Pressure Relief Valves, Models 6500 and 6600, are designed for refrigeration systems. The 6500 Series valves are targeted toward systems operating with new refrigerant blends. These 360 brass alloy valves have been specifically designed to operate with small- to medium-size systems using R-410A refrigerant. The valve pressure range is 450 to 600 psig at a temperature range of -20Â° to 225Â°F. The 6600 Series are designed to support new refrigerants operating at pressures of 451 psig up to 750 psig at temperatures of -20Â° to 225Â°. The valve body is made of 316 stainless steel, whereas the internal parts are made of 303 stainless steel. The bonnet is constructed of 12L14 steel.
