BFY-CL is a coupling device for the FY family of SMAR positioners, designed for applications in several different models of final control elements. BFY-CL attends to the needs of modulating controls for processes requiring strokes longer than 100 mm in the final control element.

The operation principle of BFY-CL is based on the oblique split rule, reducing a original long stroke to a short one, orthogonal to the original travel.The BFY applications are many. From the modulation in control cylinders of long stroke to acting as floodgates of high capacity.

The BFY-CL is used with the FY301 / FY302 / FY303 / FY400 SMAR positioners – presented in HART®/4-20 mA, Foundation fieldbus™ andProfibus PA communication protocol versions.

Features:

• Easy installation;
• Available in carbon and stainless steel;
• Diagnostics through the FY family positioner;
• Applications diversity.
