6 Technical data
It is important to observe the technical data during installation, operation and maintenance.
Inform the personnel about the technical data.
6.1 Technical data
Unique is remote-controlled by means of compressed air. The valve is a normally closed (NC) valve.
The valve has two independent plug seals, forming a leakage chamber between them under atmospheric pressure during every
working condition. In case of rare accidental leaking of product, this will flow into the leakage chamber and be discharged
through the leakage outlet.

Noise
One metre away from - and 1.6 metre above the exhaust the noise level of a valve actuator will be approimately 77db(A) without
noise damper and approximately 72 db(A) with damper - measured at 7 bars air-pressure.
