EBVT-PR ball valves with built-in pressure equalization is a smart news from Parker. These valves allow positive shut-off in one direction and flow in the other direction in the event of a pressure difference in the refrigerant circuit and thus protect the refrigeration system against excessive pressures during service. No parallel-connected non-return valve with associated piping needs to be installed as the non-return valve is already integrated in the ball valve, which reduces material costs. Compact design simplifies installation. Less soldering results in increased productivity and lower labor costs, and the risk of leakage is also reduced as a result. Solder connections in K65. Starts pressure equalization at pressure difference 0.345 bar and is fully open at 3.45 bar.

A-collection ball valves are approved for subcritical CO2 and made of a strong brass body with copper connectors and brass seal cap. All internal parts are designed to guarantee zero leakage in or out from the valve. The valve is not flow direction dependent. Leak tested with helium at its calculation pressure.
UL and CE approved.
