Festo 9982 MFH-5-1/8 Air Solenoid Valve
Product Overview
Main Functions
- 5/2‑Way Directional Control
Provides two distinct flow states: in the de‑energized state, port 1 connects to port 4, and port 2 exhausts through port 3; when energized, port 1 connects to port 2, and port 4 exhausts through port 5, enabling bidirectional pneumatic actuation.
- Pilot‑Operated Actuation
Uses internal pilot air to drive the main valve, ensuring reliable switching even at low operating pressures.
- Mechanical Spring Return
Automatically resets to the initial position when the solenoid is de‑energized, ensuring fail‑safe operation.
- Manual Override
Equipped with a detenting manual override for commissioning, maintenance, and emergency operation without electrical power.
- Flexible Installation
Supports both sub‑base mounting and direct in‑line installation, with compatibility for standard pneumatic manifolds.
- IP65 Protection
Offers dust‑tight and water‑jet resistant protection, suitable for industrial environments with moisture and contaminants.
