Overview
The Burkert 0331 C 1/8 FPM BR solenoid valve is a direct-acting, media-separated 3/2-way solenoid control valve designed for industrial pneumatic and hydraulic applications. Rated for 120V AC 60Hz at 8W power consumption, this valve delivers reliable on/off flow control for cut-off, distribution, and mixing operations. The “C” designation indicates normally-closed (NC) circuit function—the valve remains closed with no current applied. The 1/8″ port size and FPM (Viton) diaphragm make this unit compatible with standard fluid power manifolds and hose connections.
Key Features
- Direct-acting pivoted armature design for positive, snap-action response
- Media-separated operation: diaphragm isolates solenoid coil from process fluid
- Brass body construction with epoxy-molded solenoid coil for corrosion resistance
- 3/2-way, normally-closed configuration for safe, fail-safe shut-off
- FPM (Viton) diaphragm material for broad chemical and hydraulic fluid compatibility
- Manual override for start-up, testing, and emergency manual operation
- Low power draw (8W) reduces control circuit load
