AUTOMATIC REGULATION

A membrane type differential pressure controller with built-in control valve for flow rate adjustment

FOR APPLICATIONS

Where supply or back pressure varies

STABILIZE MEDIUM FLOWS

The EFR14 constant flow regulator is designed to provide constant flow of medium volume liquid flows in applications where supply or backpressure varies. This regulator is a membrane type differential pressure controller with a built-in needle valve for flow rate adjustment.
ESKO offers two sizes of robust constant flow regulators: the model EFR14 for larger flows readily mounts onto model EM flow meters and the smaller model EFR3 which pairs with model ELF flow meters.
Model EFR14 features solid and heavy-duty stainless steel construction with clearly labelled etched connection points (IN and OUT).
