Pressure Reducing/Low Flow By-Pass Control Valve

Envotec E5200-16 Pilot Operated Pressure Reducing/ Low Flow By-Pass Control Valve reduces a fluctuating higher upstream pressure to a constant lower downstream pressure regardless of varying flow rates. The Low Flow By-Pass feature within the main valve handles low flow requirements, which is below the range of the main Pressure Reducing Control Valve. When flow demand increases both low flow by-pass PRV and main PRV caters the demand and vice versa when the demand decreases.
