Festo recently introduced the manually operated VHEF and the mechanically operated VMEF pneumatic valves. These small, durable, and versatile valves are core Festo products and guaranteed to ship within 24 hours.
Whether the valve is triggered by a workpiece, a component, or a person, manual and mechanical valves are the most direct way to control a process. VHEF and VMEF do not require energy conversion, additional reaction time, or long cables. The actuated plunger simply switches the valve and triggers the next step in the process. Given that the conditions in the field are sometimes quite harsh, for example with sawdust in furniture production, or even in agricultural automation, these manual and mechanical valves are designed to withstand environmental stresses.
Each style of valve offers multiple configurations to satisfy a wide range of applications. The VHEF has seven manual versions, including pushbutton, toggle, finger, hand, and selector. The mechanically operated VMEF offers four actuation versions, including stem, roller lever, roller lever with idle return, and piloted.
Both VHEF and VMEF offer 3/2 or 5/2-way functionality. Flow rates are up to 1,200 lpm, pressure ranges from vacuum to 10 bar. Tried-and-tested piston spool and disc seat valves deliver reliable operation. Each valve features a robust metal housing for durability. Thread or connectors provide airline hookup. Multiple mounting options are available for both styles. Inch and metric units are included in this new series.
