The Design and manufacture of “CRH” high pressure ball valves is carried out considering extreme operating requirements.
The ball sits between pre-compressed gaskets with floating system , ensuring a perfect tight both at low pressure and under
vacuum.With the increase of internal pressure, a greater contact is obtained between ball and gaskets, permitting perfect
tight even at the highest pressure.
