Original Clippard multi‑pilot spring‑return 3‑way pneumatic valve for industrial pneumatic circuits.

Product Overview

R311 is Clippard Minimatic series 3‑way multi‑pilot spring‑return pneumatic valve. Equipped with four pilot input ports, the valve can be actuated by any single pilot signal, and resets only when all pilot signals disappear. It supports multiple circuit modes: normally‑open, normally‑closed, selector or diverter function, can also be converted to 2‑way valve by plugging exhaust port. Compact brass‑body construction, widely used as maintenance spare part for automation, packaging and special pneumatic control systems

Key Features

• Four pilot input ports, any single pilot can trigger valve actuation
• Spring‑return reset, requires all pilot signals removed for valve reset
• Multiple circuit modes: NO / NC / selector / diverter function available
• Auxiliary override pilot can override all four main pilot inputs
• Compact Minimatic brass housing, micro‑gap snap‑action switching, no blow‑by leakage
