An inlet isolation valve is integrated into the pump to close off the inlet port whenever power to the pump is interrupted. This antibackstream valve maintains vacuum in the roughing, or fore-line, and prevents pump oil from contaminating the vacuum chamber. The DS-602 has a manual gas-ballast valve, which when opened, allows the pump to achieve its rated water-vapor handling specification of 550 gr/hr.
