Industrial Applications

1. Pneumatic Clamping & Positioning Systems

Used in automated assembly lines where precise cylinder control is required. The 3-position pressure-center function blocks flow and maintains pilot pressure on both sides of a double-acting cylinder when de-energized, locking the clamp securely in place without drifting.

Problem Solved

Prevents pneumatic clamp drift during power-off or emergency stop situations by maintaining balanced pressure across the cylinder chambers.

2. Low-Power Fieldbus Manifold Integration

Integration into high-density industrial manifold blocks using 24V DC systems. With only 0.35W power consumption, multiple valves can be actuated simultaneously from PLC outputs without overloading the power supply or fieldbus coupler.

Problem Solved

Reduces thermal load on control panels and minimizes overall power requirements in automated robotic systems.

3. Inert Gas Purging and Distribution

Controlling the flow of non-reactive inert gases in packaging or manufacturing processes. Its IP65 protection rating allows it to operate reliably in washdown zones, while the soft rubber seal guarantees zero leakage during idle times.

Problem Solved

Eliminates gas leakage during inactive cycle phases while withstanding industrial environment dust and liquid spray.
