Cla-Val Altitude Valve beats cavitation in a quiet corner of Newfoundland Installing a Cla-Val 210-FF Altitude Valve with anti-cavitation trim adjacent to the new water tank shown below was the ideal solution to prevent cavitation during filling. The challenge was a high inlet pressure of 135 PSI and a low downstream pressure of 18 PSI which created a differential pressure of 117 PSI. Under normal circumstances, the valve would have gone wide
