Series 618

With proportional opening characteristics and even larger setting ranges of the springs, this valve is ideally suited in cases where a stock value for various applications and set pressures is required and the valve needs to be readily available.

It is designed in particular for plants in which only low amounts of expansion medium have to be discharged.
