Using a bellows in the pressure sensing part, these control valves are highly responsive even to very small changes in pressure.

EKK’s proprietary Direct Pressure Sensing (DPS) structure is patented (PAT. 4246975).

This structure achieves absolute pressure balance by cancelling the internal pressure.

These automotive air-condition valves control the compressor pressure and rotational load to provide comfortable drive feeling by reduce the clutch shocks and contribute to reduce the fuel consumption.
