Pressure monitoring valve has longitudinally displaceable valve piston mounted in valve chamber at ideal operating pressure to release chamber for free flow

摘要

The pressure monitoring valve (1) includes a longitudinally displaceable valve piston (5) mounted in a valve chamber (6) and which with the ideal operating pressure is held in the transverse direction relative to its longitudinal axis (7) so that the valve chamber is free for the flow of the medium. The valve piston can be associated with a valve sleeve (8) through which the piston is held balanced at the ideal operating pressure.
