Festo
8203266
Mass flow controller (MFC) VEFC
The Festo part number 8203266 is an electrically actuated 2-way proportional flow control valve featuring a non-reversible flow direction and a flow rate control range of 5 l/min to 200 l/min (N2 equivalent). It operates at an operating pressure of 0.6 MPa (6 bar), an overload pressure of 0.8 MPa (8 bar / 116 psi), and a burst pressure of 2.1 MPa (21 bar / 305 psi), with an IP20 degree of protection and vacuum suitability. This unit accommodates inlet pressures from 0.1 MPa to 0.7 MPa (1 bar to 7 bar / 14.5 psi to 101.5 psi) and output pressures from -0.1 MPa to 0.35 MPa (-1 bar to 3.5 bar / -14.5 psi to 50.8 psi) via G1/4, R1/4, QS-8, QS-10, or front metal seal 1/4" pneumatic connections.
