Operating Conditions
-
Operating medium: Compressed air / inert gas (standard pneumatic medium).
-
Operating pressure range: Vacuum to approx 10 bar (150 PSI).
-
Temperature range: Ambient typically –23 °C to +46 °C (–10 °F … +115 °F).
-
Flow capacity: Mark 15 valves typically offer higher flow than smaller series — up to ~65–70 SCFM depending on port size and configuration.
⚙️ Valve Function
-
Directional control: Usually 4-way, 2-position or 3-position based on suffix.
-
Solenoid Actuation: Part of the Mark 15 specification allows both direct solenoid and air-pilot solenoid configurations.
-
Mounting: Base or manifold mounting — plug-in solenoid capsules allow fast replacement without disconnecting piping.
-
Sealing: Typically usable in lubricated or unlubricated pneumatic service.
