The Festo MHE3-M1H-3/2G-QS-6-K, Festo part number 525152, is a directly actuated 3/2-way, single solenoid, normally closed solenoid valve from the Festo MHE3 fast-switching series. It has a standard nominal flow rate of 200 لتر/دقيقة, QS-6 push-in, 6 mm pneumatic connections, a cable, 2.5 m (pur sheath) electrical connection and runs on 24 فولت DC. Switching time is 8.3 ms on and 4.5 ms off, with a maximum switching frequency of 130 Hz.
The valve body is only 14 mm wide, so valves can be mounted side by side on a 19 mm grid to build a compact bank. The design is a pressure-relief poppet valve with a mechanical spring return and a non-detenting manual override, in a coated die-cast zinc housing rated IP65.

Frequently asked questions
Is the Festo 525152 normally open or normally closed?
It is normally closed (closed at rest, opens when energised).
What is the difference between the Festo M1H and MS1H versions?
The MS1H versions carry integrated electronics: holding-current reduction, spark arresting and a protective circuit. They switch much faster and tolerate far higher switching frequencies. On the MHE3, MS1H switches in about 2.3 ms at up to 280 Hz, while the standard M1H coil switches in about 8.3 ms at up to 130 Hz. The M1H is the simpler and cheaper option where speed is not critical. This item is the M1H version.
What does the -K at the end of a Festo MHE part number mean?
The -K suffix means the valve is supplied with a fixed 2.5 m PUR cable instead of a 2-pin plug. This item is the -K cable version.
Can the Festo MHE3-M1H-3/2G-QS-6-K be used with vacuum?
Yes. The operating pressure range starts at -0.09 MPa (-0.9 bar), so the valve can switch vacuum as well as compressed air. For reversed flow direction the pressure range is limited to -0.09 to 0.1 MPa.
What power supply does it need?
24 V DC, ±10%. Power consumption is 3.7 W (24 V DC) at a 100% duty cycle.
Is this a genuine Festo part?
Yes. RendatSP supplies new, original, factory-packaged Festo parts. Part number 525152 is the official Festo order number for the MHE3-M1H-3/2G-QS-6-K.
All Festo MHE3 models we supply
The MHE3 family shares the same body (14 mm wide, 200 l/min). The models differ in valve function, port type and electrical connection. The current item is shown in bold. If you are not sure which model fits your machine, see our Festo MHE solenoid valve selection guide.
