Mass flow controller (MFC) VEFC-L-6-100-D31-Q10-Q10-MRM1

The Festo 8204591 is an electrically actuated 2-way proportional flow control valve featuring an IP20 degree of protection, a non-reversible flow direction, and QS-10 pneumatic connections for both ports 1 and 2. This component delivers a flow rate control range of 5 l/min to 100 l/min (N2 equivalent, with dynamic and accuracy values applying to setpoint values greater than 10% FS) alongside a total leakage of 0.6 l/h standardized according to SEMI E16 tested with CDA in relative air humidity of 5 to 85% non-condensating. It operates at 0.6 MPa (6 bar) with an inlet pressure range of 0.1 MPa to 0.7 MPa (1 bar to 7 bar; 14.5 psi to 101.5 psi), an output pressure 2 range of -0.1 MPa to 0.35 MPa (-1 bar to 3.5 bar; -14.5 psi to 50.8 psi), an overload pressure of 0.8 MPa (8 bar; 116 psi), and a burst pressure of 2.1 MPa (21 bar; 305 psi) while maintaining suitability for vacuum.

Why no listed price?

Industrial and obsolete parts are priced per enquiry: the final price depends on available stock, condition, quantity, and your delivery destination, so a fixed list price would be misleading. Request a quote and we confirm current pricing, lead time, and sourcing options — including hard-to-find and discontinued Festo references — within one business day.

Engineering context

Identification and RFQ Guidance

Confirm the exact configuration

Use the manufacturer part number and model code—not appearance alone. Connection, size, material, voltage, pressure, seal, and control options can differ within the same product family.

What to include in your RFQ

Provide quantity, delivery country and ZIP/postal code, required condition, target date, and photographs of the existing nameplate when available.
