<h2>Overview</h2>
<p>The <strong>Festo MS6-EE-1/2-V24-S</strong> is a 3/2-way normally closed solenoid on/off valve for pressurizing and venting pneumatic installations. This single solenoid, monostable design features a piston spool construction with internal pilot air capability and manual pushing override. It is discontinued by the manufacturer but remains widely used in legacy pneumatic systems for air source safety control.</p>
<h2>Key Features</h2>
<ul>
<li>3/2-way valve function with normally closed, monostable spring reset design</li>
<li>24V DC solenoid coil with 1.5 W power consumption</li>
<li>Operating pressure range 4–18 bar (60–270 PSI)</li>
<li>High flow capacity: 7,000 l/min standard nominal flow rate</li>
<li>Non-detenting manual override for emergency depressurization</li>
<li>G1/2″ (NPT) threaded ports; internal pilot air and non-reversible exhaust flow</li>
<li>IP00/65 electrical rating for indoor and outdoor installations</li>
<li>Piston spool design for smooth operation and reliability</li>
</ul>
