Refrigera’s new ball valve uses stainless steel with a K65 connection. “This product was developed for the U.S. market to meet the requirements of the UL certification [a U.S. safety body],” Gabriele Bertossi from Refrigera told R744.com.
The valve can be used in transcritical installations safely. “The pressure is very high; we’re talking 150 bars,” Bertossi said.
The company has also launched a new strainer valve with stainless steel and K65, and a V-port valve.
The V shape allows for better control of the refrigerant, according to Bertossi, “so if you open the valve at 60% you will have 60% flow rate [from] the valve”.
