and 614 is a high-capacity or special version. They reduce high inlet pressure to a stable lower outlet pressure automatically. These valves are simple, reliable and commonly used in steam systems, compressed air lines and water supply where no external power is available.
